Answer: The products usually weigh more than the reactants.

Answer:
The answer is Inductive effect
Explanation:
To determine the acidity or alkalinity of an organic compound. We have to keep in mind that the whole analysis is based on the comparison between the compounds, and we must work with the conjugated base of the molecule. Keeping in mind, the more unstable the base, the less acidic the molecule is. Thus, to determine instability, the Inductive Effect of the molecule can be used.
This type of effect occurs when atoms of different electronegativities are linked or very close in the compound. The most electronegative atom has a tendency to bring electrons close to it, thus creating a dipole. This dipole can have a stabilizing effect on the molecule, as it “relieves” the excessive charge on some occasions, better accommodating the charges.
However, in some cases, instead of chains with chlorine radicals, we may have chains with methyl radicals. This has a major impact on the inductive effect, keeping in mind that alkyl groups are electron donors.
Answer:
B
Explanation:
A is not the answer. Although the statement is accurate in regards to gases, it does not explain why liquids and gases can flow.
B is the answer. Solids are in fixed structures. When you apply heat or pressure, these structures are broken apart and allowed to move freely.
C is not the answer. This is inaccurate. Changing the phase of a substance does not change the size of the particle.
D is not the answer. The opposite of this statement is true. The attractive forces between particles in a solid allow the substance to hold its structure. When you apply heat or pressure, the attractive forces are overpowered and the structure is broken.

Stoichiometry measures these quantitative relationships, and is used to determine the amount of products/reactants that are produced/needed in a given reaction.
