When calcium oxide is reacted with chlorine what is formed?
calcium chloride
What is formed when calcium carbonate decomposes?
quicklime (calcium oxide) is formed when calcium carbonate decomposes, as well as releasing carbon dioxide
What salt is formed when calcium oxide reacts with sulphuric acid?
calcium sulfate and water
What element is removed from chromium oxide in a furnace blast?
oxygen by charlie marris because I'm cool
Why aqueous solution of oxide of calcium is basic?
because when it is dissolved in water calcium hydroxide is formed
Does iron ore slag sink to the bottom of the blast furnace?
Slag is the waste which is skimmed off the top of the molten iron that comes out of the blast furnace. It is a mixture of calcium and magnesium compounds, plus other impurities such as iron oxide, but is mainly calcium silicate. The formula for calcium silicate is CaSiO3.
When calcium oxide is reacted with chlorine what is formed?
calcium chloride
Is iron oxide ruduced or oxidised in a blast furnace?
It is 96% iron (the rest is mostly sulphur etc.).
What product can be made by adding water to calcium oxide?
calcium hydroxide is formed.
The compound formed by the reaction between calcium oxide and silica?
Calcium silicate.
What is formed when calcium carbonate decomposes?
quicklime (calcium oxide) is formed when calcium carbonate decomposes, as well as releasing carbon dioxide
What is formed when calcium metal burns in air?
Calcium oxide (CaO), and calcium nitride (Ca3N2)
When calcium is burned calcium oxide is formed whats the word equation for this and reaction type?
I'm sure it's an oxidation reaction. calcium + oxygen gas ---> Calcium oxide
What salt is formed when calcium oxide reacts with sulphuric acid?
calcium sulfate and water
What element is removed from chromium oxide in a furnace blast?
oxygen by charlie marris because I'm cool
Why aqueous solution of oxide of calcium is basic?
because when it is dissolved in water calcium hydroxide is formed
When carbon iv oxide is bubbled through calcium hydroxide what is the white precipitate formed?
The precipitate formed is Calcium Carbonate (CaCO3).
