Answer:
Explanation:
The main thing for this equation is to follow the amount on each side. Count each element on each side. Then by looking at the numbers figure out what numerical digit would make them equal.
For example:
On the left we have
Cu=1 and Cl=2.
But on the right we have
Cu=1 and Cl=3.
In order for them to be the same, we must add a coefficient of 3 to CuCl2 (aq0 on the left and a coefficient of 3 to Cu(s) on the right.

Answer: (4)
Explanation:-
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydronium ions
in water.
1. is a strong electrolyte and thus dissociate in water.
2. is a non electrolyte and thus do no dissociate in water.
3. is a strong electrolyte and thus dissociate in water.
4. is a weak electrolyte and thus partially dissociate in water.
Answer: Option (3) is the correct answer.
Explanation:
When a linear chain of carbon and hydrogen atoms is attached by single bonds only then it is known as alkane.
When a linear chain of carbon and hydrogen atoms contains a double bond then it is known as alkene.
When a linear chain of carbon and hydrogen atoms contains a triple bond then it is known as alkyne.
Therefore, in the given description there is a double bond between third and fourth carbon. Hence, the IUPAC name of given compound is 3-heptene.
