Star B is closer than star A, because 1/ 0.58 = 1.72 pc, while 1/.73 = 1.36 pc.
<h3>What is stellar parallax and distance measurement using stellar parallax?</h3>To calculate the distances to nearby stars, astronomers employ a phenomenon known as parallax. The apparent displacement of an object due to a change in the viewer's point of view is known as parallax. The distances between close stars can be calculated using this phenomenon. A nearer star will seem to move against the farther-off background stars as the Earth revolves around the Sun. By measuring a star's position once, then again six months later, astronomers can establish the apparent shift in location of that star. The apparent motion of the star is referred to as stellar parallax.
A straightforward correlation exists between the distance of a star and parallax angle:
The distance d and parallax angle p are both measured in parsecs and arcseconds, respectively.
Stellar parallax of star A= 0.58 arcseconds
Stellar parallax of star B= 0.73 arcseconds
So, on applying the formula,
The distance of the star A= 1.72pc
And the distance of the star B= 1.36pc
Therefore, star B is closer than star A.

Answer : The value of is 4.76 J
Explanation :
Formula used :
According to the ideal gas equation,
So,
where,
= internal energy of the reaction = -358 J
= enthalpy of the reaction = ?
= initial pressure = 0.36 atm
= final pressure = 0.34 atm
= initial volume = 8 L
= final volume = 19 L
Now put all the given values in the above formula, we get:
conversion used :
Therefore, the value of is 4.76 J
