HELP ASAP 20 POINTS
Colt1911 [192]

Solubility of a compound in water can be referred to as the amount of the compound that can be dissolved in 1 L of the solvent (water) at any given temperature. Solubility of a compound can be expressed in the units of g/L or mg/L.

Given that the solubility of calcium carbonate in water = 14 mg/L

We have to calculate the volume of water that can dissolve 11 g of calcium carbonate.

Converting 11 g calcium carbonate to mg:

11g *\frac{1000mg}{1g} =11,000 mg

Volume of water that would dissolve 11000 mg calcium carbonate

                             = 11000 mg CaCO_{3}*\frac{1L}{14 mg}

                             =785.7 L

Rounding the volume 785.7 L to two significant figures, we get 790 L water.

Therefore, we would need 790 L water to completely dissolve 11 g of calcium carbonate.

positive ions are smaller than the ions from which they are formed but negative ions are larger than the is from which they are
Vadim26 [7]
Positive ions are atoms that have lost an electron from its outtermost shell. It is positive because electrons are negative and the loss of something negative makes it a bit more positive.
A negative ion is larger than its original atom because it's gained an electron.

The more electrons an atomic has on its electron cloud, the bigger the atom.

Hopefully I didn't confuse you, good luck. ♡
