Answer:
B is a precipitation reaction.
Explanation:
This is because a precipitation reaction is when a solid is made from the combination of cations and anions in a solution to create a solid.
Answer:
i want to say nuclues but again i also think that it is electron shells
Answer:
C) 8
Explanation:
Total number of carbon atoms = 3
Number of single bonds = 3
So, each carbon is bonded to the next carbon with the single bond, Number of unshared electrons left with the terminate carbons are 3 and with the intermediate carbon is 2.
Thus, the two terminate carbon have 3 hydrogen each and the intermediate will have 2.
<u>Total - 8</u>
The general properties of Group 1 alkali metals are:
1. They form cations.
2. They are highly reactive.
3. They have a charge of +1.
4. They form ionic compounds.
5. When their oxides or hydroxides are reacted in water, they form alkalis i.e. bases.
6. They are usually soft in nature.
7. They have low densities.
Mg(s) + SnSO₄(aq) = MgSO₄(aq) + Sn(s)
Mg + Sn²⁺ + SO₄²⁻ = Mg²⁺ + SO₄²⁻ + Sn
Mg + Sn²⁺ = Mg²⁺ + Sn
