<h3>Answer </h3>

Potassium nitride= K3N

<h3>Explanation </h3>

Potassium nitride is the correct name of the compound with chemical formula, K3N. The compound is formed between potassium ion (K+) and nitride ion (N-3).

Potassium has nineteen electrons and since it obeys octet rule with electronic configuration of 1s2 2s2 2p6 3s2 3p6 4s1. Potassium loses an electron in its outer subshell(4s) to attain a stable electronic configuration (1s2 2s2 2p6 3s2 3p6). Thus, forming K+.

On the other hand, N has seven electrons with electronic configuration of 1s2 2s2 2p3. Nitrogen also obeys octet rule. Hence, it acquires three electrons to attain a stable octet noble gas configuration (1s2 2s2 2p6), resulting in N-3.

Every nitrogen atom acquires three electrons from potassium. Also, potassium loses one electron to each nitrogen atom. In this interaction every nitrogen atom becomes N-3 and each potassium becomes K+.

<span>You need to consider the valences of the two elements. Potassium is +1; nitrogen is -3. To balance the molecule, you need 3 potassium to one nitrogen, or K3N</span>

Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins. Note that
adelina 88 [10]

Answer:

The three-step synthesis of trans-2-pentene from acetylene is as follows.

<u>Step -1:</u> Formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkanes.

<u>Step -2:</u> Formation terminal alkyne to nonterminal alkynes.

<u>Step -3:</u> Formation of trans-pent - 2-pent-ene by reduction.

Explanation:

Synthesis of trans-pent-2-yne from ethyne takes place is mainly a three step synthesis which involves formation of higher order terminal alkyne on reaction with sodium acetylides with haloalkane. Second step involves the further alkylation of terminal alkynes to higher order nonterminal alkynes and the third step involves the formation of trans-2-ene by dissolving reduction method.

The chemical reaction of each step of chemical reactions is as follows.

Answer:

How does non-human life in an urban ecosystem differ from that in an undeveloped forest ecosystem?

Explanation:

In forest eco system the people are uncivilized and not so much educated. And in urban eco system people are intelligent as well as educated this is the main reason. In an urban ecosystem, the only non-human life that live there are the ones that are able to survive under the conditions. However, in undeveloped forest ecosystems, there’s barely any pollution. Therefore, a bigger variety of non-human life is able to live here.

Ralph and Sheila are at a construction site and they are stacking bricks. The diagram above shows the bricks before they touch.
aliya0001 [1]

Answer: Sheila's top brick will be cooler than Ralph’s top brick, because Sheila’s started with more total energy, so less energy had to transfer for both her bricks to reach the same total energy.

Butane gas (C4H10) burns in oxygen gas to produce carbon dioxide gas and water vapor. Balance the equation for this reaction (in
bixtya [17]

Answer:

C₄H₁₀(g) + O₂(g) ⇒ CO₂(g) + H₂O(g)

2 C₄H₁₀(g) + 13 O₂(g) ⇒ 8 CO₂(g) + 10 H₂O(g)

Explanation:

Butane gas (C₄H₁₀) burns in oxygen gas to produce carbon dioxide gas and water vapor. The unbalanced equation is:

C₄H₁₀(g) + O₂(g) ⇒ CO₂(g) + H₂O(g)

First, we will balance carbon and hydrogen which are in just one compound on each side.

C₄H₁₀(g) + O₂(g) ⇒ 4 CO₂(g) + 5 H₂O(g)

Finally, we will balance the oxygen atoms.

C₄H₁₀(g) + 6.5 O₂(g) ⇒ 4 CO₂(g) + 5 H₂O(g)

In order to have integers, we will multiply everý compound by 2.

2 C₄H₁₀(g) + 13 O₂(g) ⇒ 8 CO₂(g) + 10 H₂O(g)
