The correct answer is that both living and nonliving things are made of matter. The correct option is: both living and nonliving things.
Living organisms and inanimate objects alike are composed of matter. Essentially, matter is the "stuff" that constitutes everything in existence. Anything that occupies space and has mass qualifies as matter, which consists of various chemical substances.
Therefore, the accurate answer to the question "What is made of matter?" encompasses both living and nonliving entities. This includes everything from the air we breathe to the earth beneath our feet, the food we consume, and our own bodies.
For example, the chair you're sitting on and the meal you had for lunch are both made of matter. Matter, defined as anything that has mass and takes up space, includes all tangible objects in the universe, whether living or nonliving.

The following properties are either physical or chemical. Which one is different from the rest based on those two categories?
Boiling point
Flammability
Magnetism
Thermal conductivity
The property that is different from the rest based on the categories of physical and chemical properties is Boiling point.
Boiling point is a physical property because it is associated with the phase change of a substance from liquid to gas and does not involve a change in the chemical composition of the substance. It is a characteristic of a substance that can be measured at a specific pressure and is used to identify substances.
Flammability is a chemical property because it involves a chemical reaction, specifically combustion, where the substance reacts with oxygen to produce heat and light. This reaction results in the formation of new substances with different chemical compositions.
Magnetism is considered a physical property as it pertains to the behavior of a substance in the presence of a magnetic field. It does not involve a change in the chemical composition of the material.
Thermal conductivity is also a physical property. It measures the ability of a material to conduct heat and is a characteristic that can be measured without changing the chemical identity of the substance.
In summary, boiling point, magnetism, and thermal conductivity are physical properties, while flammability is a chemical property. Boiling point is the one that is different from the rest in terms of the physical and chemical property categories

Which of the following characteristics did john Dalton include in his description of the atom?
Can be more than one!
A. Atoms are smaller than quarks.
B. In any element all the atoms are the same.
C. Atoms exist only on Earth
D. All matter is made up of atoms.
E. Elements in a compound are always in a constant ratio.
John Dalton's atomic theory described atoms as identical within an element, claimed all matter is composed of atoms, and stated that elements combine in constant ratios in compounds.
Explanation:John Dalton included several characteristics in his description of the atom that were fundamental to the formation of atomic theory. According to Dalton, B. In any element all the atoms are the same is a characteristic of atoms. He argued that each element has atoms that are identical in mass and properties but different from atoms of other elements. Another characteristic he proposed was D. All matter is made up of atoms, asserting that these atoms were the smallest particles constituting matter. Lastly, Dalton included that E. Elements in a compound are always in a constant ratio, meaning that compounds are formed by combining different types of atoms in fixed, small, whole-number ratios. Dalton's atomic theory, although later refined and partially revised, laid the groundwork for modern chemistry by providing a conceptual framework for understanding the composition of matter.

AgNO3 + Cu=_Cu(NO3)2 + Ag
need help balancing this equation
Answer:
2AgNO3 + Cu = Cu(NO3)2 + 2Ag
Explanation:
This is a simple substitution reaction.
For the equation to be balanced, the total number of elements on each side of the equation must be equal.
The right hand side contains 2 nitrogen and 6 oxygen, to balance this on the left add 2 to the back of silver nitrate. Thus silver on the right hand side of the equation must be 2.
Thus the equation is balanced.
Final answer:
To balance the chemical equation for the reaction between copper and silver nitrate, ensure you have an equal number of atoms for each element on both sides of the equation, resulting in 2 AgNO3 (aq) + Cu (s) → Cu(NO3)2 (aq) + 2 Ag (s).
Explanation:
To balance the chemical equation Cu (s) + AgNO3(aq) → Cu(NO3)2 (aq) + Ag (s), follow these steps:
Identify the reactants and products to understand what symbols go on each side of the arrow and where the + signs go.
Write the correct formulas for all compounds and elements, ensuring all ionic compounds are charge balanced.
Balance the equation by ensuring the same number of atoms of each element appears on both sides of the reaction.
Here is the balanced chemical equation:
2 AgNO3 (aq) + Cu (s) → Cu(NO3)2 (aq) + 2 Ag (s)
This reaction is an example of a single replacement reaction where silver (Ag) is displaced by copper (Cu). The copper starts as a solid and is oxidized to copper (II) nitrate, while silver nitrate is reduced to solid silver. Remember that the charge conservation is important, and therefore the number of electrons and the total charge must remain equal on both sides of the equation.

a sample of sucrose was burned in a calorimeter, and 41,600 joules oh heat energy were released. which statement is true about the water in the calorimeter?
A sample of sucrose was burned in a calorimeter, and 41,600 joules of heat energy were released. and 13,160 joules of heat energy were absorbed by the cold water.
What is sucrose?Sucrose is a disaccharide made of glucose and fructose. It's commonly known as “table sugar” but it can be found naturally in fruits, vegetables, and nuts.
It is known that when mixing hot water with cold water at equilibrium:
The amount of heat released from hot water = the amount of heat absorbed by cold water.
Two bodies of different temperature when come in contact with each other then heat is transferred from hot body to cold body until a thermal equilibrium is maintained between them.
Hence, when hot water has 13,160 joules of energy then this energy will be absorbed by a sample cold water. This means that hot water has released 13,160 joules of energy.

