In the Bohr model, ____ electrons fill the first energy level, ____ electrons fill the second energy level, and ___ electrons fi

Setler [38]

The answer is d Thus, the first energy level holds 2 * 1^2 = 2 electrons, while the second holds 2 * 2^2 = 8 electrons. Each orbital. The third energy level can hold up to 18 electrons, meaning that it is not full when it has only electrons.

Equal amounts of methylene blue (319.85 g/mol) and potassium permanganate (158.034 g/mol) dyes were added to identical agar plat

tamaranim1 [39]

Answer:

Potassium permanganate.

Explanation:

Both substances are dyes, but the methylene blue has a bigger molecular mass (319.85 g/mol), that means that the particles are bigger in comparison with the potassium permanganate that has a molecular mass of 158.034 g/mol.

Since the molar mass is the half in the case of potassium permanganate, it can be considered that the particle size is the half in size. In the agar, a smaller particle will present less resistance to flow, that means that it going to move faster.

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.
