What is the molarity of a hydrochloric acid solution, HCl (aq), if 30.00 mL of the solution is required to completely react with 25.00 mL of a 0.200 M magnesium hydroxide solution, Mg(OH)2 (aq)? Be sure to write out the balanced chemical
reaction between these two compounds.

0.333 M

Explanation:

Step 1: Write the balanced equation

2 HCl(aq) + Mg(OH)₂(aq) = MgCl₂(aq) + 2 H₂O(l)

Step 2: Calculate the reacting moles of Mg(OH)₂

25.00 mL of a 0.200 M magnesium hydroxide react. The reacting moles of Mg(OH)₂ are:

Step 3: Calculate the reacting moles of HCl

The molar ratio of HCl(aq) to Mg(OH)₂ is 2:1. The reacting moles of HCl are:

Step 4: Calculate the molarity of HCl

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

if you mean hydrogen and oxygen then water is the product
