Answer:
B sediment
Explanation:
The excess mileage leads to additional pollution. Car exhaust contains toxic gases, and car fluids often leak (oil drips, antifreeze leaks, etc...). The exhaust also contains nitrogen oxide, which can lead to nutrient-related problems in the environment.
Answer:
see explaination
Explanation:
We are given the (R)-3-bromo-2,3-dimethylpentane and asking to draw the curved arrow which is the showing the mechanism for first-order substitution and first-order elimination reactions. We know the formation of carbocation is the rate determining step in the first-order substitution and first-order elimination reactions.
So in the (R)-3-bromo-2,3-dimethylpentane there is –Br gets removed and formed the tertiary carbocation which is more stable, so the curved arrows in Box 1 to depict the flow of electrons and intermediate in Box 2.

Answer:
The answer is<u> NH3.
</u>
Explanation:
The N2H2 (O hydrazine) is formed when from the synthesis of ammonia and hydrogen peroxide.
Or also formed when a 1,000g sample of nitrogen is combined with a 7.2 x10∧-2 sample of hydrogen.
0.2160 of hydrogen is 3 times 7.2 x10∧-2.
It means that the compound would look like:
N2H6.
But in chemistry, if there are divisible numbers in a compound, they must be divided:
NH3.
The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
