H20 = 2.741 x 10^23
C6H8 = 1.0823 x 10^23
The others are wrong it's B. Condensation
It is a physical change because you can not put it back like it was
<h3><u>Answer</u>;</h3>
B. 3/2
<h3><u> Explanation;</u></h3>
Balance the chemical equation
2Al + 3Cl2 → 2AlCl3
We want to convert moles of AlCl3 to moles of Cl2
The conversion factor is 2 mol AlCl3/3 mol Cl2.
We choose the one that makes the units cancel:
x mol AlCl3 x (3 mol Cl3)/(2mol AlCl3) = x mol Al
The fraction for the molar ratio is 3/2.
it will sink
Explanation:
the solid iron will sink because it is dense than the liquid iron I will sink and it will melt
