Answer:
Number of mole = 13.155moles
Explanation:
One mole of a substance is equal to 6.022 * 10^23 units of that substance.
Mole of a substance can be defined according to chemistry as the mass of substance containing the same number of fundamental units
Using the formula for mole
n = m/Mm
n = number of mole
m = number of mass
Mm = number of molar mass
We are provided with some information
Given: mass of carbon to be 158g
Molar mass of C = 12.0107g/mol
Using the formula
n = m/Mm
n = 158 / 12.0107
n = 13.155 moles
Answer:
The test solution is acidified using a few drops of dilute nitric acid, and then a few drops of silver nitrate solution are added. Different coloured silver halide precipitates form, depending on the halide ions present: ... iodide ions give a yellow precipitate of silver iodide.
Because gravity is trying to pull it down not up and when it's going down it's going with gravity not against it.
The exception to the rule concerning the solubility of chlorides in water is PbCl2.
The solubility rules give us an idea of which substances are soluble in water and what substances are not soluble in water. According to the solubility rules, chlorides are soluble in water.
However, chlorides of lead are not soluble in water hence, the exception to the rule is PbCl2.
