Which two elements in group 14 on the periodic table most likely to be malleable and good conductors of electricity

Answers

Answer:

Tin & Lead

Explanation:

They are metals and can conduct electricity because their outer electrons are not localized, i.e., they are not bound to specific atoms.

The energy level of electrons in the "conduction band" overlaps that of valence electrons. These electrons are more like a cloud dispersed throughout the piece of metal so that when an electric field is applied, they can move around.

The two element in 14th group of periodic table most likely to be malleable and good conductors of electricity  are lead and tin. They are mostly existing in metallic state.

What are conductors ?

Conductors are materials that can easily pass electricity through it at normal temperature. Metals are all good conductors. In addition metals have some peculiar features such as malleability, ductility, luster etc.

14th group elements are carbon family. In this group, carbon at normal temperature exists as gas. Silicon and germanium are semiconductors. Lead and tin are metallic in nature and they are malleable as well.

Lead and tin can be shaped and sized as desired and they are used in various electronic devices also because they are good conductors at metallic state. Therefore, tin and lead are the two elements.

what is a polar functional group?​

Answers

I think this is the answer

Final answer:

A polar functional group is a cluster of atoms within a molecule that has polar preferences due to the uneven distribution of electrons, resulting in areas with partial positive and negative charges which enable it to participate in various chemical reactions and interactions with other polar substances, such as water.

Explanation:

A polar functional group is a specific grouping of atoms within a molecule that has a polarized distribution of charges, which means there is an uneven distribution of electron density. This polarity arises because of the presence of electronegative atoms like oxygen, nitrogen, or fluorine, which attract electrons more strongly than other types of atoms in the functional group. These groups have partial positive and negative charges at different points and are often involved in chemical reactions due to their ability to interact with other molecules and ions. A classic example of a polar functional group is the hydroxyl group (-OH), common in alcohols and known for being hydrophilic or water-loving, meaning it can form hydrogen bonds with water and dissolve easily in it. Other examples include carbonyl groups (C=O) in ketones and aldehydes, carboxyl groups (-COOH) in amino acids and fatty acids, and phosphate groups (-PO4) often found in DNA and ATP.

The Calvin cycle converts ATP and NADPH to
a0

Answers

Answer:

The Calvin cycle converts ATP and NADPH to "convert CO2 to sugar".

Explanation:

When carbon dioxide reaches inside the leaf through pores called stomata in plants and spreads to the chloroplast stroma, it act as the location of Calvin cycle reactions where sugar is naturally produced.The light-independent processes are also called such reactions as they are not primarily guided by light.

The Calvin cycle processes can be separated into three main channels: carbon fixation, reduction, and starting molecule's regeneration as explained below:

Carbon Fixation: Six-carbon compound are generated in this step that bifurcate into two molecules (three-carbon compound) 3-phosphoglyceric acid (3-PGA), catalyzed by the enzyme rubisco or RuBP carboxylase/oxygenase.Reduction: In this phase of the cycle 3-PGA molecules are converted into glyceraldehyde-3-phosphate (G3P) i.e three-carbon sugar by using ATP and NADPH.Regeneration: Many G3P molecules are used to generate glucose, while others have to be recycled to recreate the acceptor RuBP.

what are possible reasons for a percent yield that is under 100%

Answers

Answer:

              Percentage Yield is given as,

                 %age Yield  =  Actual Yield / Theoretical Yield × 100

This shows that the %age yield is directly depending upon the actual yield. And most of the time the percentage yield is less than 100 % because of the following factors.

Impure Starting Materials:

                                           If the starting materials (reactants) are not pure then reaction will not completely form the desired product. Different by products will form which will decrease the %age yield.

Incomplete Reactions:

                                     Not all reactions go to completion. In many reactions the starting material after some time stops forming the product due to different conditions. Some reactions attain equilibrium and stop increasing the amount of product. While, in some reactions a by products (like water) formed often react with the product to give a reverse reactions. Hence, the chemistry of reactions also causes the decrease in %age yield.

Handling:

               Another major reason for decrease in yield is handling the product. Always some of the product is lost during the workup of the reaction like, taking TLC, doing solvent extraction, doing column chromatography, taking characterization spectrums. So, we can conclude that the %age yield will always be less than 100%.

Patrick is giving a presentation on thermal energy to his class. How can he use the terms endothermic and exothermic to explain the
change in thermal energy from one substance to another? Give an example of each term. EXPLAIN

Answers

Answer:

In the study of thermochemical processes, things are viewed from the point of view of the system. A chemical reaction or physical change is endothermic if heat is absorbed by the system from the surroundings. In the course of an endothermic process, the system gains heat from the surroundings and so the temperature of the surroundings decreases. The quantity of heat for a process is represented by the letter q . The sign of  q for an endothermic process is positive because the system is gaining heat. A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings is gaining heat from the system, the temperature of the surroundings increases. The sign of  q for an exothermic process is negative because the system is losing heat.

