Question

Calculate the mass of 60 h2so4 required to decompose chalk

Answer 1

Answer:

Explanation:

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.

Answer 2

Answer:

Answer:-

$.$

1 mole of H2SO4 reacts with 1 mole of CaCO3

Whereas mole=mass/molar mass

molar mass of CaCO3= 40+12+48=100

therefore the moles =50/100 =0.5 moles

Hence the moles of the H2SO4 required to decompose the chalk=0.5moles

mass=molesx molar mass

therefore mass of H2SO4= 0.5x(2+32+64) = 49g

If 100% H2SO4 =49

then 60% H2SO4= 49x60/100 =29.4g.

Hence, Solved!
