Texts: We have the following reactions: 1) Lead + hydrochloric acid -> lead(II) chloride + hydrogen gas 2) Tin + hydrochloric acid -> stannous chloride + hydrogen gas Assuming that a common solder has 60% tin and 40% lead, and that both reactions have 100% yield, answer the following: a) If 35 g of solder reacts in an excess of acid, calculate the total moles of hydrogen gas that will form. b) Calculate the mass of solder required to produce 0.85 g of hydrogen gas.

          Texts: We have the following reactions:

1) Lead + hydrochloric acid -> lead(II) chloride + hydrogen gas
2) Tin + hydrochloric acid -> stannous chloride + hydrogen gas

Assuming that a common solder has 60% tin and 40% lead, and that both reactions have 100% yield, answer the following:

a) If 35 g of solder reacts in an excess of acid, calculate the total moles of hydrogen gas that will form.
b) Calculate the mass of solder required to produce 0.85 g of hydrogen gas.

Step 1

To calculate the moles of solder used, we need to determine the amount of tin and lead in the solder. Since the solder is 60% tin and 40% lead, we can calculate the moles of tin and lead separately. Mass of tin = 60% of 35 g = 0.6 * 35 g = 21 g Mass of lead = Show more…
