An aqueous solution of compound X reacts with aqueous sodium hydroxide to form a green precipitate and then aluminium powder is added. The mixture is heated and a gas that turns damp red litmus paper blue is given off. What is X? A ammonium nitrate

B copper(II) chloride

C iron(II) nitrate

D iron(III) chloride

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

In which phase(s) do the molecules take the shape of the container?
