Calculate percent yield or determine the limiting reactant: Use the equation:
2 HCl(aq) + Mg(s) → MgCl2(s) + H2(g)
1. Determine the limiting reactant if you have 20g of HCl and 10g of Mg.
2. Determine the percent yield if you produce 5g of MgCl2 from 20g of HCl. (you
must first calculate theoretical yield).

Agas diffuses 1/7 times faster than hydrogen gas (h2). what is the molar mass of the gas? 100.10 g/mol 98.78 g/mol 86.68 g/mol 79.98 g/mol

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2

Which of these is a physical property
