Answer:
D. It has a fine-grained texture.
Explanation:
Lava cools and solidifies before crystals can grow very large causing a fine-grained texture on extrusive igneous rock.

The soft ionization technique that uses a UV-absorbing compound upon which the analyte of interest is placed and eventually vaporized into a plume of ions directed into the mass analyzer is matrix-assisted laser desorption ionization.
<h3>
What is Soft ionization technique ?</h3>
Soft Ionizer produces less fragment ions. Soft ionizer produce the molecular ions or a quasi molecular ion. This technique not fragment the macromolecules into the more smaller charged particles.
Thus from the above conclusion we can say that The soft ionization technique that uses a UV-absorbing compound upon which the analyte of interest is placed and eventually vaporized into a plume of ions directed into the mass analyzer is matrix-assisted laser desorption ionization.

Explanation:
because there are 4 Iodines on the left, we'll put. 4 in front of NaI to balance it. This would result in 4 Na on the left, so we'll put a 2 in front of Sodium Sulfate to balance the right side. Now we have 4 Na and I on both side, as well as 2 Sulfate on both sides. Pb is already balanced. The equation is now complete.
Answer:
a) significant figures b) decimal places
Multiplying/dividing ex: 1.33 * 4.4932 = 5.98 because the first component only has three sig figs while the second has five.
Adding/subtracting ex: 12.13 + 53.5763 = 65.71 we ignore the whole numbers and focus only on the decimal places. The first component only has two while the second has four. Hope this helps!
