What is the concentration of the hydroxide ion? Given that the concentration of the hydronium ion is 2.3 X 10^-7 M

Chemistry

Answer:

4.35 * 10^-8 M

Explanation:

Since the concentration of the hydronium ion= 2.3 X 10^-7 M

And we know that;

[H3O^+] [OH^-] = 1 * 10^-14

[H3O^+]  = concentration of the hydronium ion

[OH^-] = concentration of the hydroxide ion

So;

[OH^-] =1 * 10^-14/[ H3O^+]

But [H3O^+] = 2.3 X 10^-7 M

[OH^-] = 1 * 10^-14/2.3 X 10^-7

[OH^-] = 4.35 * 10^-8 M

A Herbig-Haro (HH) object is:_:_________.
Phoenix [80]

Given what we know about Herbig-Haro (HH) objects, we can confirm that they are born from the collision between a jet from a star and clouds of interstellar matter.

<h3>What are Herbig-Haro (HH) objects?</h3>
  • To put it simply, a Herbig-Haro (HH) object is what we observe as a bright spot in distant space. Upon closer observation we can observe that these giant bright patches are not lone objects, but in fact immense groups of interstellar matter.

<h3>How Herbig-Haro (HH) objects are formed.</h3>
  • The formation of one of these interstellar groups requires an <em><u>immense amount of energy</u></em>. This energy come from the speed at which the materials that form these objects collide.
  • As stated in the question, the jet released from a star in the process of being born <em><u>smashes into a giant cloud of </u></em><em><u>dust </u></em><em><u>and </u></em><em><u>interstellar material </u></em><em><u>to form the </u></em><em><u>Herbig</u></em><em><u>-</u></em><em><u>Haro </u></em><em><u>(HH) </u></em><em><u>objects</u></em>.
  • This collision happens at hundreds of km/s. To put it into perspective, it would be roughly 500,000 miles per hour.

Therefore, we can confirm that option b, which states, "<em>where a jet from a </em><em>star </em><em>in the process of being born </em><em>collides </em><em>with (and lights up) a nearby cloud of </em><em>interstellar matter</em>", is the correct choice for the question pertaining to Herbig-Haro (HH) objects.

Draw the structure of two alkenes that would yield 1-methylcyclohexanol when treated with Hg(OAc)2 in water, then NaBH4:Draw the
disa [49]

Answer:

Two possible compounds are shown below- one with an exocyclic double bond and another one with an endocyclic double bond

Explanation:

Reaction of alkene with Hg(OAc)_{2} gives a complex of mercurous ion.

Then water molecule attacks this complex through S_{N}2 type reaction at more substituted position.

NaBH_{4} cleaves the resultant C-Hg bond and forms a C-H bond.

Two possible structures of an alkene is possible to yield 1-methylcyclohexanol which are shown below.
