Answer:
Whenever you are doing calculations with gases and temperature, you must convert the temperature from C into Kelvin. Then, just plug in your values and do the calculation. So, for the first one,
32C + 273 = 305 K
63C + 273 = 336 K
Then, P1/T1 = P2/T2
575 torr / 305 K = P2 / 336 K
P2 = 633 torr
For the second one:
P1/T1 = P2/T2
575/305 = 5750 / T2
T2 = 3050 K
Answer:
flourine 19F-
Explanation:
because we have 1 extra electron so the charge should be negative, then check the number of protons to know the atomic number, and 9 is flourine
Answer:
The specific heat of the alloy
Explanation:
Mass of an alloy = 25 gm
Initial temperature = 100°c = 373 K
Mass of water = 90 gm
Initial temperature of water = 25.32 °c = 298.32 K
Final temperature = 27.18 °c = 300.18 K
From energy balance equation
Heat lost by alloy = Heat gain by water
[ - ] = ( - )
25 × × ( 373 - 300.18 ) = 90 × 4.2 (300.18 - 298.32)
This is the specific heat of the alloy.
