Your answer is AIDS good luck
Answer:
CaCl
2
Explanation:
As with all these problems, we assume a
100
⋅
g
of compound, and divide through by the ATOMIC masses of each component element:
Moles of calcium
=
36.1
⋅
g
40.08
⋅
g
⋅
mol

=

Moles of chlorine
=
63.9
⋅
g
35.45
⋅

.
We divide each molar quantity through by the smallest molar quantity (that of calcium) to give an empirical formula of
CaCl
2
.
For ionic materials, we do not speak of the molecular formula, and the empirical formula is the formula we quote for reference.
It’s called neutralization. The alkali has neutralized the acid by taking away the H+ ions and then turning them into water.
