Answer:
a) false
b) true
c) false
d) false
Explanation:
Step 1: Data given
Molar mass H2O = 18.02 g/mol
Number of Avogadro = 6.022 * 10^23
Step 2: The balanced equation
3NaHCO3(aq) + C2H3O2(aq) —> 3CO2(g) + 3H2O(l) +NaC2H3O2(aq)
a. 22.4 L of CO2 (g) are produced for every liter of C2H3O2 (aq) reacted.
False, for every liter C2H3O2 we'll have 3 liter of CO2
b. 1 mole of water is produced for every mole of carbon dioxide produced.
True, For 3 moles NaHCO3 we need 1 mol C2H3O2 to produce 3 moles CO2, 3 moles H2O and 1 mol NaC2H3O2
c. 6.02 x1023 molecules of NaC2H3O2 (aq) are produced for every mole of NaHCO3(aq) used.
False, for every 3 moles NaHCO3 we'll have 1 mol NaC2H3O2. This means for every mol NaHCO3 we'll have 1/3 * 6.02*10^23 molecules of NaC2H3O2
d. 54 g of water are produced for every mole of NaHCO3(aq) produced.
False, for every mol NaHCO3 we'll have 1 mol H2O produced
1 mol H2O = 18.02 grams of H2O
