Determine the empirical formula of a compound that has the following percent compositions: % Pt, 2.02% H, 9.34% N, 23.63% Cl.
How many grams CHCl 3 is will be produced from 50.0 g CH 4 ? CH Cl 2 CHCl HCl What will the percent yield be if the actual yield is 400g?
What mass in grams of sodium carbonate, Na 2 CO 3 is produced if 50.0 g of sodium oxide, Na 2 O, are reacted with excess carbon monoxide, CO, according to the following chemical equation? 2Na 2 O (s) + CO (g) Na 2 CO 3(s) + 2 Na (s)
The reaction between solid sodium and iron III oxide is one in a series of reactions that inflates an automobile airbag. Na + Fe 2 O 3 → Na 2 O + Fe If g Na and 100 g of Fe 2 O 3 are used in this reaction determine the limiting reactant and the mass of iron produced.
