In this item, we are instructed that the copper ion is to be reacted with the ion of the chlorine. The ion for copper is positively charged (cation) because it has to lose some of its electron in order to achieve stability. As the charge suggests, the number of electrons is 2.
The counterion (anion) is the chloride which can be written as Cl⁻¹. Since the charge of Cl is only -1, two of this anion should be allowed to react with Cu²⁺ so that the formed molecule is neutral. The formula is therefore CuCl₂.
<em>ANSWER: CuCl₂</em>
Answer:
Calcium sulphate CaSO4 is a naturally occurring calcium salt . it is commonly known in it's dehydrated form , CaSO4 , 2H2O , a white or colourless powder called gypsum . Hydrated calcium sulphate {CaSO4 × H2O } countians 21% ( by mass) of water of crystalization i.e. it's hydrated form is CA= 40 S= 32 O= 16 H=1

<h3>Answer :</h3>
<h3>Specific Heat</h3>
<h3>Explanation :</h3>
<h3>The specific heat represents the amount of energy required to raise 1 kg of substance by 1oC (or 1 K), and can be thought of as the ability to absorb heat. The SI units of specific heats are J/kgK (kJ/kgoC). Water has a large specific heat of 4.19 kJ/kgoC compared to many other fluids and materials.</h3>
