1.) For the chemical reaction 2 Al + 3 H 2 SO 4 ⟶ 3 H 2 + Al 2 ( SO 4 ) 3 what mass of hydrogen is produced from 1.97 mol of aluminum?

2.) Convert 1.77×1024 atoms of carbon to moles of carbon.

1.77×1024 atoms=

3.)

Consider the combustion reaction for octane (C8H18), which is a primary component of gasoline.

2C8H18+25O2⟶16CO2+18H2O

How many moles of CO2 are emitted into the atmosphere when 17.1 g C8H18 is burned?

4.) For the reaction

2KI+Pb(NO3)2⟶PbI2+2KNO3how many grams of lead(II) iodide, PbI₂, are produced from 89.7 g of potassium iodide, KI?

5.)For the reaction

2NaOH+H2SO4⟶Na2SO4+2H2O

how many grams of sulfuric acid, H₂SO₄, are needed to react completely with 33.1 g of sodium hydroxide, NaOH?
