If you have 4 Moles of Fe2O3 and 3 Moles of C, which reactant is limiting the following reaction: 2Fe2O3 + 3C → 4Fe + 3CO2?

Which mathematical relationship should you us to convert moles of a substance into grams

How can you use chemical equations to predict the products of the reaction you can carry out?

Sandy is building a small toy car. he wants to use a balloon to power the toy car. he fills a balloon with air and then attaches a straw to the balloon. he tapes the balloon-straw combination to the car and then releases the end of the balloon. the toy moves forward as the air from the balloon comes out the back of the straw. what can sandy do to make the toy car move faster? a) use less air in the balloon. b) blow up the balloon more. c) use a longer straw. d) use larger tires.
