Answer:
C. its particles move farther apart and the substance becomes a gas.
Explanation:
A. is wrong because moving closer together creates a solid, not a gas.
B. is wrong because moving father apart creates a gas, not solid.
C. is correct because moving farther apart creates a gas.
D. is wrong because when heat is added particles spread apart because they vibrate faster. Although, in a solid the particles are closer together.
- Just know the states of matter and how the particles move and that will help with this problem.
Answer:
False
Explanation:
While chemical reactions can proceed in the forward direction , they can in fact also proceed in the backward direction too. The direction they would proceed depends majorly on the state of chemical equilibrium at that particular time for that particular chemical reaction.
It should be known that when a chemical reaction proceeds in the forward way, more products are formed and the reactants are used up. If however, the chemical reaction proceed in the backward way, more reactants are formed and the products are used up.
A practical example is in the case of an exothermic reaction. This is one in which heat is released to the surroundings as a result of the reactants being at a higer energy level compared to the product. Now, depending on the prevailing equilibrium constraint, the reaction could proceed forward or backward.
If for example, the temperature is decreased, this is a constraint being applied to the equilibrium state. The chemical reaction would take a shift and will favor the forward reaction and more of the products will be formed. And also of the temperature is increased, it is the backward reaction that is favored
