. In a titration, a 25.0 mL sample of 0.150 M HCl is neutralized with 44.45 mL of Ba(OH)2. a. Write the balanced molecular equat
choli [55]

Answer:

Equation of reaction:

a) 2HCl + Ba(OH)2 ==> CaCl2 + 2H2O

b) Molarity of base = 0.042 M.

Explanation:

Using titration equation

CAVA/CBVB = NA/NB

Where NA is the number of mole of acid = 2

NB is the number of mole of base = 1

CA is the molarity of acid =0.15M

CB is the molarity of base = to be calculated

VA is the volume of acid = 25 ml

VB is the volume of base = 44.45mL

Substituting

0.15×25/CB×44.45 = 2/1

Therefore CB =0.15×25×1/44.45×2

CB = 0.042 M.

For questions #8 – 9 use the following pictures:
Annette [7]
8. The picture that would best represent atoms in the gas of a neon sign is the image B. This is because they have room for movement in that their distance between each particle is great. That is why gases has greater volume compared to liquids and solids.

<span>9. The picture that would best represent a rock is the image C. The solid molecules are so pact that they have no room for movement.</span>
