Answer:

[Y₂] = 31.25M

Explanation:

Based on the chemical reaction:

2X(g) + Y2(g) ⇌ 2XY(s)

We must define the equilibrium constant, K as:

K = 20 = 1 / [X]²[Y₂]

<em>Where</em> [X] and [Y₂]<em> are the equilibrium concentrations of each gas.</em>

<em />

If [X] = 4.0x10⁻²M:

20 = 1 / [4.0x10⁻²M]²[Y₂]

0.032 = 1 / [Y₂]

<h3>[Y₂] = 31.25M</h3>

Ne4ueva [31]

Answer:

a. True

Explanation:

Alkanes are chains of carbon atoms surrounded by hydrogen atoms. TRUE.

Alkanes are hydrocarbons, that is, they are organic compounds formed only by carbon and hydrogen. In alkanes, carbon atoms are bonded to each other through single covalent bonds and they are also bonded to hydrogen atoms through the same type of bonds. Alkanes have the general formula CnH2n+2.
