Lewis structure for nitrogen triiodide, NI(3)

Rasek [7]

Answer:

Lewis structure for nitrogen triiodide, $NI_3$ is given in the attachment.

Explanation:

Given:

The given compound is Nitrogen triiodide. In which 1 atom of Nitrogen combines with 3 atoms of Iodine. Both Nitrogen and Iodine are non-metals,So they form covalent bond by sharing of electrons.

The electron configuration of Nitrogen and Iodine is given below;

$N(7) = 1s^2,2s^22p^3\\I(53) = 1s^2,2s^22p^6,3s^23p^63d^{10},4s^24p^64d^{10},5s^25p^5$

There are 5 electrons in valance shell of Nitrogen atom and 7 electrons in valance shell of Iodine atom.

So, 3 atom of Iodine shares 1 electron with 1 electrons of Nitrogen.

The Lewis dot Structure is in the attachment.

Which type of river is similar to a mature river, but flows more slowly so has less power to change the landscape? Select one: a

Ede4ka [16]

Answer:

The correct option is;

C. Old Age River

Explanation:

Among the three stages of the development of a river, which are the youthful, mature, and old age stages, the old age river is least dynamic

The water is very slow moving with a low gradient and lesser erosive power to alter the landscape which results in the appearance of flood planes

Examples of old age rivers include, lower Ganges, lower Nile, Indus, and Yellow rivers

Old age rivers are characterized by a broad shape, with a wide flood plane, a very gentle gradient and the water current is low.

Calculate the Density of the substances below to determine if they will float or sink in water.

Reil [10]

Explanation:

If the density of the object is more than that of water, it will sink. Otherwise it will float. The density of water is 1 g/mL.

Substance 1,

Mass, m = 450 g, Volume, V = 90 mL

Density = mass/volume

So,

$d_1=\dfrac{450}{90}\\\\=5\ g/mL$

It will sink.

Substance 2,

Mass, m = 35 g, Volume, V = 70 mL

Density = mass/volume

So,

$d_2=\dfrac{35}{70}\\\\=0.5\ g/mL$

It will float.

Substance 3,

Mass, m = 24 g, Volume, V = 12 mL

Density = mass/volume

So,

$d_3=\dfrac{24}{12}\\\\=2\ g/mL$

It will sink.
