Carbonic acid forms when carbon dioxide dissolves in water according to this equation:
CO2+H2O =H2CO3
How many moles of CO2 must dissolve in an excess of water to produce 3 moles of H2CO3?
Everything is a one to one ratio.
1 mole needs 1 mole, 2 moles needs 2 moles, and 3 moles needs 3 moles.
3 moles.
To determine the number of moles of CO2 needed to produce 3 moles of H2CO3, we can use the balanced equation:
1 mole of CO2 + 1 mole of H2O produces 1 mole of H2CO3
From the equation, we see that the coefficient in front of CO2 is 1. Therefore, for every 1 mole of CO2, we can produce 1 mole of H2CO3.
To produce 3 moles of H2CO3, we would need 3 moles of CO2. So, 3 moles of CO2 must dissolve in an excess of water to produce 3 moles of H2CO3.
To determine the number of moles of CO2 required to produce 3 moles of H2CO3, we need to use stoichiometry, which is the relationship between the coefficients of substances in a balanced chemical equation.
Given the equation: CO2 + H2O = H2CO3
The coefficients in the equation represent the ratio of moles of each substance. We can see that the coefficient of CO2 is 1, and the coefficient of H2CO3 is also 1. This means that the ratio between CO2 and H2CO3 is 1:1.
Since we want to produce 3 moles of H2CO3, this means we need an equal number of moles of CO2. Therefore, the number of moles of CO2 required is also 3.
Hence, the answer is 3 moles of CO2 must dissolve in an excess of water to produce 3 moles of H2CO3.
