Mass Changes During Chemical Reactions
Added by Dr. Andrew Pulham on Dec 15, 2008
This activity investigates the mass changes that take place when a selection of chemical reactions take place. Experiments are constructed to show mass changes when elements combine with oxygen, during metal-metal salt reactions and when metal carbonates decompose. Conservation of mass during chemical reactions is also reinforced.
This item teaches:
- about the conservation of total mass in chemical reactions
- abuot the formation of oxides from substances burning in air
- about examples that demonstrate the conservation of mass in chemical reactions
- To investigate the mass changes when elements combine with oxygen
- To investigate the mass changes during metal-metal salt reactions
- To investigate the mass changes when metal carbonates decompose
- To reinforce the fact that mass is conserved during chemical reactions
