Thallium consists of 29.5%TI-203 and 70.5%TI-205. What is the relative atomic mass of thallium
Galina-37 [17]
To determine the relative atomic mass of thallium, we multiply the molar mass of the isotopes to their corresponding relative abundance. The molecular percentages should sum up to 1. In this case, we multiply 203 by 0.295 and 205 by 0.705 and add the answers of the two. The final atomic mass is 204.41 g/mol.

A well-insulated cup of water is too hot to make tea, so you mixed it with an equal amount of cool water to lower the temperatur
natulia [17]

Answer:

The entropy of the final solution decreases, as the reaction disorder is less.

Explanation:

The higher the temperature, the greater the heat of the reaction and the greater the disorder it has, so the entropy will increase ... But this is not the case, since the solution cools, decreasing the entropy proportionally.

In which species does nitrogen have an oxidation number of zero?
VARVARA [1.3K]
The most common species of nitrogen in which its oxidation state is zero is the diatomic nitrogen (N_{2}). This is because the oxidation number of pure elements (whether alone as an atom or combined with other atoms of the same element such as the diatomic nitrogen) is always zero. 

In addition to diatomic nitrogen, there are diazonium (R-N_{2}^{+}) compounds where nitrogen has an oxidation number of zero.
