The products of the combustion of candle wax are

5SO2(g) + 2KMnO4(aq) + 2H2O(l) → K2SO4 + 2MnSO4(aq) + 2H2SO4(aq) In the reaction above, the products give a

2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g) In the reaction above, the mass of carbon(IV)oxide produced on burning 78 g of ethyne is [C =12, O = 16, H = 1]

Na2CO3(g) + 2HCl(aq) → 2NaCl(aq) + H2O(l) + CO2(g) How many moles of sodium trioxocarbonate (IV) are there in a 25 cm3 solution which required 10cm3 of 0.05 ...

In the electrolysis of CuSO4(g) using platinum electrodes, the reaction at the anode is

Zinc and carbon rods are used as anode and cathode respectively in a

The solution that will conduct the highest amount of electricity is

If the heat of combustion of hydrogen is -285.8kJ, What is the heat of formation of water?

If 30cm3 of gas at 50oC is warmed to 80o at a fixed pressure, the fractional increase in volume is
