The answer is True, those items are essential for working with hazardous chemicals.
Answer:
(√ 20) hbar.
Explanation:
The first thing to do is to calculate the second principal quantum number, n from the formula for Calculating energy,E and this is done as given below;
Energy, E = 13.6 (1 / n^2 - 1/6).
(Where energy,E = 1240/ 7474).
Hence, when we solve the above equation for n, the principal quantum number = 5.
We know that the azimuthal quantum Number, l = (n- 1); 5 - 1 = 4.
Therefore, the maximum possible magnitude of the orbital angular momentum of the atom after emission = (√ 4 × 5) hbar.
the maximum possible magnitude of the orbital angular momentum of the atom after emission = (√ 20) hbar.
Note that hbar = 1.0545718 × 10-34 m2 kg / s.
Answer:
Allows for a quick "doubling of population because they skip pollination and fertilisation. There is less energy required for asexual reproduction. Large colonies can form that out complete the other organisms for nutrients and water. ... Sexual reproduction leads to genetic variation in new generations of offspring.

Answer:
Although all organic compounds contain carbon, and almost all have hydrogen, most of them contain other elements as well. The most common other elements in organic compounds are oxygen, nitrogen, sulfur, and the halogens.
