The oxidation state of Hydrogen in reactant side is 0 and that in product side is +1. Hence the reaction is oxidation.
A would have a higher pitch
The answer is the last one, “The cell membrane is the only source of support and structure in plant and animal cells.” That is false because plant cells have a cell wall and cell membrane while animal cells only have a cell membrane.
Hope this helps:)
KClO3 (aq) will have greater molar entropy than KClO3 (s) because molar entropy increases with increase in temperature.
As the temperature rises, the standard molar entropy of any substance rises. Entropy and a Single Substance's Temperature ” Entropy increases significantly when a solid turns into a liquid and when a liquid turns into a gas. The entropy of the liquid is lower than that of the gas. As a result, entropy rises in reactions that produce gaseous byproducts from solid or liquid reactants. When solid reactants produce liquid products, entropy also rises.
