Curated OER
Quantitative Problems (Mass)
In this chemistry worksheet, pupils identify how much aluminum and hydrochloric acid is needed to produced a certain amount of hydrogen gas. Then they identify how many grams of oxygen are used.

Production of Hydrogen
Students generate hydrogen gas and examine some of its properities through an experiment. In the experiment, a wood splint is lit along with a candle, then the reaction occurs within the mixture. There are questions for the student to...