Sterling silver is:
A) a heterogeneous mixture
B) colloid
C) an element
D) Homogeneous mixture
Answer:
It’s D
Explanation:
It’s an alloy so it is not pure. If you take a small sample and analyze it, the mixture will be similar throughout. Think of Gatorade as a homogeneous mixture because it is the same concentration of all ingredients throughout. Think of pizza for heterogeneous mixtures. There isn’t the pepperoni (or whatever you prefer) throughout.
Sterling silver is a homogeneous mixture, or a solution, because it is a combination of silver and other metals that are uniformly mixed together to create a consistent composition.
Explanation:Sterling silver is considered to be a homogeneous mixture, or a solution. A homogeneous mixture is a combination of two or more substances that are so intimately mixed that they behave as a single substance. In the case of sterling silver, it is a mixture of silver and other metals, such as copper, that are uniformly mixed together to create a uniform composition throughout.

The individual dipole moments in ammonia (NH3) do not cancel each other
out. What is the strongest force that exists between molecules of ammonia?
Answer:
The strongest force that exists between molecules of Ammonia is Hydrogen Bonding.
Explanation:
Hydrogen Bond Interactions are those interactions which are formed between a partial positive hydrogen atom bonded directly to most electronegative atoms (i.e. F, O and N) of one molecule interacts with the partial negative most electronegative atom of another molecule.
Hence, in ammonia the nitrogen atom being more electronegative element than Hydrogen will be having partial negative charge and making the hydrogen atom partial positive. Therefore, the attraction between these partials charges will be the main force of interaction between ammonia molecules.
Other than Hydrogen bonding interactions ammonia will also experience dipole-dipole attraction and London dispersion forces.
What role can fire play in the life cycle of some gymnosperms? It can help cones open and release seeds. It can produce the sticky liquid to help capture pollen. It can allow seeds to develop faster into mature plants. It can prevent plants from releasing too much pollen.
Answer:
The correct answer is : It can help cones to open and release seeds.
Explanation:
Gymnosperms like Conifers and Pines grow in high altitudes under extreme weather conditions. Higher altitudes have severely cold climate accompanied with water mostly remaining in the ice form.This is the reason why the cones produced by these plants are too hard to be destroyed by the extremely harsh conditions.But during germination these cones need to open and release the seeds.The best natural way for this is by the means of fire which burn the outer harder layer of the cone and release the seeds.Answer:

Calcium Oxide will react with ammonium chloride to produce ammonia gas, water vapor, and calcium chloride. If only 16.3 g of ammonia is produced from 112 g of calcium oxide and 224 g of ammonium chloride, what is the percent yield?
Answer:
%age Yield = 22.72 %
Explanation:
The balance chemical equation is as follow;
2 NH₄Cl + CaO → 2 NH₃ + CaCl₂ + H₂O
Step 1: Calculate Moles of CaO, NH₄Cl and NH₃;
CaO:
Moles = Mass / M.Mass
Moles = 112 g / 56.07 g/mol
Moles = 1.99 moles of CaO
NH₄Cl:
Moles = Mass / M.Mass
Moles = 224 g / 53.49 g/mol
Moles = 4.18 moles of NH₄Cl
NH₃:
Moles = Mass / M.Mass
Moles = 16.3 g / 17.03 g/mol
Moles = 0.95 moles of NH₃
Step 2: Calculate Limiting reagent as:
According to equation.
2 moles of NH₄Cl reacts with = 1 mole of CaO
So,
4.18 moles of NH₄Cl will react with = X moles of CaO
Solving for X,
X = 4.18 mol × 1 mol / 2 mol
X = 2.09 mol of CaO
This means that none of the given reagent is limiting reagent. They both are almost equal in number of moles.
Step 3: Calculate Theoretical Yield of NH₃ as;
According to equation.
2 moles of NH₄Cl produced = 2 moles of NH₃
So,
4.18 moles of NH₄Cl will produce = X moles of NH₃
Solving for X,
X = 4.18 mol × 2 mol / 2 mol
X = 4.18 mol of NH₃
Step 4: Calculate Percentage Yield as;
%age Yield = Actual Yield / Theoretical Yield × 100
%age Yield = 0.95 mol / 4.18 × 100
%age Yield = 22.72 %
The percent yield of a reaction is calculated by dividing the actual yield by the theoretical yield and multiplying by 100. In this case, it would involve using stoichiometry to calculate the theoretical yield of NH3 from 112 g of CaO, then dividing the actual yield of 16.3 g by the theoretical yield and multiplying by 100.
Explanation:The percent yield of a reaction is calculated by taking the actual yield (the amount actually produced by the reaction) and dividing it by the theoretical yield (the amount that could have been produced under perfect conditions), then multiplying by 100 to get a percentage. In this case, we don't have the theoretical yield, but we know that 16.3 g of ammonia gas was produced from 112 g of Calcium Oxide and 224 g of ammonium chloride.
The reaction between Calcium Oxide and ammonium chloride is: CaO + 2NH4Cl -> 2NH3 + H2O + CaCl2
First, use stoichiometry to calculate the theoretical yield of NH3 from 112 g of CaO. Then, divide the actual yield by the theoretical yield, and multiply by 100 to get the percent yield.
