The 2 trends that are commonly seen in modern concentration
chart , first it is increasing. Since the star of industrial revolution the
amount of co2 increases with time. The second trend is that the temperature
also increases because it is a green house gas which causes the global warming.
Don't all halogens have 8 valence electrons? They don't need to gain or lose any because they are already stable.
Answer:
CaCl₂ + CuSO₄ → CaSO₄ + CuCl₂.
Explanation:
- It is a replacement reaction, that cations and anions are replaced with each other.
So, it gives CaSO₄ and CuCl₂.
- To balance the reaction, we apply the law of conversation of mass, that the no. of atoms in the reactants side is equal to that in the products side.
So, the balanced reaction is:
<em>CaCl₂ + CuSO₄ → CaSO₄ + CuCl₂.</em>
