Answer:
Hi
2-methyl-1-propanetiol is found in alcoholic beverages. It is a food additive, and is also found in guava, milk, cooked beef, cooked pork and beer. It is also used as a flavoring. A dose of 7168 mg / kg produces muscle weakness, ataxia, cyanosis. An intraperitoneal dose of 917 mg / kg can cause nervousness and a feeling of spastic paralysis. In the attached file is the scheme.

Answer:
Thomson's results showed that atoms contain smaller particles, so Dalton's theory had to be modified. Rutherford's results showed that most of an atom is empty space and that the mass is concentrated in the center of the atom.

To solve this question, we first need to know the mass of one mole of mercury. This can be done by checking the periodic table.
From the periodic table, we can see that:
molar mass of mercury = 200.59 grams/mole.
From the measurements, the chemist found that the participated amount of mercury is 0.02 moles.
We can simply determine the mass of 0.02 moles by doing cross multiplication as follows:
mass of 0.02 moles = (0.02 x 200.59) / 1 = 4.0118 grams
Rounding the answer to 2 significant digits, we get:
mass of 0.02 moles = 4.01 grams
Answer:
C. Solid in liquid
Explanation:
Seawater is an example of a solid in liquid solution.
Sea water is made up of:
- water
- mineral salts
- dissolved gases
A liquid solution is always made up of a solute being dispersed within the solvent medium.
The solvent is the liquid or fluid medium.
Such solutions are homogeneous because the solute particles are distributed evenly or uniformly in the solvent.
The solute is usually present in smaller amount compared to the solvent.
