Answer is: mass of product is 649.35 g.
Balanced chemical reaction: Ca(s)+Cl₂<span>(g) → CaCl</span>₂<span>(s).
m(Ca) = 23.4 g.
n</span>(Ca) = m(Ca) ÷ M(Ca).
n(Ca) = 23.4 g ÷ 40 g/mol.
n(Ca) = 0.585 mol.
From chemical reaction: n(Ca) : n(CaCl₂) = 1 : 1.
n(CaCl₂) = 0.585 mol.
m(CaCl₂) = 0.585 mol · 111 g/mol.
m(CaCl₂) = 649.35 g.
Work can transfer entertainment between objects and cause a change in the amount of total energy. Work can also transfer energy between objects and cause a change in the form of energy .
The correct answer is: -3 (minus three)
Explanation:
To find the overall charge, we add electrons and protons. Make sure that you use the negative sign for an electron and positive sign for proton.
There are 10 electrons. It means the charge is "-10"
There are 7 protons. It means the charge is "+7"
Add both of them:
+7 - 10 = -3
Therefore the overall charge on this ion is -3.
