Answer:
True
Explanation:
You must first observe your data then form a hypothesis.
I assume there is a typo in the equation. It is H2O instead of H2I.
The ratio of H2 and O2 that react with each other is 2:1. To find out the grams of H2, we need to first find out the moles of O2 and H2.
Moles of O2 = mass of O2/molar mass of O2 = 192g/32g/mol = 6 mol. Therefore, the moles of H2 = 6mol *2 = 12 mol.
So the mass of H2 that reacts with O2 = moles of H2 * molar mass of H2 = 12 mol * 2 g/mol = 24 g
Answer:-
+1
Explanation:-
Group 1 A compounds has 1 valence electron.
According to the octet rule, if outermost shell has 8 electrons then it is stable.
So Group 1 A compounds lose 1 electron to fulfill octet.
Oxidation number is the number of electrons lost or gained. It is positive if electrons are lost and negative if electrons are gained.
Hence the oxidation number of group 1 A compounds is +1.
