Explanation:
Hello there!
In this case, since perchloric acid is HClO4 and is a strong acid and calcium hypochlorite is Ca(ClO)2, the undergoing molecular chemical reaction turns out:
Thus, since the resulting hypochlorous acid is weak, it does not fully ionize, so it remains unionized, however, we can write the ions for the other species:
Now, we can cancel out the spectator ions, calcium and perchlorate, to obtain:
Best regards!

Answer:
Power,
No of bulbs = 78400000
Explanation:
We have,
Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, it mean it is mass per unit time i.e. m/t.
It falls from a height of 50 m
The gravitational potential energy of falling water is given by :
P = mgh
Power is equal to the work done divided by time taken. So,
So,
Let there are n bulbs that could power 15 W LED. It can be calculated by dividing the power by 15. So,
It means that the number of bulbs are 78400000.
Answer:
Magnesium + iron chloride → iron + magnesium chloride
Explanation:
It is the single replacement reaction.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Molecular equation:
Magnesium + iron chloride → iron + magnesium chloride
Chemical equation:
Mg(s) + FeCl₂(aq) → MgCl₂(aq) + Fe(s)
Ionic equation:
Mg(s) + Fe²⁺(aq) + 2Cl⁻(aq) → Mg²⁺(aq) + 2Cl⁻(aq) + Fe(s)
Net ionic equation:
Mg(s) + Fe²⁺(aq) → Fe(s) + Mg²⁺(aq)
