Answer:
Explanation:For example, you are in a bus and it goes with the velocity of 50 m/s to the east, then a truck passes you with a velocity of 60m/s to the east. ... Velocity of the moving objects with respect to other moving or stationary object is called “relative velocity” and this motion is called “relative motion”
The final temperature of the mass of gold is 737 °C.
<h3>What is the specific heat capacity of gold?</h3>
The specific heat capacity of gold is 0.126 J/g/K
The final temperature, T2 of the gold is calculated as follows:
T2 = T + Q/mc
where;
T is initial temperature, m is mass, and c is specific heat capacity of gold.
T2 = 27 + 2.3 x 1000/(25 x 0.126)
T2 = 737 °C
Therefore, the mass and heat capacity of gold determines its final temperature.

Answer:
The correct approach is "-2.67 kJ/mole". A further solution is described below.
Explanation:
The given values are:
No. of moles,
= 5.60 mol
Substance releases,
ΔH = 14.9 kJ
Now,
The ΔH in terms of kJ/mol will be:
= 
On putting the given values of ΔH, we get
= 
=
