Sodium Oxide ---> Na2O
Calcium Chloride ---> CaCl2
Potassium Sulfide ---> K2S.
I hope this helps! :)
Answer:
Small marine animals produce a very hard skeleton made of calcium carbonate, which they extract from the seawater and combine CO2 for limestone.

Answer:
2.28 atm
Explanation:
V₁ = 2.33L, V₂ = 1.08L
T₁ = 289K, T₂ = 304K
P₁ = 1.05 atm, P₂ = ?
Where V₁ and V₂ are initial and final volume respectively
T₁ and T₂ are initial and final temperature respectively
P₁ and P₂ are initial and final pressure respectively
The formula to be used here is the general gas equation:
P₁V₁/T₁=P₂V₂/T₂
1.05 × 2.23/289 = P₂ × 1.08/304
P₂ × 1.08 × 289 = 1.05 × 2.23 × 304
P₂ = (1.05 × 2.23 ×304) ÷ (1.08 × 289)
P₂ = 711.82 ÷ 312.12
P₂ = 2.28 atm
<h3><u>Kupier Belt:</u></h3>
<u>Location:</u>
Kuiper belt also known as Edgeworth-Kuiper belt which is in the shape of "flat ring of icy small bodies" that revolve around the Sun beyond the orbit of the planet Neptune. It is a "circumstellar disc" that is similar to the "asteroid belt" in the outer solar system.
<u>Composition: </u>
Its composition mainly consists of "small bodies or remnants" from the time when the solar system was formed. It also consists of frozen volatiles (termed "ices"), such as "methane, ammonia, and water".
<u>Relationship to dwarf planets:</u>
This belt is also a home to the dwarf planets such as "Pluto, Haumea, and Makemake".
Thin layer chromatography(TLC) works with the principle of separation through adsorption.
It is used in the isolation and extraction of lipids through the following steps:
- apply the lipid samples spots in the bottom of the plate.
- also apply sample solution to the marked spot
- pour the mobile phase into the TLC chamber and use a moist filter paper to cover it. this is done to maintain equal humidity.
- then place the plate in the TLC chamber and close it with a lid.
- the plate is immersed into the solvent (mobile phase) for its development. this is done, keeping in mind that the sample spot should be above the solvent.
- once the sample spots are developed, they are removed and dried.
- this is later viewed using the UV light chamber to see the isolation of the lipid sample.
