Answer:
Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

Answer:
Explanation:
First we find the Molecular weight of CaCl2
looking at the periodic table the MW of Ca is 40.078 and Cl is 35.453 and the ratio of ca to cl is 1:2 so we multiply cl by 2 which is 35.453*2=70.906
we add them together: 40.078 + 70.906 = 110.984 g/mol
now:
* 3.45 mol
the mol cancels out and we left with 3.45 * 110.984 grams = 382.89 grams
The physical characteristics ofminerals include traits which are used to identify and describe mineralspecies. These traits include color, streak, luster, density, hardness, cleavage, fracture, tenacity, and crystal habit.
Thus the molarity is inversely proportional to the volume which means if we increase the volume value of the molarity decreases whereas if we decrease the volume the concentration or molarity would be increased. So the greater the volume lower the concentration of the solution.
