Title: Finals practice question - Please help
Post by: randomusername123 on June 09, 2018, 08:13:39 PM

Calcium hydroxide is used to neutralize acid spills. When calcium hydroxide reacts with Hydrochloric acid a double replacement reaction takes place, forming calcium chloride and water.

a. Write the balanced equation for the reaction of calcium hydroxide and hydrochloric acid to form calcium chloride and water.

b. If you have spilled 6.3 mol of HCL and put 2.8 mol of Ca(OH)2 on it, which substance is the limiting reactant?

c. How many moles of the excess reactant remain?

d. How many moles of calcium chloride are theoretically formed in the reaction?

Thanks in advance.
