Answer: natural gas, air, carbon based fossil fuel, coal. They provide a living space for all humans and animals. Help our environment.
Explanation:
Answer:
615ml
Explanation:
Vol(ml) = (gms solute)/[(Molar Answer => Conc)(formula Wt solute))] = (100g)/{(1.4M)(116g/mol)} = 0.615L = 615ml.
Answer:
30 °C
Explanation:
When you pour water from one glass to the other, the heat energy will flow from the hot water to the cold.
You have equal masses of water in each glass. The hot water should cool down as much as the cold water warms up.
The final temperature should be halfway between the starting temperatures in each glass.
(10 °C + 50°C)/2 = 60 °C/2 = 30°C
The temperature of the full glass of water should be 30 °C.
Answer:
Explanation:
The objective of this experiment is to match the expected result with each of the propositions given after the experiment had been carried out.
1. The top layer was the <u>organic </u> layer. This is because all the organic compounds have lesser density than water except chloroform that will be formed when NaOH is added.
2. 9-fluorenone was most soluble in the <u>organic </u>layer. This is so as a result of its non-polar carbon structure.
3. Deprotonated chloroanilic acid was most soluble in the <u>aqueous </u>layer as a result of the formation of an electrovalent bond with water.
4. The bottom layer was the <u>aqueous </u>layer as a result of the huge amount of water density.
5. The organic layer was a <u>yellow</u> colored solution.
6. The aqueous layer turned into a <u>pink</u><u> </u> colored solution.
