Answer: The coefficient in front of AgCl when the equation is properly balanced is 2.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Decomposition of silver chloride is represented as:
Thus the coefficient in front of AgCl when the equation is properly balanced is 2.
Answer:
The balanced chemical equation:
Heat of combustion per gram of phenol is 32.454 kJ/g
Heat of combustion per gram of phenol is 3,050 kJ/mol
Explanation:
Heat capacity of calorimeter = C = 11.66 kJ/°C
Initial temperature of the calorimeter =
Final temperature of the calorimeter =
Heat absorbed by calorimeter = Q
Heat released during reaction = Q'
Q' = -Q ( law of conservation of energy)
Energy released on combustion of 1.800 grams of phenol = Q' = -(58.4166 kJ)
Heat of combustion per gram of phenol:
Molar mass of phenol = 94 g/mol
Heat of combustion per gram of phenol:
Hope this helps :) I didn’t know how to write subscripts so I wrote it down on some paper.
