Answer:
31.Microbial
32.Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
33.examples to show that plastics are non corrosive in nature: Iron nails get rusted when exposed to moisture and air but plastic do not react with water and air. Plastic does not react with strong chemicals. Hence,cleansing chemicals are stored in plastic bottles and not in metal containers.
34.rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.
35.in an insect or amphibian) the process of transformation from an immature form to an adult form in two or more distinct stages.
38.a medical condition in which the lens of the eye becomes progressively opaque, resulting in blurred vision.

Answer:
D. 37 reports
Explanation:
Last month, he wrote 9 reports, and this month he wrote 28 reports. To find how many he wrote over the past two months, add his reports from last month and this month.
last month + this month
9 reports +28 reports
37 reports
So, he wrote 37 reports, or choice D
Explanation:
mass = desity × volume
volume = mass/density...
i believe thats right...
btw u means Physics formulae only..lol
The compound given (i.e. 3,3-dimethyl-1-butanol) is primary alcohol (1°) because the functional group (-OH) shows that it is alcohol is attached to a primary carbon (i.e terminal carbon).
The oxidation of all primary alcohols results in the formation of aliphatic aldehyde(also known as alkanal).
Suppose, it is secondary alcohol;
The oxidation of secondary alcohol results in the formation of ketone(also known as alkanone).
When 3,3-dimethyl-1-butanol undergoes oxidation, the suffix "ol" in the alcohol changes to "al"
Therefore, 3,3-dimethyl-1-butanol changes to 3,3-dimethyl-1-butanal after undergoing oxidation.
In conclusion, the product when 3,3-dimethyl-1-butanol undergoes oxidation is: 3,3-dimethylbutanal.
As such, option 2 is correct.
