What else can I help you with?
What is the difference of quick lime and washing soda?
Quick lime is calcium oxide. Washing soda is sodium carbonate.
How do limestone absorb carbon dioxide?
yes it does. it absorbs lots of the stuff.. it very usefull it made out of crushed up sea shell carbon dioxide a colourless gas and can be tested by bubbling it through lime water.
What color is more metallic blue green or yellow?
Cobalt oxide is blue Copper oxide is green Chromium oxide is yellow All three are perfectly good metals. I don't think colour has anything to do with the quality of the metal or is a valid measurement of metal-value.
What happens to the formula of zinc oxide when heated?
Zinc Oxide is originally a white powder. When heated up, it turns yellow but does not decompose and when it is removed from the heat it gradually goes back to its original white colour. If you heat it strongly enough to very high tempereatures it will sublime without apparent decomposition. The reason for the yellow colour is that a minute amount of oxyegen evaporates from the lattice (70 ppm) the small number of zinc atoms produce lattice defects that give rise to the colour. Doping zinc oxide with minute traces of zinc will give a range of colours, yellow, green brown and red.
What element turns white when its container was opened?
This element is sodium - a layer of sodium oxide is formed on the surface of the metal.
When Heated a metal carbonate produces what?
Experimentally to prove that, capture the gas and pass it through lime water. If the lime water turns milky then the gas is CO2 . Or an example of equation for decomposition of a metal carbonate is :- MgCO3 + heat ------> MgO + CO2
What decomposes when heated to give zinc oxide?
Zinc carbonate decomposes when heated to give zinc oxide.
What happens to calcium carbonate when heated?
It decomposes into calcium oxide and carbon dioxide
What compound decomposes when it is heated to zinc oxide?
Zinc carbonate decomposes when heated to form zinc oxide and carbon dioxide. This reaction occurs due to the thermal decomposition of zinc carbonate at high temperatures.
What is the word equation for sodium carbonate when heated?
When sodium carbonate is heated, it decomposes into sodium oxide and carbon dioxide. The word equation for this reaction is: Sodium carbonate → Sodium oxide + Carbon dioxide.
What metal when It decomposes it heated it give zinc oxide?
Zinc oxide can be obtained by heating zinc nitrate.
When copper carbonate is heated what ionic compound remains?
When copper carbonate is heated, it decomposes into copper oxide, releasing carbon dioxide gas. The remaining ionic compound is copper oxide (CuO).
Why does barium carbonate decreases its weight when it is heated?
Because it decomposes to form carbon dioxide and barium oxide.
When magnesium carbonate (MgCO3) decomposes it produces a metal oxide and a gas. Predict the products of this reaction?
MgCO3 --> MgO + CO2(g) Magnesium oxide and gaseous carbon dioxide
When solid calcium carbonate is heated what is form?
CaCO3 --> CaO + CO2 Heated Calcium Carbonate (limestone) forms Calcium Oxide (quicklime) and Carbon Dioxide
What substances are created when calcium carbonate is heated very strongly in an open crucible?
Calcium carbonate thermally decomposes when heated to form calcium oxide powder and carbon dioxide gas. The word equation: calcium carbonate --> calcium oxide + carbon dioxide As a symbol equation: CaCO3 --> CaO + CO2
When Calcium carbonate is heated .?
It decomposes into calcium oxide and carbon dioxide...
