4NH3 + 5O2 > 4NO + 6H2O What is the maximum number of moles of NO that can be produced when 2.0 moles of NH3 is completely reacted?

Can anyone (a-level) a student was analysing a carbonate compound, mco3, containing an unknown group 2 metal, m. the student carried out thermal decomposition on 0.730g of the carbonate and measured the volume of gas produced. mco3 (s) mo (s) + co2 (g) the student collected and measured 120cm3 of carbon dioxide. 1 mol of carbon dioxide occupies 24 000 cm3 under these conditions. calculate the molar mass of the group 2 carbonate and hence deduce the identity of the group 2 metal, m.

What is the number of moles in 15.0 g ash3?

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion
