SO2 + H2O +_ H2SO3 I need to know how to balance simple direct combination reactions

1 answer:

5 0

Hi so first of all count the number of atoms on both sides.
S = 1
O = 2

H = 2, O = 1

H = 2, S = 1, O = 3

Have a go at multiplying and seeing if you can get each atom to have the same number.

Determine the mass of co2 prodeced by burning enough carbon to produce 5 x 10^2 kj

olga55 [171]

Answer:

= 55.7g

Explanation:

12g of carbon burnt to produce 5x10^2KJ

So, 5x10^2KJ(12g/393.5KJ)=15.2g

Then mas of CO2 is 44g

So, 15.2g(12g/44g)=57.7g

What is the molarity of potassium ions in a 0.122 M K2CrO4 solution

Viefleur [7K]

The molarity of potassium ions in a 0.122 M K2CrO4 is 0.244 M

<u><em>Explanation</em></u>

write dissociation reaction for K2CrO4

that K2CrO4 (aq)→ 2K^+ (aq) + CrO4^2- (aq)

K2CrO4 dissociate to give 2 ions of potassium ,therefore the molarity of potassium ion = 2 x 0.122 = 0.244 M
