Assuming that the required amount of chlorine is added, we may calculate the mass of chlorine present in the product by first calculating the amount of product that will be formed from 15 grams of phosphorus.
Phosphorus has an atomic mass of 31, so 15/31 moles of phosphorus are added.
Next, we see that due to the equimolar ratio, the moles of product formed are also 15/31
The molecular mass of phosphorus trichloride is 137 g/mol. Therefore, the mass of product is:
137 * 15/31
= 66.3 grams
Now we know that 15 grams of phosphorus are present, so the remaining amount must be chlorine.
Chlorine = 66.3 - 15
Chlorine = 51.3 grams
To determine the gas which has the higher initial temperature, we need an equation that would relate energy and temperature. From thermodynamics, we use the expression Energy = nCvT where n is the number of moles, Cv is the heat capacity at constant volume and T is the temperature. By evaluating the temperature of both gases we determine the which would have higher temperature.
4800 = 2.3CvT
T = 2086.96/Cv
8500 = 2.9CvT
T = 2931.03/Cv
Assuming that both gases are the same. Therefore, the value of Cv for both would be equal. So, we conclude that it is the second gas with 2.9 moles would have the higher initial temperature.
If an object is in rest it will stay at rest so it will stay put until a force acts upon it
Answer:
Explanation:
Given that
Volume
As we know that
So
So we cab say that is equal to .
Answer:
2kg
Explanation:
100N = Force 50m/s²= Acceleration
Mass=?
the equation is;
Mass(kg)= Force(N) ÷ Acceleration (m/s²)
100÷50=2
