Enter your answer in the provided box. calcium hydroxide may be used to neutralize (completely react with) aqueous hydrochloric acid. calculate the number of g of hydrochloric acid that would be neutralized by 0.685 mol of solid calcium hydroxide. g hci

49.95 g of HCl

Explanation:

Let's formulate the chemical equation involved in the process:

Ca(OH)2 + 2 HCl → CaCl2 + 2 H2O

This means that we need 1 mole of Calcium hydroxide to neutralize 2 moles of hydrochloric acid. From this, we calculate the quantity of HCl moles that would be neutralized by 0.685 moles of Ca(OH)2

1 mole Ca(OH)2 2 moles HCl

0.685 moles Ca(OH)2 x = 1.37 moles HCl

Now that we know the quantity of HCl moles that would react, let's calculate the quantity of grams this moles represent:

1 mole of HCl 36.46094 g

1.37 moles x = 49.95 g of HCl

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.

the ratio of the conjugate base to the acid required to attain the desired ph.
