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 ofaluminum?
2.) Convert 1.77×1024 atoms of carbon to moles of carbon.
1.77×1024 atoms=
3.) 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?
4.)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?
PLEASE HELP...I WOULD GREATLY APPRECIATE IT...
