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.

Well first we can say that B. and D. are out BC they are physical changes we are looking for chemical changes when burning gas, the gas is burning and converting into heat energy AKA FIRE!!!. so the answer is indeed (A. <span>Chemical bonds are broken and others are formed.)

any ways i hope you can learn something new from this. :) <3 have any amazing day
Explanation:
No of mass = no of moles × molar mass
=2.55 × 18 g
= 45.9 g
Taking into account the definition of density, the density of the sample is 0.5
.
It is necessary yo know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density allows you to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

In this case, you know:
Then, replacing in the definition of density:

Solving:
<u><em>density= 0.5 </em></u>
<u><em /></u>
Finally, the density of the sample is 0.5
.
