Ch. 10 Chemical Reactions Flashcards
Evidence of a chemical reaction
- Tomato smells rotten,
- drain cleaner is mixed with water and the solution becomes warm,
- candle wax burns,
- green leaves turn yellow and red as the seasons change,
- baking powder produces a gas that makes a cake rise
Things that are Reactants
The feel for the space shuttle is hydrogen which burns and oxygen to provide water vapor and energy this chemical reaction hydrogen is a reactive oxygen is a reactant and water vapor is a product
In the chemical equation for this reaction a _________ is used to separate hydrogen oxygen from water vapor and energy
Arrow
A _______ used to separate the symbols for hydrogen and oxygen
Plus sign
Decomposition
QT —> Q +T
Double replacement
QT + XZ —> OZ + XT
