What black solid reacts with oxygen to make carbon dioxide?
Coal
What is an impurity in coal?
black lump
What is the equation for when coal reacts with oxygen?
C(s) + O2(g) → CO2 (g)
Element that is a yellow solid found as an impurity in coal?
An element that is a yellow solid and found as an impurity in coal is sulfur. Sulfur is one reason why burning coal creates pollution. When impure coal is burned, sulfur dioxide is created and contributes to phenomena such as acid rain.
How is oxygen removed from iron ore?
Iron ore is mixed with coke (almost pure carbon from coal) and roasted at high temperatures. The carbon reacts with the oxygen to produce carbon dioxide leaving the elemental iron.
What black solid reacts with oxygen to make carbon dioxide?
Coal
When coal burns is it a chemical reaction?
Burning coal is a chemical process in which coal reacts with oxygen and forming carbon doxide and or monoxide.

When coal is burnt in power stations which oxides can be released which can react with water vapour in clouds to form acid rain?
the sulphur is a base in fossil fuels (in this case coal). when the coal burns the sulphur reacts with the oxygen in the air to produce sulphur dioxide which reacts with water vapour to form acid rain
How do you compare the dry and wet process of coal washing?
Impurity type
How is oxygen removed from iron ore?
Iron ore is mixed with coke (almost pure carbon from coal) and roasted at high temperatures. The carbon reacts with the oxygen to produce carbon dioxide leaving the elemental iron.
Is burning coal a chemical or physical reaction?
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
What kind of change forms when coal burns?
By burning it - usually (but not always) in order to turn water into steam, and using the steam to turn turbines.
What happens when coal is burn without oxygen?
Coal cannot burn without oxygen.
Is their oxygen where coal present?
no there is not
