Explanation:
The total mass will be as follows.
Total mass = mass of silver ring 
+ mass of gold ring 
And, heat lost by gold and silver rings = heat gained by water
![[M_{G} \times 0.128 J/g^{o}C \times (66.887 - 24.2)^{o}C] + [M_{s} \times 0.235 J/g^{o}C \times (66.887 - 24.2)^{o}C]](https://tex.z-dn.net/?f=%5BM_%7BG%7D%20%5Ctimes%200.128%20J%2Fg%5E%7Bo%7DC%20%5Ctimes%20%2866.887%20-%2024.2%29%5E%7Bo%7DC%5D%20%2B%20%5BM_%7Bs%7D%20%5Ctimes%200.235%20J%2Fg%5E%7Bo%7DC%20%5Ctimes%20%2866.887%20-%2024.2%29%5E%7Bo%7DC%5D)
= 
= 133.368
= 3.124
= 3.124
= 3.124
= 7.897 g
Thus, we can conclude that the mass of gold ring is 7.897 g.

Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The given equations are balanced as:

Answer:
to explore the Kupier Belt
Explanation:
just finished the test
V1/T1=V2/T2
V2=(V1)(T2)/T1
Plug in values given (for the temp you can either turn 300K to 27°C or turn 132°C into kelvin
V2= 4400 mL= 4.4L
