The best description of Ernest Rutherford's experiment is letter C. The positively charged particles were fired through a gold foil. Most of these particles went right through, while others bounced back. This experiment led to the discovery of the nucleus.
The motivation to abstain from adding water to concentrated acids is that, with a few acids, amid weakening, a considerable measure of warmth is discharged, by adding the corrosive to the water, the generally extensive measure of water will retain the warmth. On the off chance that you added water to concentrated corrosive when you initially beginning pouring the water, it could get sufficiently hot for the little measure of water that was filled all of a sudden bubble and splatter corrosive on you. Concentrated sulfuric corrosive is most famous for doing this, not all acids get that hot on weakening, but rather in the event that you make a propensity for continually adding the corrosive to water for every one of them, you can't turn out badly.
The actual number of atoms of each element present in the molecule of the compound is represented by the formula known as molecular formula.
Molar mass of the unknown compound = 223.94 g/mol (given)
Mass of each element present in the unknown compound is determined as:
- Mass of carbon,
:
- Mass of hydrogen,
:
- Mass of chlorine,
:
Now, the number of each element in the unknown compound is determined by the formula:
- Number of moles of :
- Number of moles of :
- Number of moles of
Dividing each mole with the smallest number of mole, to determine the empirical formula:
Multiplying with 2 to convert the numbers in formula into a whole number:
So, the empirical formula is 
.
Empirical mass = 
In order to determine the molecular formula:
n = 
n = 
So, the molecular formula is:
