Answer : S) 33.2 °C
Explanation : When the equal amounts of gases are placed in identical containers but subjected to different temperatures would exert pressure in different amount which will in turn increase the rate of collision between the molecules of gas.
So, when the temperature is increased to maximum greater amount of force would be exerted and the gas molecules will collide with a larger force. Hence the answer will be as the highest temperature i.e. 33.2 °C
Through the negative born?
Answer:
109.97JK-1
Explanation:
Entropy is the degree of disorderliness of a substance. It is given by ∆H/T where T is the absolute temperature in Kelvin.
Given ∆H= 38.6*10^3
T=78°C+ 273=351K
∆S=38.6*10^3/351=109.97JK-1 as shown the diagram.
Answer: The mass of oxygen per gram of nitrogen is 0.57
Explanation: Given Mass of Nitrogen (N2) = 30.82 g
Given Mass of Oxygen (O2) = 17.60 g
Thus the mass of oxygen per gram of nitrogen can be calculated by dividing the given mass of the oxygen by the given mass of the nitrogen.
Thus, Mass of oxygen per gram of nitrogen = 17.60 g / 30.82 g = 0.57
Thus the answer is 0.57
Answer:
61.4 %
Explanation:
Let's consider a generic chemical reaction.
Reactants ⇒ Products
The theoretical yield is the maximum mass of product that theoretically can be obtained from the chemical reaction.
The actual yield is the mass of the product obtained from the reaction.
The percent yield is:
Percent yield = actual yield / theoretical yield × 100%
Percent yield = 60.9 g / 99.2 g × 100% = 61.4 %
