1 answer:
Answer:
A. CaO
Explanation:
Reactant are the species that take part in and also undergoes the reaction to form species which are known as products.
Symbolic representation of the chemical reaction with the help of the formulas and symbols is known as chemical equation. In the chemical equation, reactants are written at left-hand side as well as products are expressed or written on right-hand side. The coefficients which are written before the formulas or the symbols are known as stoichiometric numbers.
Thus, in the reaction shown below:-
<u>Thus, The product of the reaction is:- CaO</u>

Answer:
will be 90054 J
Explanation:
Number of moles = (mass)/(molar mass)
Molar mass of = 134.45 g/mol
So, 1.00 g of =
of
= 0.00744 mol of
0.00744 mol of produces 670 J of heat
So, 1 mol of produces
of heat or 90054 J of heat
