Answer:
A
Explanation:
if the earth slows down then that will give more time to the sun meaning days/nights will be longer
The balanced equation for the decomposition of solid lead iv oxide is as follows: 2PbO2 = 2PbO + O2.
Lead IV oxide decompose to give lead ll oxide and oxygen. Lead iv oxide is thermally unstable and it usually decomposes into oxygen and lead ll oxide when heated. Lead ll oxide is more stable than lead lV oxide.

Answer:
True
Explanation:
In an ionic reaction, the net ionic equation is used to calculate the standard enthalpy of reaction.
Hence the standard enthalpy of any ionic reaction can be obtained by considering its balanced net ionic reaction equation, hence the answer above.
