Determine the correct name for the compound, mg3n2. a) manganese nitride b) magnesium nitride eliminate c) magnesium (ii) nitride d) trimagnesium dinitride

Answer : The correct option is, (B) Magnesium nitride

Explanation :

is an ionic compound because magnesium element is a metal and nitrogen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

The naming of ionic compounds is given by :

Cation is written first. The anion is written next and a suffix is added at the end of the anion. The suffix written is '-ide'.

Thus, the name of is magnesium nitride.

Therefore, the correct option is, (B) Magnesium nitride

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
