Chapter , Problem 77(choose chapter or problem)
The mass of a sample of magnesium is obtained and the sample is placed in a container of hydrochloric acid. A chemical reaction occurs according to the equation Mg(s) + 2HCl(aq) H 2 (g) + MgC l 2 (aq). Use the data in Table 16.5 to calculate the volume of hydrogen gas produced at STP during the 3.00-min reaction? (Hint: 1 mol of an ideal gas occupies 22.4 L at STP) Table 16.5 Reaction of Magnesium and Hydrochloric Acid Time (min) Mass of Magnesium (g) Volume of Hydrogen at STP (L) 0.00 6.00 0.00 3.00 4.50 ?
