Which of the following metals (M) will form an ionic compound with nitrogen with the general formula M3N2?

2 answers:

I thinks it’s D since Be has a charge of 2+ and you are given the formula of M3N2. When you swap and drop the charge of N (3-) and the charge of Be (2+) you get M3N2

The Texas high plains region does not revive much rain. It is reasonable to predict that this region, compared to other ecoregio

Answer:

Less soil erosion

Explanation:

Due to the low amount of rainfall in this region, it is easier to say that the region compared to other ecoregion will suffer less soil erosion.

Erosion is usually the washing away of the top layer of the soil. Rainfall is one of the most important element that causes erosion. Surface runoff for an extended period of time can remove the topmost layer of the earth on which plant can grow. This starves the soil of its rich nutrients and minerals.

Determine the oxidation state of nitrogen in lino3.

Andre45 [30]

Answer : The oxidation state of nitrogen in $LiNO_3$ is, (+5)

Explanation :

Rules for the oxidation numbers :

The oxidation number of a free element is always be zero.
The oxidation number of a monatomic ion equal to the charge of the ion.
The oxidation number of Hydrogen (H) is +1.
The oxidation number of oxygen (O) in compounds is usually -2, but it is -1 in the peroxides.
The oxidation number of a Group 1 element in a compound is +1.
The oxidation number of a Group 2 element in a compound is +2.
The oxidation number of a Group 17 element in a binary compound is -1.
The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.

The given compound is, $LiNO_3$

Let the oxidation state of 'N' be, 'x'

$(+1)+x+3(-2)=0\\\\x=+5$

Hence, the oxidation state of N is, (+5)
