Answer:
1
Explanation:
To adequately account for what happens to volume when pressure is increased, we need to know exactly the type of volume change that occurred. Now as we can see, there is a volume change from 2 moles to 7 moles.
This shows an increase in volume. To favor the forward reaction, there should be a decrease in the volume which is unfortunately not the case here. Hence it’s the backward reaction that would be favored.
Since the formation of NO2 is in the forward reaction, then, we can see that its concentration will decrease
Answer:
A difference of 1 would mean there is either x10 more or less depending on where you are starting.
Explanation:
The pH of 3 differs from 4 because the acidity of 3 is 10x higher than that of 4. This is due to how the scientific notation of 3 in relation to pH is 10x^-3 while that of 4 is 10^-4 so in terms of the stronger acid that would be the one with the pH of 3.
The heat of vaporization is when it changes phases from liquid to gas. When it is quite low, it means that it has weak attraction between the liquid particles
From the periodic table:
molar mass of silicon = 28 grams
molar mass of nitrogen = 14 grams
From the balanced chemical equation,
3 x 28 = 84 grams of silicon react with 2 x 2 x 14 = 56 grams of nitrogen to produce 3(28) + 4(14) = 140 grams of silicon nitride.
Since it is mentioned that nitrogen is the limiting reagent, therefore, the reaction will stop once the amount of reacting nitrogen is consumed.
Now we know that 56 grams of nitrogen produce 140 grams of silicon nitride. Thus, we can use cross multiplication to calculate the amount of silicon nitride produced when using 14.33 grams of nitrogen as follows:
amount of produced silicon nitride = (14.33 x 140) / 56 = 35.8 grams
