Answer:
The rate of reaction of magnesium with hydrochloric acid. Magnesium reacts with dilute hydrochloric acid in a conical flask which is connected to an inverted measuring cylinder in a trough of water. The volume of hydrogen gas produced is measured over a few minutes, and the results are used to plot a graph.
Explanation:
Answer:
≈ 1.142 moles
Explanation:
formula is “grams given/molar mass = moles”
nitrogen’s molar mass is 14.0067g
solve:
16 / 14.0067 = 1.14231046571
or ≈ 1.142 moles
hope this helped :)
Answer:
Molarity = moles ÷ liters
to get moles of NaBr divide grams of NaBr by its molar mass (mass of Na + mass of Bromine)
Na = 22.989769
Br = 79.904
molar mass of NaBr = 102.893769
6.6g ÷ 102.893769 = 0.064143826 moles of NaBr
0.064143826 moles ÷ 0.60 liters = 0.1069 molar concentration or 11 %
D increase in temperature and increase in pressure.
