The percent error of Chemistry student : 7.4%
<h3>
Further explanation
</h3>
Given
40 °C measurement
Required
The percent error
Solution
% Error : difference between the theoretical value and the actual value
or
% Error : Absolute Error / Accepted Value
Absolute Error = Measured Value - Accepted Value
% Error for Chemistry student :
1. Subtract the measurement value with the accepted value
= 40 °C - 43.2 °C
= -3.2 °C
2. Divide by the accepted value, and multiply by 100
= |-3.2/43.2| x 100%
= 7.4%
Answer:
Hydride ion
Explanation:
You often see the reduction with NADH written as
NADH ⟶ NAD⁺ + H⁺ + 2e⁻
If you think about it, H⁺ + 2e⁻ is equivalent to H:⁻, so we could write the reaction as
NADH ⟶ NAD⁺ + H:⁻
In terms of a mechanism, the dihydropyridine ring of NADH transfers a hydrogen atom with its pair of electrons (a hydride ion) to the substrate and becomes the more stable, aromatic pyridinium ion in NAD⁺.

Answer: Water inside the seed coat creating a pushing force, breaking the seed coat.
Explanation:
Seed germination can be defined as the process by which a new plant emerge out from a seed. The radicle is the first emerging part from a seed and it develops into a root and the plumule is the second emerging part and it develops into a shoot. The light, water, adequate temperature, and soil are the factors that are necessary for seed germination.
According to a given situation, the popcorn kernel will receive the moisture necessary for the germination process, the water will imbibe into the seed coat creating pressure inside the seed and which will cause the seed coat to break and the new plant parts or seedling will emerge out of the seed coat.
