<u>Answer:</u> The pressure of carbon dioxide gas is 11 atm
<u>Explanation:</u>
To calculate the pressure of gas, we use the equation given by ideal gas equation:
PV = nRT
where,
P = pressure of the gas = ?
V = Volume of gas = 25 L
n = number of moles of gas = 10 mole
R = Gas constant =
T = temperature of the gas = 325 K
Putting values in above equation, we get:
Hence, the pressure of carbon dioxide gas is 11 atm

Density is sensitive to temperature for gases and liquids, although not much for liquids. We use the data in the picture. Using linear interpolation, we determine the densities at 14°C and 20°C.
@20°C: Density = 0.99823 g/cm³ or g/mL
@14°C:
(10 - 14)/(10 - 20) = (0.99973 - Density)/(0.99973 - 0.99823)
Solving for density:
Density = 0.99913 g/cm³ or g/mL
Mass @ 20°C = 50 mL * 0.99823 g/mL = 49.9115 g
Mass @ 14°C = 50 mL * 0.99913 g/mL = 49.9565 g
Difference of Masses = |49.9115 g - 49.9565 g| = 0.045 g
Answer:
B. KBr + F2
Explanation:
In displacement reactions (reactions in which an element replaces another element in a compound) like these, reactive element displaces the less reactive element.
A. NaBr + I2
This reaction will not occur because Iodine is not able to displace bromine from the compound.
B. KBr + F2
This reaction will occur because flourine is more reactive and hence is able to displace bromine from the reaction.
C. LiF + Cl2
This reaction will not occur because chlorine is not able to displace flourine from the compound.
D. NaCl + I2
This reaction will not occur because Iodine is not able to displace Chlorine from the compound.
