The total hours that are necessary to reduce carbon dioxide level to at least 325 ppm are 4 hours.
<h3>How does carbon dioxide concentration change over time?</h3>
First hour:
- 1,100 - 20 %
- 1,100 - 220 = 880
Second hour:
- 704 - 20%
- 704 - 140.8 =663.2
- 663.2 - 20%
- 663.2 - 132.64 = 530.56
Third hour:
- 530.56 - 20%
- 530.56 - 106.112 = 424.44
- 424.44 - 20%
- 424.44 - 84.88 = 339.55
Fourth hour:
- 339.55 - 20%
- 339.55 - 67.91 = 271.64

Answer:
its determined by the size of inside the cup
Answer:
hypoeutectoid
Explanation:
ferrite: pure form of iron
cementite: It is iron carbide with 93.3% iron and 6.67% carbon
hypoeutectoid: Eutectoid steel with carbon fraction less than 0.8%
hypereutectoid: Eutectoid Steel with carbon content more than 0.8%
For the mentioned iron-carbide alloy,
% of carbon in iron-carbide alloy= percentage of cementite × percentage of carbon in cementite
% of carbon in iron-carbide alloy= 0.09× 0.0667
= 0.6%
so the alloy is hypoeutectoid
Answer:
The correct option is B.
