# Welcome to the Haltom Science Practice Website

You will find some web sites here where you can practice science problems.

The sites record your answers, so that your teacher can keep track of your progress

Sometimes teachers may offer extra credit, grade replacement, or assign homework from these sites**

## Unit 10 - Stoichiometry

### Choose from the types of stoichiometry practice types shown below.
- Stoichiometry - Grams to Grams
Stoichiometry calculations from reactant in grams to product in grams.

- Stoichiometry - Limiting Reactants (under constuction)
Stoichometry calculations with two givens, one of which is limiting.

Determine which, calculate product grams, and remaining excess reactant.

## Unit 11 - Gas Laws

Practice calculating answers to problems using the various gas laws

Some background from an outside source about gas laws and the people who developed them.
