Calculate how much of a substance is: a) 11 g of carbon dioxide CO2 b) 34.3 g of sulfuric acid H2SO4

a) mco2 = 44g / mol n = 11/44 = 0.25 mol b) mh2so4 = 98g / mol n = 34.3 / 98 = 0.35 mol 5.c) 6.a – 2 b – 3 c – 4 g – 1

With an increase in pressure by compressing the system, the equilibrium shifts towards a decrease in the number of gas molecules, which means that a change in pressure will not cause a shift in equilibrium for reaction 2. when the reaction proceeds without changing the number of gas molecules, equilibrium is not disturbed. This means, moreover, for the reaction. answer: 2 and 3 reactions.

3cl2 + 6koh = 5kcl + kclo3 + 3h2o

n (cl-) = n (kcl) = 0.5 mol

according to the equation n (cl2) = 0.5 * 3/5 = 0.3 mol.

v (cl2) = vm * n (cl2) (vm is the molar volume, equal to 22.4 L / mol at normal conditions)

v (cl2) = 22.4 * 0.3 = 6.72 liters.
