Complete and balance the following equations,
1. Li + 12 →
2. Mg + N2 -
3. SO3 + H2O →
4. Sr+ 5 →
5. Mg + O2 →
6. Sulfur trioxide gas is bubbled through water,
7. A hot piece of magnesium ribbon is added to an atmosphere of chlorine
gas.
8. Carbon dioxide gas is bubbled through water.
9. Barium oxide is added to water.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
