Answer is: d. Mg3N2.

Mg₃N₂ is magnesium nitride.

Nitrogen (nonmetal) in this chemical compound has oxidation number -3 and magnesium (metal) has oxidation number +2.

Smallest common multiple for 3 and 2 is 6.

number of nitrogen atoms = 6 ÷ 3.

number of nitrogen atoms = 2, there are two nitrogen atoms.

number of magnesium atoms: 6 ÷ 2.

number of magnesium atoms = 3.

Deffense [45]

Answer:

V=23.5L

Explanation:

Hello,

In this case, it is convenient to compute the car's mileage in km/L as follows:

25.0\frac{mi}{gal}*\frac{1km}{0.6214mi}*\frac{1gal}{3.78L}=10.64\frac{km}{L}

In such a way, since the distance is measured to be 250 km, the volume requirement is:

V=\frac{250km}{10.64kg/L}\\ \\V=23.5L

Regards.

valkas [14]

Answer:

Option B - reducing; NADH; negative

explanation:

Nicotinamide adenine dinucleotide, or NADH, is a compound, that's more actively used in the transportation of electron chain. It's evident that produced and make use NADH than FADH2 in the process that brings about energy creation.

NADH carries electrons from one reaction to another. Its Cofactor is in two forms in cells: NAD+ accepts electron from other molecule and hence reduced as an oxidizing agent while NADH is formed by this reaction, which can be used to donate electrons because it's a reducing agent. The main function of NAD is to transfer these reactions.

Leni [432]

The correct answer is - mutualistic symbiotic relationship.

The mutualistic symbiotic relationship is a relationship between two or more species, in which they collaborate and have mutual benefit of their collaboration.

In this case, the pseudomyrmex ants and the acacia trees do exactly that, they collaborate for the benefit of both of them. The acacia tress provide shelter, nectar, and protein for the ants, and the ants are protecting the tree from herbivorous insects and parasitic plants. In this way, both of them benefit from each other.
