Answer: Relative humidity
Explanation:
Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor has higher relative humidity in cool air than in warm air. A related parameter to that regard is that of dew point.
Answer:
20 moles
Explanation:
4 Fe + 3O₂ → Fe₂O₃
The chemical equation provided is not yet balanced so let's start by balancing it.
4 Fe + 3O₂ → 2 Fe₂O₃
The equation is now balanced with 4 Fe atoms and 6 O atoms on both sides of the equation. It is important to ensure that the chemical equation is balanced, as only then will it tell you the relationship of the reactants and products in terms of mole.
Looking at the coefficients of Fe and Fe₂O₃, 4 moles of Fe is needed to make 2 moles of Fe₂O₃.
This can be simplified into the mole ratio below.
Fe: Fe₂O₃= 2: 1
This means that for every mole of Fe₂O₃, twice the amount of Fe (in moles) is needed.
Thus for 10 moles of Fe₂O₃,
amount of Fe needed
= 10 ×2
= 20 moles
Answer:
Remove exess water
Explanation:
The reaction involved is an esterification reaction. Esterification is a reaction in which alcohol and carboxylic acid reacts to yield an ester and water. It is analogous to the inorganic neutralization reaction.
According to Le Chatelier's principle , one method of driving the equilibrium towards the forward reaction is by removal of one of the products. In this case, if water is removed, the forward reaction is favoured.
