Answer:
The answer is "10.84 g".
Explanation:
The formula for calculating the number for moles:
In the given acid nitric:
Owing to the nitric acid mass = 
Nitric acid molar weight
If they put values above the formula, they receive:
In the given chemical equation:
In this reaction, 2 mols of nitric acid are produced by 1 mole of water.
So, 1.204 moles of nitric acid will be produced:
We are now using Equation 1 in determining the quantity of water:
Water moles 
Water weight molar 
Answer:
C. The energy released as the bonds in the reactants are broken is greater than the energy absorbed as the bonds in the product are formed.
Explanation:
As ΔH is negative, the given reaction is exothermic.
That means that <em>the enthalpy of the product is less than the enthalpy of the reactants</em>. In other words, part of the energy from the reactants is used to form new bonds (between C and H, for example), while the other part is transfered outside the system as heat.
Thus the correct answer is C.
Answer:
The rate of a reaction is a measure of how quickly a reactant is used up, or a product is formed.
Explanation:
The answer would be the first one.
