<h3>What is a chemical formula?</h3>
A chemical formula is used to show the number and type of atoms present in a molecule, using the atomic symbols of the elements and numerical subscripts.
From the chemical formula;
We can deduce that we have the following elements and their corresponding number of atoms in one molecule of the compound;
Carbon = 1 atom
Hydrogen = 1 atom
Chlorine = 3 atoms
So, in 5 molecules of the compound;
Carbon = 1 x 5 = 5 atoms
Hydrogen = 1 x 5 = atoms
Chlorine = 3 x 5 atoms = 15 atoms
In conclusion, from the solution above, we can say that we have 5 atoms of carbon present in 5 molecules of
.

Answer:
Time use of cellphone times 3 hours before sleep.
Explanation:
It is scientifically proven that cell-phone use before bed can disturb your sleep. The blue light can cause your brain to release chemicals that associate with staying awake or even waking up. So measure the hours or minutes you use your phone 3 hours before you go to sleep.
Since gas is sealed in container, volume of gas will ramain constant. from ideal gas equation PV=nRT, P/T = nR/V ==> P/T = constant.( constant since v is constant so whole term must be constant). therefore, (P/T)1 = (P/T)2.==> 50/300 = P2/360. ==> P2= 50X360/300 = 60KPa. Hope this helps
