Question

I am HORRIBLE at chemistry, Can somebody help me out with this question please.

Answer 1

Answer:

D

Explanation:

if CO2 +H2O = 1 H2CO3 then 4 CO2 would be 4 moles I think

Answer 2

Answer:

There must dissolve 4 moles of CO2 (Option D is correct)

Explanation:

Step 1: Data given

Number of moles H2CO3 produced = 4 moles

Step 2: The balanced equation

CO2 + H2O → H2CO3

Step 3: Calculate moles of CO2

For 1 mol of CO2 we need 1 mol of H2O to produce 1 mol of H2CO3

For 4 moles H2CO3 produced we need 4 moles of CO2.

There must dissolve 4 moles of CO2 (Option D is correct)
