Complete the balanced molecular reaction for the following weak acid with a strong base:HNO2(aq) + Ca(OH)2 (aq)

Chemistry

Answer:

2HNO_2(aq)+Ca(OH)_2(aq)\rightarrow H_2O(l)+Ca(NO_2)_2(aq)

Explanation:

Hello.

In this case, considering that the reaction between nitrous acid and calcium hydroxide yield both water and calcium nitrite as a neutralization chemical reaction:

HNO_2(aq)+Ca(OH)_2(aq)\rightarrow H_2O(l)+Ca(NO_2)_2(aq)

As it is not balanced due to the two nitrites at the right, we obtain:

2HNO_2(aq)+Ca(OH)_2(aq)\rightarrow H_2O(l)+Ca(NO_2)_2(aq)

Which means that 2 before the nitrous acid balance both nitrogen and oxygen.

Regards.

If 450.0 mL of a 0.500 M solution is mixed with 200.0 mL of water, what is the molarity of the new
Oksana_A [137]

Answer:

Answer: A) .346 M

Explanation:

Given:

- 450 mL

- .5 M soln

-200 mL water

1) Convert mL to L

450 mL = .45 L

200 mL = .2 L

2) Find mols in solution

.5 M = x/.45 L

x = .225 mol

3) Find total volume of solution

.45 L + .2 L =.65 L

4) Find new molarity

molarity (M) = mols solute/ L solution

y = .225 mol (from step 2)/ .65 L (from step 3)

y = .346 M

Answer: A) .346 M
