Answer:

B) Ethanol must act as a competitive inhibitor for the alcohol dehydrogenase and therefore slows the formation of formaldehyde.

Explanation:

An inhibitor is a substance that binds to an enzime and prevents it to react with a substrate. In this case, the inhibitor is ethanol, binding to the enzime (alcohol dehydrogenase) and preventing it to react with methanol and thus from it form the toxic formaldehyde.

A competitive inhibitor has a similar structure to the substrate, that is why it binds to the same active site. In this case, ethanol has a similar structure to methanol, which is why the answer is B and not A.

Which equation represents a neutralization reaction?

Harrizon [31]

Answer: HCI + KOH → KCI + H20

Explanation:

HCI(aq) + KOH(aq) → KCI(aq) + H20(l)

Acid + base → Salt + Water.

The above is a neutralization reaction in which an acid, aqeous HCl reacts completely with an appropriate amount of a base, aqueous KOH to produce salt, aqueous KCl and water, liquid H2O only.

This is a neutralization reaction since, the hydrogen ion, H+, from the HCl is neutralized by the hydroxide ion, OH-, from the KOH to form the water molecule, H2O and salt, KCl only.

Anuta_ua [19.1K]

Answer:

A full moon occurs when the Moon appears as a complete circle in the sky.

- The moon shows no visible light of its own, so we only see the parts of the moon that are lit up by other objects.

Answer:

Magnetism is believed to be caused by the alignment of small, numerous sub-units called : Domains

Explanation:

Domains : A magnetic domain is the region in which in which magnetic field of the atoms are grouped together and aligned.

In unmagnetized material all the magnetic Domains point in different direction.

In magnetised material (ferromagnets , antiferromagnets) , The Domains point in a particular( fixed Pattern) direction.

In case of accidental contact with chemicals, how long should the eyes be flushed at the eyewash station

FromTheMoon [43]

Answer:

See the answer below

Explanation:

The duration of flushing the eyes at the eyewash station in case of accidental contact with chemicals depends of the nature of the chemical.

If the chemical is known to be a non-irritant or mild-irritant one, a 5-minute washing time is recommended as the first aid. before seeking the help of a physician,

For moderate to severe irritant chemicals, an immediate 15-20 minutes washing period is recommended before seeking further medical help.

For corrosive and strong alkalis chemicals, 30 and 60 minutes washing are recommended respectively before seeking the attention of a physician.

However, if the nature of the chemical is unknown, a minimum of 20-minutes washing is generally recommended as first aid before seeking immediate medical help.
