Answer:
B
Explanation:
sliver is being reduced (Ag+ + e‐ ----> Ag) while,
magnesium is being oxidized (Mg -----> Mg2+ + 2e‐)
False people can do whatever they want without people telling them what to do.
The new temperature of the piece of lead will be 37.5°C
SPECIFIC HEAT CAPACITY:
- The amount of heat absorbed or released by a substance can be calculated by using the following formula:
Q = m × c × ∆T
Where;
Q = quantity of heat absorbed or released (J)
m = mass of substance (g)
c = specific heat capacity
∆T = change in temperature (°C)
According to this question,
Q = 1.90J
m = 1.29g
T1 = 26°C
T2 = ?
c = 0.128 J/g°C
1.90 = 1.29 × 0.128 × (T2- 26°C)
1.90 = 0.165 (T2 - 26°C)
1.90 = 0.165T2 - 4.29
1.90 + 4.29 = 0.165T2
6.19 = 0.165T2
T2 = 37.5°C
Therefore, the new temperature of the piece of lead will be 37.5°C.

According to the research, fatty acids, which are long molecules in the form of a hydrocarbon chain, are a component of lipids.
<h3>What are lipids?</h3>
They are hydrophobic and water-insoluble molecules that are formed from the esterification of alcohols with fatty acids.
Lipids are a vital part of the diet of living beings since many vitamins are assimilated in the presence of certain lipids and many fatty acids are essential for animal metabolism.
Therefore, we can conclude that according to the research, fatty acids, which are long molecules in the form of a hydrocarbon chain, are a component of lipids.
