Answer:
Volume of the gas at 500 mm Hg pressure is 960
Explanation:
Let's assume the gas behaves ideally.
According to combined gas law for an ideal gas-
Where and
are initial and final pressure of the gas respectively.
and
are initial and final volume of the gas respectively.
and
are initial and final temperature of the gas in kelvin respectively.
Here =
,
= 1200
,
= 400 mm Hg,
= 500 mm Hg
So,
Hence =960
[/tex]
Hence volume of the gas at 500 mm Hg pressure is 960
Answer:
Explanation:
Hello,
At first, we must consider that at the beginning, both copper and silver are solid, so we must melt both of them, thus, the following enthalpic routes are proposed in order to know each heat because coppers melting points as a value of 1356K and silver's melting point 1235K:
Now, the released heat due to the mixing process turns out into:
Finally, the total heat required is found by:
