Answer:
The answer to your question is 1.51 moles of PBr₃
Explanation:
Data
moles of Br = 2.27
moles of PBr₃ = x
Balanced chemical reaction
2P + 3Br₂ ⇒ 2PBr₃
Reactant Element Products
2 P 2
6 Br 6
-Use proportions to find the answer
3 moles of Br₂ ------------------ 2 moles of PBr₃
2.27 moles of Br₂ ------------------ x
x = (2.27 x 2) / 3
x = 4.54 / 3
x = 1.51 moles
Answer:
H₂CO₃ (aq) ⇒ H₂O (l) + CO₂ (g)
Explanation:
Carbonic acid dissociates into water and carbon dioxide which is gas which is used as a fire extinguisher and also which is identified after expose to the flaming and glowing splints. It is a colorless gas which can be identified by brisk effervescence seen in the tube.
<u>The balanced reaction of the decomposition of carbonic acid is:</u>
<u>H₂CO₃ (aq) ⇒ H₂O (l) + CO₂ (g)</u>
Answer:
check the attached image. hope it helps
Explanation:
a. What does mol/L mean? mol/L means Molar Concentration
b. Describe in your own words how mol/L compares to grams/liter. (similarities and differences)
<u>Similarities:</u><u> </u>mol/L and grams/liter both are units of concentration.
<u>Differences</u>:
mol/L concentration says how many moles of solute are present in 1L of solution.
grams/liter concentration says how many grams of solute are present in 1L of solution.
3. Describe at least 2 ways in the simulation to change each of the parameters:
a. Volume of solution= evaporating or adding more water
b. amount of solute=reducing the water or evaporating more water
c. Concentration of solute in solution = evaporating or adding more solute
Answer:
Explanation: Water and Benzene are insoluble in each other. The molecules in a drop of benzene are not diluted by water molecules from nearby water droplets due to steam distillation so each liquid would exert its own vapor pressure. two liquids exert pressure against external pressures independently
