amount of CaO that would be produced when 35.5g of CaCO3 decompose on heating (Ca= 40, O = 16, C = 12, H = 1
just put the values to have answer
The major idea behind why having a thick, heavy chimney over a thin, metal chimney for heating a home for a longer period is because it retains a lot of heat and this means energy saving, hence it fuel efficient and cost effective
A metal is a good conductor of heat, this property will make it easily give out head that is needed to the surrounding especially at night, therefore a thick chimney especially made from clay material will be a better choice over a thin metal

Answer:
Volume in litter = 0.8 L
Explanation:
Given data:
Mass of KOH = 112 g
Molarity of KOH = 2.5 M
Volume = ?
Solution:
Number of moles of KOH:
Number of moles = mass/ molar mass
Number of moles = 112 g/ 56 g/mol
Number of moles = 2 mol
Volume of KOH:
Molarity = number of moles / volume in litter
Volume in litter = number of moles / Molarity
Volume in litter = 2 mol / 2.5 mol/L
Volume in litter = 0.8 L
