Question

In the lab, students generated and collected hydrogen gas according to the following equation: Mg(s) + 2 HCl(aq) MgCl2(aq) + H2(g)

In the lab, students generated and collected hydrogen gas according to the following equation: Mg(s) + 2 HCI(aq) →M9CI2(aq) + H2(g) x Incorrect. Did you convert g to mol and then use the mole to mole ratio from the balanced chemical equation to determine the number of moles of H2 generated? (a) How many L of hydrogen gas at STP were generated from 42.9 g of magnesium metal? The number of significant digits is set to 3; the tolerance is +/-1 in the 3rd significant digit SHOW HINT X Incorrect. Did you use the molar volume of a gas at STP to determine the number of moles of HCl required? (b) How many moles of HCl would be required to generate 825 ml of hydrogen gas at STP? mol HCI The number of significant digits is set to 3; the tolerance is +/-1 in the 3rd significant digit hit
