Answer:

C. Galactic disk

Explanation:

The galactic disk is a component of the spiral galaxies and consists of stellar and gaseous components as it forms a random motion with the circular objects that orbit around the galactic center.

The rotational curve in a milky way is similar to that of the rotation of the universal rotating disk and is evident by the dark matter in the galaxies.

What is the best name for the molecule below?

Sati [7]

You start numbering from the side with the methyl group and find the longest chain, which is seven = hept. The triple bond is -yne at C3. The methyl group is on C2.
This means that the best name for this molecule is 2-methyl-3-heptyne.

Consider the following chemical reaction: CO (g) + 2H2(g) ↔ CH3OH(g) At equilibrium in a particular experiment, the concentratio

boyakko [2]

Answer:

The concentration of CH₃OH in equilibrium is [CH₃OH] = 2,8x10⁻¹ M

Explanation:

For the equilibrium:

CO (g) + 2H₂(g) ⇄ CH₃OH(g) keq= 14,5

Thus:

14,5 = $\frac{[CH_{3}OH]}{[CO][H_{2}]^2}$

In equilibrium, as [CO] is 0,15M and [H₂] is 0,36M:

14,5 = $\frac{[CH_{3}OH]}{[0,15][0,36]^2}$

Solving, the concentration of CH₃OH in equilibrium is:

[CH₃OH] = 0,28M ≡ 2,8x10⁻¹ M

I hope it helps!
