Igneous, they form cooling magma deep inside the earth. They often have large crystals. Metamorphic; they are formed through the change of igneous and sedimentary rocks. They can form both underground and at earths surface.

Explanation:
Hello,
In this case, since the Lewis theory is based on the bonds formation between atoms via the valence electrons, we can verify the chemical formula of the compound formed by strontium and nitrogen by noticing that strontium has two valence electrons as it is in group IIA, for that reason, two nitrogens should be available for bonding. Therefore, since nitrogen is in group VA, it is said that three electrons are required to attain the octet (maximum amount bonded electrons), for that reason, three strontiums are should be available for bonding. In such a way, the formula should be:

Explanation:
All atoms of one type were identical in mass and properties.
Precipitate is silver sulfate and the net ionic equation is
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
<u>Explanation:</u>
The given reaction is the reaction of sodium sulfate with silver nitrate and as the reaction goes we will get the precipitate of Silver sulfate and the balanced reaction is given as,
Na₂SO₄ + 2 AgNO₃→ Ag₂SO₄↓ + 2 NaNO₃
Here silver sulfate is obtained as a precipitate.
Net ionic equation is the equation in which the ions involved in the reaction only taken into account that is ions forming precipitate, whereas the other ions are considered as spectator ions, ions do not involved in the reaction.
Here the net ionic equation is:
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
