Answer:
Net force = 800 – 650
= 150 N
150 = (800 ÷ 9.8) a
a = 1470 ÷ 800
= 1.8375 m/s^2, downwards
The newton's second law is this:
F = M . A
Answer:
<u>Copper ( II ) chloride </u>
Explanation:
<em>According to the nomenclature , </em>
- <em>The metal ion name is followed by the non-metal ion</em>
- <em>The oxidation state of the metal is to be mentioned in the brackets .</em>
- <em>As
has two
ions , and the net charge on the compound is zero , the charge on copper is :</em>

thus ,
⇒
∴ ,
The proper nomenclature is :
Copper ( II ) chloride
