Answer: 0.0624 atm
Explanation:-
According to the ideal gas equation:
P = Pressure of the gas = ?
V= Volume of the gas = 45.0 L
T= Temperature of the gas = -10.0°C = 263 K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas
Moles of gas=
The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm
I don't know how 5°C cooled to 85°C but the answer would be 12.878L
Explanation:
Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.
= k
where, k = rate constant
n = order of reaction
For the given reaction,
Hence, its rate will be as follows.
Rate =
Also, it is known that slowest step in a chemical reaction is the rate determining step.
Hence, for the given rate law correct reaction is as follows.
Step 1 : (slow)
Balancing this equation it becomes (slow)
Step 2: (fast)
Answer:
Polar Covalent
Explanation:
Chlorine and Fluorine are both halogens. They are in group VII.
The Pauling's electronegativity value of these elements are:
F = 4.0
Cl = 3.0
Electronegativity of an element is a property that combines the ability of its atom to lose and gain electrons. It can be used to predict bond type.
For heteronuclear molecules where the electronegativity difference is between 0.5 and 1.7 there will not be an equal sharing of the electron pair between the atoms involved.
The bond that results is a Polar Covalent bond.
When the electronegativity difference is zero or less than 0.5, a non-polar covalent bond forms. There would be an equal sharing of the electron pair donated.
