NaCI is the answer, in what my teacher taught me.
Hope I helped :)
Answer:
The correct answer to you your question is Potassium
Explanation:
Potassium is the most reactive
Pressure can affect the boiling pressure of a substance
as when pressure increases the particles are closer together and so require more energy to boil therefore increasing the substances boiling point
hope that helps
Answer:
- 13.56 g of sodium chloride are theoretically yielded.
- Limiting reactant is copper (II) chloride and excess reactant is sodium nitrate.
- 0.50 g of sodium nitrate remain when the reaction stops.
- 92.9 % is the percent yield.
Explanation:
Hello!
In this case, according to the question, it is possible to set up the following chemical reaction:

Thus, we can first identify the limiting reactant by computing the yielded mass of sodium chloride, NaCl, by each reactant via stoichiometry:

Thus, we infer that copper (II) chloride is the limiting reactant as it yields the fewest grams of sodium chloride product. Moreover the formed grams of this product are 13.56 g. Then, we take 13.56 g of sodium chloride to compute the consumed mass sodium nitrate as it is in excess:

Therefore, the leftover of sodium nitrate is:

Finally, the percent yield is computed via:

In order to calculate average speed we will calculate the total distance in meters traveled by cindy.
Distance = 2 Km
1 km = 1000m
So distance in meters = 2000 m
Then let us calculate the total time taken by cindy to cover these 2000 meters
Total time in minutes = 2 + 4 + 1 + 3 = 10 minute
Average speed = total distance / total time
Average speed = 2000 m / 10 minutes
average speed = 200 m / min
