Igneous rock that forms from magma that cools slowly within Earth’s crust is likely to have larger crystals and a coarse-grained texture.

Igneous rock that forms from lava that cools quickly on Earth’s surface is known as extrusive igneous rock. Another word for extrusive is volcanic.

Because the sample of igneous rock formed on Earth’s surface, it is extrusive. Because it’s composed of mostly light-colored minerals, it is likely felsic.

Because the sample of igneous rock formed within Earth’s crust, it is intrusive. Because it contains a very high concentration of dark-colored, high-density minerals, it is likely ultramafic.

The fact that gabbro is an igneous rock suggests that it was formed from the cooling and crystallization of magma. The fact that it is intrusive means that it formed within Earth’s crust. The fact that it’s mafic suggests that it contains a high concentration of dark-colored, high-density minerals.

Explanation:

1. Synthesis Reaction: In this type of reaction multiple reactant combine to form a single product.

2. Decomposition Reaction: In this type of reaction single compound or reactant break down into new elements or compounds.

3. Replacement Reaction: In this type of reaction an element replace an element in a compound.

4. Even hydrogen is not a metal but it can act as metal in single replacement reaction.

5. In combustion reaction fuel react with oxygen and give heat and light that increase temperature of surrounding.

6. In in-complete combustion reaction fuel react with in-sufficient oxygen and give carbon monoxide and carbon in form of soot.

7. Base is a compound that liberate OH⁻ ion in water.

8. indicators have different color in acid and base depends on pH of the solution

9. Salt and water are the product of neutralization reaction

NaOH + HCl = NaCl + H₂O

10. The pH of neutral solution is 7.
