Answer:
The ΔH is 5.5 kJ/mol and the reaction is endothermic.
Explanation:
To calculate the ∆H (heat of reaction) of the combustion reaction, that is, the heat that accompanies the entire reaction, you must make the total sum of all the heats of the products and of the reagents affected by their stoichiometric coefficient ( number of molecules of each compound participating in the reaction) and finally subtract them:
Combustion enthalpy = ΔH = ∑H products - ∑Hreactants
In this case:
ΔH = 15.7 kJ/mol - 10.2 kJ/mol= 5.5 kJ/mol
An endothermic reaction is one whose enthalpy value is positive, that is, the system absorbs heat from the environment (ΔH> 0).
<u><em>The ΔH is 5.5 kJ/mol and the reaction is endothermic.</em></u>

When water is added to a compound in a chemical equation, a new compound can be formed, it is called a hydrolysis reaction.
<h3>What is hydrolysis reaction?</h3>
There are so many kinds of reaction in chemistry we know that a chemical reaction occurs between reactant molecules in order to yield products in the reactants.
The hydrolysis reaction is a breaking up reaction. In a hydrolysis reaction, water is used to break up a molecule. Hence in a hydrolysis reaction water could be regarded as one of the reactants in the reactions going on in the system.
We know that a hydrolysis is a reaction in which water reacts with another reactant molecule to yield products in the reaction. Thus, when water is added to a compound in a chemical equation, a new compound can be formed, it is called a hydrolysis reaction.

Answer:
10g Carbon has more particles.
Explanation:
To Find
Which has more particles 10g of C or 10g of Ca
The molar mass of carbon is 12g and Calcium is 40g.
1 mole of atom , molecule or ions contain Avagadro number (6.022×10∧23) of particles and also have a mass equal to it's molar mass.
For C,
12g C will have 6.022×10∧23 atoms
10g C will have 
×6.022×10∧23 atoms
=0.833 × 10∧23 atoms
For Ca,
1 mole Ca =40g
40g Ca will have 6.022×10∧23 atoms
10g Ca will have 
×6.022×10∧23 atoms
=0.25 × 6.022×10∧23 atoms
