Answer:
C.
Explanation:
Noble gases are stable and already have a full outter shell therefore don't tend to lose or gain any electrons.
If it is just ratio you must just put the mass number on the either side of the symbol ‘:’ and cancel but the same process is not used to find simplest ratio
Answer:- The gas needs to be transferred to a container with a volume of 11.2 L.
Solution:- From Boyle's law. "At constant temperature, Volume is inversely proportional to the pressure."
It means, the volume is decreased if the pressure is increased and vice versa.
Here, the Pressure is decreasing from 537 torr to 255 torr. So, the volume must increase and calculated by using the equation:

Where,
is initial pressure and
is final pressure. Similarly,
is initial volume and
is final volume.
Let's plug in the values in the equation:
(537 torr)(5.30 L) = (255 torr)(
)

= 11.2 L
So, the new volume of the container needs to be 11.2 L.
Answer:
The coffee has a higher temperature because a pool is so you can have fun and relax in while coffee can warm you up by drinking it.

Hope it helps :)
The reaction is:
Cl2 + 2 KBr --> 2 KCl + Br2
Moles of KCl is
n = m /M = 12 /74 = 0.16 mol
As, twice the moles of KCl is producing from 1 mol of chlorine
mole of Cl2 = 0.16 /2 = 0.08 mol
Mass of Cl2
m /70 = 0.08 = 5.6 g
Hence, 5.6 g mol Cl2 consumed to produce KCl