Explanation:

Final answer:

Patrick can use the terms exothermic and endothermic to explain changes in thermal energy. Exothermic processes release heat into the environment, like burning wood, while endothermic processes absorb heat, like melting ice.

Explanation:

Patrick can explain the change in thermal energy from one substance to another using endothermic and exothermic processes. An exothermic process is one in which heat is released into the surrounding environment. An example of this is the burning of wood in a fireplace where heat is given off as the wood burns, increasing the thermal energy in the room. On the other hand, an endothermic process is one in which heat is absorbed from the surroundings. An example is the melting of ice, which takes heat from the surrounding environment, reducing its thermal energy, to change from a solid to a liquid state. By using these terms, Patrick can effectively explain changes in thermal energy.

Answer:

(gains electrons) .

This transfer makes the sodium atoms  acquire (positive) charge and phosphorous acquire (negative) charge .

As a result, the sodium and phosphorus atoms strongly (attract) with

each other.

Explanation:

In the paragraph about the formation of sodium phosphide: Electrons are transferred from atoms of sodium to atoms of phosphorous. This transfer makes the sodium atoms acquire positive charge and phosphorous acquire negative charge. As a result, the sodium and phosphorus atoms strongly attract each other.

Between the phosphorous (P) and sodium (Na) atoms, electron transfer occurs to generate sodium phosphide. When phosphorus receives electrons from sodium, sodium loses electrons, leaving sodium ions (Na⁺) with a positive charge and phosphide ions (P³⁻) with a negative charge as a result.

The oppositely charged ions are attracted to one another strongly electrostatically as a result of this charge difference. This kind of link, referred to as an ionic bond, results in the creation of sodium phosphide (Na₃P), a stable molecule in which several sodium ions are completely encircled by phosphide ions, solidly keeping them together in a crystal lattice structure.

Suppose the boy skipped his lunch for a day how will the hormones from his pancreasls help his body to cope wwhen his blood sugar level drops below normal​

Answers

Answer:

The hormone glucagon secreted by the pancreatic cells cause the release of glucose from the body's storage.

Explanation:

The pancreas is an organ found inside the abdomen. This organ produces hormones such as:

InsulinGlucagonSomatostatinVasoactive intestinal peptide

Insulin and glucagon are considered primary hormones secreted by the pancreas.

Upon skipping a meal, leading to a drop in blood sugar levels, glucagon is secreted by the pancreas. This hormone then acts on the liver to stimulate the conversion of stored up glycogen present in the liver into glucose. This produced glucose is then released into the blood stream, availing the boy glucose for energy.

 

The hormone of glucagon that is released by pancreas helps the body cope when the blood sugar level drops below normal.

Role of Glucagon

The hormones from his pancreas release glucagon that helps the body to cope when his blood sugar level drops below normal​ because the body needs energy so it takes the sugar from the storage present inside the body. If blood sugar level falls too low, the pancreas releases glucagon which tells the liver to make more glucose.

Glucagon is a hormone that is responsible for the making of glucose from the stored energy in the body so we can conclude that the hormone of glucagon that is released by pancreas helps the body cope when the blood sugar level drops below normal.

How to balance K2SO4+BaCl2= BaSO4+KCl

Answers

Answer:

The answer is K2SO4 + BaCl2 = BaSO4 + 2KCl

Explanation:

First, you can do it by looking how many chlorine is being used. As you can see that 2 chlorine is being used so you are sure that 2 chloine is in the right side.

Secondle, there are also 2 potassium in the left side so there must be also 2 potassium in the right side.

K2 + Cl2 = K2Cl2 (to make it beautiful)

= 2KCl (you can take out 2, just similar to factorisation)

(Hope this can help)

Final answer:

The balanced equation for the reaction between K2SO4 and BaCl2 to produce BaSO4 and KCl is K2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2KCl(aq). BaSO4 is an insoluble precipitate, and the balance is achieved by having 2 moles of KCl in the products to match the potassium atoms.

Explanation:

To balance the chemical equation K2SO4(aq) + BaCl2(aq) → BaSO4(s) + KCl(aq), we need to ensure that the number of atoms of each element on the reactant side is equal to the number on the product side. Initially, we have 2 potassium (K) atoms on the reactant side and only 1 potassium atom on the product side. We also have 1 barium (Ba) atom, 1 sulfate (SO4) group, 2 chloride (Cl) atoms on the reactant side, and the same on the product side. To balance the equation, we simply need to adjust the coefficient in front of KCl to 2, as shown in the balanced equation:

K2SO4(aq) + BaCl2(aq) → BaSO4(s) + 2KCl(aq)

By doing this, we ensure that the number of potassium atoms is now 2 on both sides, and the chlorides are also balanced with 2 atoms on each side. The product BaSO4 is insoluble and will form a precipitate, while the other products remain in solution.
