Answer:
It is written exactly like that; Mg3N2
Explanation:
Roman numerals are used sometimes to show the charge of an ion that can be multiple charges.
Answer:
The correct answer is - valid.
Explanation:
In this case, there is consistency in the results measures in the experiment which makes this method reliable. The consistency of a measure is referred to the reliability.
It is also given that the level of contamination of individual containers as per the average parameter of the contamination of large containers which makes this method not valid as the measurement method is how correctly it measures the true value of the parameter.
Thus, the correct answer is - method is reliable, but not valid.
Nuclear fission is a process by which the nucleus of an atom is split into two or more smaller nuclei, known as fission products. The fission of heavy elements is an exothermic reaction, and huge amounts of energy are released in the process.
Answer:
(i) +3.
(ii) Mn.
Explanation:
Hello,
(i)
Based on the diatomic ion, we solve for the unknown oxidation state of carbon, assuming that the oxygen works with -2, by a change balance:
(ii)
We first must each ion's oxidation states as follows:
Then, for the reduction half reaction we identify the manganese as the element decreasing its oxidation state based on:
In addition, the carbon is oxidized from +3 to +4 (increase the oxidation state).
Kind regards.
