The ways in which ammonia can be identified is mentioned in below pointers.

<h3>What is Ammonia ?</h3>

Ammonia is a compound of nitrogen and hydrogen with the formula NH3.

A stable binary hydride, and the simplest pnictogen hydride.

Ammonia is a colourless gas with a distinct pungent smell.

Biologically, it is a common nitrogenous waste,

Three ways in which ammonia gas can be identified is:

It has a sharp characteristic odor.

When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed.

It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.

Answer:

Texture Gradient

Explanation:

Texture Gradient -

It refers to the disrupted pattern on any uniform surface , is referred to as the texture gradient .

The pattern is somewhat very uniform in nature , i.e. , is constant over a particular area .

The three types of texture gradient are-

perspective ,
density and
distortion of texture elements .

Hence , from the given information of the question ,

The correct answer is texture gradient .

Alona [7]

Answer:

I'm taking a guess here. Aluminum.

Explanation:

The best conductor of heat would be the material that melted the ice fast. A.K.A. the one with the least amount of minutes. Since aluminum has the least, it is the best conductor of heat

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. One of

pochemuha

Answer:

1,4-dihydro = 113 kJ·mol⁻¹

1,2-dihydro = 101 kJ·mol⁻¹

Explanation:

In 1,4-dihydronaphthalene, the 2,3-double bond is isolated from the benzene ring.

In 1,2-dihydronaphthalene, the 3,4-double bond is conjugated with the benzene ring.

Thus, 1,2-dihydronaphthalene is partially stabilized by resonance interactions between the ring and the double bond (think, styrene).

1,2-Dihydronaphthalene is at a lower energy level because of this stabilization.

The heat of hydrogenation of 1,2-dihydronaphthalene is therefore less than that of the 1,4-isomer when each is hydrogenated to the common product, 1,2,3,4-tetrahydronaphthalene.

Assuming an electron is a hydrogen atom can undergo any of the transitions below, thus changing its energy. Which transition is

inn [45]

Answer:

n = 3 to n = 5

Explanation:

According to the Bohr's model of the atom, electrons in an atom absorb energy to move from a lower to higher energy level.

We must note that as we progress away from the nucleus, the energy levels of electrons become closer together. The energy difference between successive levels decreases and the wavelength of light associated with such transitions become longer.

Hence,the absorption of light of the longest wavelength corresponds to n = 3 to n = 5
