You have a 3.0 g of solid magnesium metal in 250 ml of 1.0mol/l hydrochloric acid solution that is in the beaker. you place a large gas collecting tube over the magnesium and vollect the product, hydrogen gas. assume all the conditions at the lab are SATP.
a) write a chemical balanced equation
b) calculate the number of theoretical moles of hydrogen that should be reduced in this reaction.
c) calculate the volume of hydrogen gas produced. remember that the gas is collected over water.
d) you now quickly do a burning splint test on the hydrogen. jt reacts with just enough oxygen in the gas collecting tube to produce liquid water. what mass of liquid water is produced? (new balanced equation)
