Answer: The number of moles of nitrogen will be 3.57 moles.
Explanation:
To calculate the number of moles, we use the following equation:
We are given:
Given mass of the nitrogen = 100 g
Molar mass of the sample = 28g/mol
Putting values in above equation, we get:
Hence, the number of moles of nitrogen will be 3.57 moles.
Answer:
<h2>675 mmHg</h2>Explanation:
The new pressure can be found by using the formula for Boyle's law which is
Since we're finding the new pressure
We have
We have the final answer as
<h3>675 mmHg</h3>Hope this helps you
Answer:
The correct answer is option D.
Explanation:
Rate of the reaction is a change in the concentration of any one of the reactant or product per unit time.
Rate of the reaction:
Rate of decrease in nitrogen dioxide concentration is equal to the rate of decrease in carbon monoxide.
Given rate expression of the reaction:
Rate of the reaction on doubling concentration of nitrogen dioxide and carbon monoxide : R'
Doubling the concentrations of nitrogen dioxide and carbon monoxide simultaneously will increase the rate of the reaction by a factor of eight.
Hence, none of the given statements are true.
Answer:
<h2>18 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 62 - 52 = 10 mL
From the question we have
We have the final answer as
<h3>18 g/mL</h3>Hope this helps you
