C) moisture, falling air, and a lifting mechanism
Answer:
A wave with small amplitude.
Explanation:
Amplitude us inversely proportional to energy so the smaller the amplitude, the higher the energy.
Hope it helps.

In order to find the two statements, we must first define what the enthalpy of formation and the enthalpy of reaction mean.
Enthalpy of formation:
The change in enthalpy when one mole of substance is formed from its constituent elemetns at standard state.
Enthalpy of reaction:
The change in enthalpy when a reaction occurs and the reactants and products are in their standard states.
Now, we check the statements. The true ones are:
The Hrxn for C(s) + O₂(g) → CO₂(g) is the same as Hf for CO₂
This is true because the formation of carbon dioxide requires carbon and oxygen in their standard states.
The Hf for Br₂<span>(l) is 0 kJ/mol by definition.
Because the bromine is present in its standard state, the enthalpy of formation is 0.

The reactants and products are present in their standard state, and the reaction is the same as the one occurring during the formation of ammonia.
