Electrons are like that in a wire. If one moves they all have to move. Thus when you turn on a switch an electrical potential difference (created by a generator) immediately causes a force that tries to move the electrons.
Answer:
co2 was water because 2 co will made water
Explanation:
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>
