Answer:
new Volume of gas=360L
Explanation:
Assume that given gas follow the ideality nature of gas
Assuming that temperature is constant;
P1 and V1 are the initial parameter of gas
and p2 and V2 are the parameter after increasing the pressure
according to boyle 's law pressure is inversly proportional to the volume at constant temperature.
given value of volume and gas
P1=90kPa
V1=600L
P2=150kPa
V2=?
After putting all values we get;
V2=360L
new Volume of gas=360L
Answer:
Transition from n = 4 to n = 1 corresponds to shortest wavelength.
Explanation:
Process 
A 0.9375
B 0.75
C 0.0421
D 0.1875
According to Rydberg equation for electronic transition in H-like atoms:
where, 
is wavelength of light emitted or absorbed, 
is Rydberg constant.
So, higher the value of 
, lower will the corresponding wavelength of light.
Hence process A will be associated with shortest wavelength.
Answer:
C. The reaction rate at known reaction concentrations
Explanation:
The rate of a reaction is the measure of the speed of a chemical reaction. To find the rate constant of a reaction, the concentration of the reactants must be known.
- Reaction rate is directly proportional to the concentration of the reactants.
- The quantitative relationship between the rate of a reaction and the concentrations of reactants is expressed as the rate law.
- From this we can deduce the rate constant.
Answer:A
Explanation:
They are proposed at the beginning of the scientific process to serve as a guide before carrying out scientific research and experimentation
