Combustion
Name 3 Combustion reactions
normally in oxygen / air
2Mg(s) + O²(g) --> 2MgO(s)
2H2 (g) + O2 (g) --> 2H²O(g)
S(s) + O² --> SO² (g)
What flame does the combustion reaction 2Mg(s) + O²(g) --> 2MgO(s) make
A magnesium flare-Bright white
What colour flames does the combustion reaction 2H²(g) + O²(g) --> 2H²O(g) make
Ignighting a ballon filled with hydrogen gas-Orange/Yellow
What colour flame does the combustion reaction S(s) + O²(g) --> 2H²O(g)
Burning sulfur coming from a volcano-Pale blue
If you burn pure hydrogen what would the flame colour be?
Pale blue
If you bun hydrogen in hydrocarbon what colour the flame be?
Orange due to carbon
Are combustion reactions exothermic or endothermic
Exothermic-They produce heat energy
What is a combustion reaction
Burning off fuel normally oxygen
