Answer: Since this is merely a Physical Change, it is improper to write it as a chemical equation.
The reaction of Ca(oH)2 with HCl produces calcium chloride (CaCl2) and water (H2O). The stiochiometric equation is 2HCl + Ca(OH)2 = CaCl2 + 2H2O. In this case, 2 moles of HCl stoichiometrically reacts with one mole of calcium hydroxide. Hence for 3.5 moles of Ca(OH)2, there should be 1.75 moles of HCl needed. Given 0.85 M HCl, to get the volume, we divide 1.75 moles by 0.85 M. The volume needed is 2.0588 liters.
Answer:
A balanced chemical equation explicitly provides you with the
a. conditions under which the reaction occurs.
b. molar masses of the reactants and products.
c. conversion factors needed to solve a stoichiometry problem.
d. mole ratios needed to solve a stoichiometry problem.
The correct answer to the question is
d. mole ratios needed to solve a stoichiometry problem.
Explanation:
A chemical reaction is sad to be balanced if it contains the complete list of reactants and products present in their relative proportions. The amounts of reactants and products can be calculated from a balanced chemical reaction equation by applying a process known as stoichiometry
An example of stoichiometry is the formation of two moles of water from one mole of oxygen and two moles of hydrogen
