Answer:

When excess of carbon dioxide is passed in lime water, calcium carbonate is converted to calcium bicarbonate which is soluble, hence the milkiness due to calcium carbonate disappears.

Explanation:

Ca(OH)2+CO2 → CaCO3 (Milkiness) ↓+H2O

CaCO3+H2O+CO2 → Ca(HCO3)2 (soluble)

How are atoms related to balancing a chemical equation?
dmitriy555 [2]

Atoms are related to balancing equations because the amount of atoms on the left of the equation (reactants) needs to be the same amount on the right (products).

For example, 2H₂ + O₂ → 2H₂O

If you count the amount of hydrogen atoms on both sides each, there would be 4 (make sure to multiply the coefficient by the subscripts).

If you count the amount of oxygen atoms on both sides each, there will be 2 of them (2 in a molecule of oxygen)

I hope this helps and please mark me as brainliest!

Doss [256]

Answer: they don't have values there because they aren't on the pauling scale of electronegativity, as they don't form any compounds with other elements. However, argon and neon can technically form compounds with other elements; it is just extremely unlikely.
