Need this done by the end of today. Amount of rep given will be dependent on how much you do.
Need work shown for most of these.

1. A gaseous compound contains 16.0 g of hydrogen and
96.0 g of carbon. If the molar mass of this compound is
28.06 g/mol, what is its molecular formula?

2. In a blast furnace, iron(III) oxide reacts with carbon
monoxide to produce iron and carbon dioxide.
(a) Identify the limiting reagent if 2.50 mol of iron(III)
oxide and 6.50 mol of carbon monoxide are available.
(b) Identify the limiting reagent if 200.0 g of iron(III) oxide
and 100.0 g of carbon monoxide are available.

3. When 8.40 g of zinc metal is placed in a solution in which
11.6 g of HCI(g) is dissolved, hydrogen gas and zinc
chloride are produced.
(a) Calculate the expected yield of hydrogen gas.
(b) If 0.19 g of hydrogen gas is produced, what is the
percentage yield?

4. A 27.5-mL sample of 0.112 mol/L CuSO4(aq) solution is
added to 45.0 mL of 0.088 mol/L Na2CO3(aq). A precipitate
is formed.
(a) Identify the limiting reagent in the reaction.
(b) Calculate the mass of CuCO3 that is produced in the
reaction.

5. Identify the two acid
