PLS HELP! Which of the following statements about the reaction below is true?

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.
b. 1 mole of water is produced for every mole of carbon dioxide produced.
c. 6.02 x1023 molecules of NaC2H3O2 (aq) are produced for every mole of NaHCO3(aq) used.
d. 54 g of water are produced for every mole of NaHCO3(aq) produced.

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

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
