Answer: 0.082 atm L k^-1 mole^-1
Explanation:
Given that:
Volume of gas (V) = 62.0 L
Temperature of gas (T) = 100°C
Convert 100°C to Kelvin by adding 273
(100°C + 273 = 373K)
Pressure of gas (P) = 250 kPa
[Convert pressure in kilopascal to atmospheres
101.325 kPa = 1 atm
250 kPa = 250/101.325 = 2.467 atm]
Number of moles (n) = 5.00 moles
Gas constant (R) = ?
To get the gas constant, apply the formula for ideal gas equation
pV = nRT
2.467 atm x 62.0L = 5.00 moles x R x 373K
152.954 atm•L = 1865 K•mole x R
To get the value of R, divide both sides by 1865 K•mole
152.954 atm•L / 1865 K•mole = 1865 K•mole•R / 1865 K•mole
0.082 atm•L•K^-1•mole^-1 = R
Thus, the value of gas constant is 0.082 atm L k^-1 mole^-1
The answer is:
A. The reaction between A and B is reactant favored
Explanation:
Because the reaction favors reactants, their concentration will be higher at equilibrium than the products.
Answer:
precipitation and evaporation
Explanation:
salinity :salt concentration
Precipitation: this brings freshwater into the ocean which are not salty, so it is diluting its salt concentration.
evaporation: takes all the water and leaves the salt behind
Answer: The given decay sequence is 
.
Explanation:
An alpha-particle is a helium atom. Hence, when an alpha decay occurs in 
then the reaction equation is as follows.
Now, in sequence the equation for beta decay is as follows.
Hence, the sequence will be as follows.
Thus, we can conclude that the given decay sequence is .
