Question

what volume of carbon dioxide is formed by a complete combustion of 3.0 g of carbon​

Answer 1

Answer:

V=5,6 dm³

Explanation:

Step 1:First write a balanced chemical equation for the reaction.

Step 2:Calculate the number of moles of C

Step 3:Compare the ratio of C and CO2 and do the cross multiplication to find the number of moles of CO2

Step 4:Provided that the reaction is at STP, use the formula n=V/Vm, where Vm=22,4 dm³. Do the substitution and solve for V
