Answer:
The answer to your question is: letter b Sulphur
Explanation:
Remember that in neutral molecules the sum of the oxidation numbers equals zero.
Mg⁺²S⁺⁶O⁻²₄
Magnesium = +2
Sulphur = +6
Oxygen = -2 x 4 = -8
Answer:
Explanation:
The human body is constantly radiating heat to its surroundings, and human comfort is closely tied to the rate of this radiation we need to know this because its part of a daily life.
Answer:
Not likely
Explanation:
It would only be likely if the humidity was high enough to rain.
so, it is not likely
The elements are identified by the number of protons of the atom, which is its atomic number.
In this case the number of protons 39 (atomic number 39) permit you to identify the element as gallium.
Now, to identify the isotope you tell the name of the element and add the mass number.
The mass number is the sum of the protons and the neutrons
In this case, the number of neutrons is the original 39 plus the 2 added suddenly, i.e. 39 + 2 = 41, so the mass number is 31 + 41 = 72
Therefore, the isotope is gallium - 72.
Answer: isotope gallium - 72
