Answer:
100°C
Explanation:
The following were obtained from the question:
Initial temperature (T1) = 298 K
Initial pressure (P1) = 32.5 Psi
Final pressure (P2) = 40.68 Psi
Final temperature (T2) =..?
The final temperature can be obtained as follow:
P1/T1 = P2/T2
32.5/298 = 40.68/T2
Cross multiply to express in linear form
32.5 x T2 = 298 x 40.68
Divide both side by 32.5
T2 = (298 x 40.68) /32.5
T2 = 373K
Next, we shall convert 373K to celsius.
This is illustrated below:
T(°C) = T(K) – 273
T(K) = 373
T(°C) = 373 – 273
T(°C) = 100°C
Therefore, the temperature of the air inside the tire at 40.68 Psi is 100°C
Answer:
The food chain starts as prey to a preditor and then when the preditor dies the prey eat the preditor
Explanation:
Just that
The answer is A because it cant pollute the atmosphere because its vapor from water that is being thrown out and it is reusable / the chemical reaction last longer
Answer : The mixture of acetone and alpha naphthol can be separated using simple distillation method.
Explanation :
The melting point of alpha naphthol is around 95 °C whereas boiling point of acetone is around 55°C. Therefore the mixture can be separated using simple distillation method.
In this method, the mixture is taken in a stoppered bottle which has a tube inserted through the stopper for passing the vapors .The container is gently heated. Acetone being volatile, gets converted to vapors at its boiling point. Since melting point of alpha naphthol is much higher than the boiling point of acetone, it remains in dissolved form and does not melt when the mixture is heated.
The vapors of acetone are passed through the tube and as they pass through the tube, they get condensed. The condensed liquid is collected in another container.
After all the acetone is evaporated, solid alpha naphthol is left at the bottom of the container.
In this manner, the mixture of acetone and alpha naphthol is separated.
The breakdown of NO3 in the day leads to more consumption of N2O5 in the day hence its concentration is greater at night than in the day.
<h3>What is equilibrium constant?</h3>
The equilibrium constant is a number that shows how much reactants are converted to products in a reaction. It is often shown as capital letter K in English.
Given the situation described in the question, we know that the concentration of N205 will be higher at night, because the decomposition of NO3(g) in the daytime will result in an increase in the rate of consumption of N2O5(g) to reform NO3(g).
