a. If 0.25 mol Na2CO3 completely reacts with excess HCl, how many moles of NaCl and CO2

will be produced, respectively?

b. If 6.02 x 1022 particles of NaBr completely react with excess Ca(OH)2, how many particles of NaOH will be produced?

c. If 204.45 g of NH3 is completed used up in the reaction, how many grams of (NH4)2SO4 will be produced?

d. If 1 mol C5H9O reacts with 2 mol O2, how many mol of CO2 will be produced?

If 4.66 moles of C5H12 reacts with excess O2, how many moles of CO2 will be produced in the following combustion reaction? (C_{5}H_{12} + 8O_{2} - - -> 6H_{2}O + 5CO_{2})

Consider the following balanced reaction:

2c4h10 (g)+13o2 (g)-->8co2 (g)+10h2o (g)

Need to show all work.

If 7.0 moles of c4h10 are completely reacted, how many moles of co2 are produced?

If 19.0 moles of h2o are formed, how many moles of o2 required?

If 17.50 moles of c4h10 are completely reacted, how many grams of h2o are produced?

If 23.0 moles of o2 are completely reacted, how many grams of c4h10 were required?

If 156.0 grams of c4h10 are completely reacted, how many moles of co2 are produced?

If 80.0 grams of c4h10 are allowed to react with 550.0 grams of o2, how many grams of CO2 are produced?
