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

the answer is   c.) 1575 j.

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
