Water, because electrolysis is using electricity to break the bond of water to release 2 Hydrogens and the 1 Oxygen.
The best answer among the following choices would be A) since the other options are NOT nonrenewable energy sources.
The balanced chemical equation Lead IV oxide decomposes
to yield lead II oxide and a colorless gas is
Pb3O4 → 3PbO + 1/2O2(g). The key in the balancing of
chemical reaction is to make sure that you got the exact chemical formula of
the substance that is reacting and the yielded product. After getting the
formula, identify first the hardest element/atom to be balanced such as Na, Zn,
Cl, etc. Then proceed to the easier ones such as O, H. Make sure to not the
atoms present in the molecule of the substance.
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
</span><span>7.3x10^-3 g of CaSO4 ( 1 mol / 136.14 g ) = 5.36x10^6-5 moles
</span> 5.36x10^6-5 moles ( 6.022 x 10^23 formula units / mole ) = 3.23x10^19 formula units
