Answer:
Explanation:
Hello!
In this case, since the formation of ammonia by starting with nitrogen and therefore hydrogen is:
Which has an energy of reaction of:
We can compute the energy required for this reaction by first computing the moles of ammonia yielded by 21.7 grams of nitrogen (28.02 g/mol) via stoichiometry:
Thus, the energy turns out:
Best regards!
Molarity is the molar concentration of the chemical species of the solute dissolved in the solvent. The molarity of the solution when diluted is 0.0257 M.
<h3>What is the relation between molarity and dilution?</h3>
The molar concentration or the molarity of the solution is inversely proportional to the dilution. An increased dilution will decrease the molarity of the solution.
The molarity is given by:
Also, it can be shown as:
Given,
= 0.513 M
= 25 mL
= ?
= 500 mL
Substitute value in the equation as:
Therefore, 0.0257 M is the molarity after dilution.

Answer:
C: remaining at rest
Explanation:
Acceleration (a) is the change in velocity (Δv), remaining at rest is not changing the velocity.
