Answer:
Petrified wood contains minerals that are only found in fossils.
Explanation:
learned it in school (promise)
Answer:
581 Joules.
Explanation:
Using the formula;
Q = m × c × ∆T
Where;
Q = amount of heat absorbed (J)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to the information provided in this question;
Q = ?
mass of ice = 15.9g
initial temperature = -4°C
final temperature = 14°C
Hence, ∆T = 14 - (-4) = 14 + 4 = 18°C
specific heat capacity (c) of ice in J/g°C = 2.03 J/g°C
Using Q = m × c × ∆T
Q = 15.9 × 2.03 × 18
Q = 32 × 18
Q = 581 Joules.
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.
