IB Chemistry Quiz (DP1)

What is the sum of the coefficients when the equation is balanced with whole numbers?

—C₈H₁₈ (g) + —O₂ (g) → —CO (g) + —H₂O(l)

What is the maximum volume, in dm³, of CO₂ (g) produced when 1.00 g of CaCO₃ (s) reacts with

20.0cm³ of 2.00mol dm^-3 HCl(aq)?

CaCO₃ (s) + 2HCl (aq) → CaCl₂ (aq) + H₂O (l) + CO2 (g)

Molar volume of gas = 22.7 dm³ mol^-1;

Mr (CaCO₃) = 100.00

Which factors affect the molar volume of an ideal gas?

I. Pressure

II. Temperature

III. Empirical formula
