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!
Answer:
qualitive
Explanation:
Qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing.
Answer:
3.451 mL.
Explanation:
- It is a dilution process.
- We have the rule states that the no. of millimoles before dilution is equal to the no. of millimoles after dilution.
<em>(MV) before dilution = (MV) after dilution</em>
M before dilution = 5.0 M.
V before dilution = ??? mL.
M after dilution = 0.17 M.
V after dilution = 101.5 mL.
∴ The volume before dilution = (MV) after dilution / M before dilution = (0.17 M)(101.5 mL) / (5.0 M) = 3.451 mL.
