Chemical Reactions & Balancing Practice

Law of conservation of matter (or mass)

matter is neither created or destroyed, only rearrar

amount of reactants =

amount of products

N2 + O2 - NO balanced 

N2+O2 - 2NO 

CO2 — C+O2

Decomposition 

NaCL+AGNO3 — NaNO3 + AgCI

double replacement

S+Cl2 —- SCL2

synthesis reaction

Synthesis reaction 

A type of chemical reaction where two or more substances combine to form a single product.

Decomposition

reaction where a single compound breaks down into two or more products.

Single Replacement

A type of chemical reaction where one element displaces another in a compound, resulting in the formation of a new element and a new compound.

Double Replacement 

A type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Combustion

A chemical reaction that occurs when a substance reacts rapidly with oxygen, producing heat and light, typically resulting in the formation of carbon dioxide and water.

Reaction does not occur

NO REACTION

General equation for a single Replacement reaction

element + compound = element + compound

Soluble 

A substance that can be dissolved in a solvent, typically water, to form a solution.

Slightly Soluble

A substance that can dissolve in a solvent to a limited extent, resulting in a solution with low concentration.

insoluble

A substance that does not dissolve in a solvent, resulting in little to no solution formation.

decomposes 

to break down into simpler substances or compounds, usually as a result of a chemical reaction.

2 Li + 1Ca(NO3)2 =

1Ca+2Li(NO3)

6Li+1Al(SO4)3 =

2AL+3Li2(SO4)

2Ga+3Cd(NO3)2 =

3cd+Ga(NO3)3
