Answer:
The correct answer is KNO3
Explanation:
Pb(NO3)2 +2 KCl -> PbCl2 + KNO3
If we look at the left side of the equation we could see that there are 1 lead atom, 2 nitrate atoms ,2 potassium atoms and 2 chlorine atoms
Now when we look at the right side of the equation, we found that there are –
1 lead atom and 2 chlorine atoms (PbCl2) , thus lead and chlorine are balanced as they have the same number of atom in LHS and RHS
There is only 1 potassium and 1 nitrate atom on RHS , thus KNO3 is not balanced.
The balanced equation would be –
Pb(NO3)2 +2 KCl -> PbCl2 +2 KNO3
The atomic number for oxygen is 8.
Sharks need to be protect, if they weren’t the ecosystem would not do good. If the sharks weren’t there to eat the fish and other food then the fish population would grow. If the fish population grow then the seaweed and algae population would go down because the fish would eat it all. That is why sharks need to be protected.
