Answer:
The value of partial pressure of oxygen
= 83.66 K pa
Explanation:
Volume of oxygen = 80 liters
Temperature = 50°c
The total pressure = 96 K pa
The partial pressure of water at 50°c is calculated from the tables.
= 12.344 K pa
The total pressure is given by

Put all the values in the above equation we get
96 = 12.344 + 
96 - 12.344
= 83.66 K pa
This is the value of partial pressure of oxygen.
The empirical formula is obtained by calculating the mole ratios of the atoms in the elements.
The number of moles =mass/ R.A.M
For hydrogen, no. of moles=8/1=8
For oxygen, no. Of moles=64/16=4
The tabular solution is attached.
Answer:
The exact result is 82.5 min (close to c. 80 min)
Explanation:
Hello,
In the following picture you'll find the numerical procedure for this exercise.
- Take into account that the initial concentration and the velocity constant remain constant for the two mentioned scenarios.
Best regards.
Work done by me for using force of 4 N to push an object 3 m away is 12 J.
<u>Explanation:</u>
Work done on any object is defined as the force required to displace that object from its original position. In other terms, the work done is the measure of force utilized for moving an object. So mathematically it is represented as the product of force with the displacement of the object due to that force.

Then, here it is given that force of about 4 N is used to displace the object to 3m. Thus,

So, 12 J of work is done by me to push an object 3 m away with the force of 4 N.
