Does xenon react with nitrogen and explain why

KiRa [710]

No, xenon will not react on Nitrogen because xenon only reacts with oxygen and fluorine. Xenon only reacts with the 2 elements because these 2 elements contain a strong electronegative element which is high in energy barrier that can move the electrons inside xenon elements. Xenon is an element with a symbol of Xe, it is odorless and colorless gas. Common uses of xenon are flash lamps and arc lamps. Xenon is a luminous element, it glows when placed near to high voltage electric field.

Answer:

6.286 L.

Explanation:

Applying Charles Law,

V/T = V'/T'............................... Equation 1

Where V = Initial volume of the balloon, T = Initial Temperature of the balloon, V' = Final volume of the balloon, T' = Final Temperature of the balloon

make V' the subject of the equation

V' = VT'/T............................ Equation 2

Given: V = 6.50 L, T = 31 °C = (273+31) K = 304 K, T' = 21 °C = (273+21) K = 294 K

Substitute into equation 2

V' = 6.5(294)/304

V' = 6.286 L.

Hence the new volume in the balloon = 6.286 L.

Identify the chirality center (sometimes called chiral atom) or centers in each compound. if the molecule does not contain a chi

Dmitrij [34]

Chiral Carbons are those carbons which are attached to four different atoms or groups. Below are the four structure, Among these structures,

Structure C has no chiral carbon because the carbon to which methyl group and hydrogen atom attached is further attached to groups of same environment.

Structure A has one chiral center (highlighted RED).

Structure B has three chiral centers.

Structure D has two chiral centers.

Below are the structures,
