Explanation:
As you can that water splits into molecules of hydrogen and 1 molecules of oxygen since , number of molecules of hydrogen released is double the number of molecules of oxygen released, volume occupied by hydrogen gas is double the volume occupied by oxygen gas
Explanation:
Fluorine: F-
Aluminium: Al3+
Bromine: Br-
3F2 + 2AlBr3 => 3Br2 + 2AlF3
Answer:
1. Hyphothesis 2.Theory 3. law
Explanation:
not sure, but law is observation, theory is based on knowledge things before.
Explanation:
Lone pairs are present on nitrogen atoms of both pyridine and pyrrole.
In pyrrole, the electron pair on nitrogen is involved in resonance and hence does not available for bonding. Therefore, pyrrole does not possess basic character and remains unreactive towards HCl.
In case of pyridine, as 6 pi electrons are present in the ring, so, electron pair of nitrogen does not participate in resonance. So, because of presence of lone pair, pyridine possess basic character and hence, reacts readily reacts with HCl.
Balanced chemical reaction: 3Mg + 2Fe(NO₃)₃ → 2Fe + 3Mg(NO₃)₂.
Oxidation number of iron in iron(III) nitrate is +3, oxidation number of magnesium in magnesium nitrate is +2.
The reactivity
series<span> is
a series of metals from highest to lowest reactivity. Metal higher in the
reactivity series will displace another, magnesium is more reactive than iron.</span>
