Answer:
true
Explanation:
in order for the atom to be neutral the number of protons and electrons have to be the same.
It is rinsed with ionised water to remove any impurities that may be present
From the calculation, the molar mass of the solution is 141 g/mol.
<h3>What is the molar mass?</h3>
We know that;
ΔT = K m i
K = the freezing constant
m = molality of the solution
i = the Van't Hoft factor
The molality of the solution is obtained from;
m = ΔT/K i
m = 3.89/5.12 * 1
m = 0.76 m
Now;
0.76 = 26.7 /MM/0.250
0.76 = 26.7 /0.250MM
0.76 * 0.250MM = 26.7
MM= 26.7/0.76 * 0.250
MM = 141 g/mol

I am pretty sure it's true. I hope it is
Explanation:
Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. ... The fundamental principle of the science of chemistry is that the atoms of different elements can combine with one another to form chemical compounds.
