Question

d. 3. Sodium borohydride (NaBH) is a nonhazardous compound used to produce pure hydrogen gas in fuel cells. Based on the submicroscopic representation shown to the right, what is the chemical equation for this process? | Le 2 NaBH4 + 8 H2O 2 NaBOs + 8 H2 + 4H2O NaBH4 + 4 H2O NaBO2+ 4 H2+ 2 H2O d. Which species acts as limiting reactant in the reaction represented in question 3 above? a. H2O Production of hydrogen from sodium borohydride and water releases 210 kJ/mol of energy. 4. b. NaBH c. H2 d. There is no limiting reactant 5. d.

Explanation / Answer

Generally one mole of sodiumborohydride reacts with two moles of water to give 4 moles of hydrogen and sodium borate.it is a balance chemical equation only, we need not to double the quantities as inequation b.
