Answer:
43.93 g/mol
Explanation:
The mass of the gas before reaction = 52.1487 g
The mass of the gas after reaction = 52.1098 g
Mass of gas generated = 0.0389 g
Moles of the gas =
The formula for the calculation of moles is shown below:
Thus,
Molar mass of the gas = 43.93 g/mol
Answer:
The balanced reaction in the acidic medium is:
Explanation:
1) ( oxidation)
Balance oxygen by adding water :
Now , balance hydrogen by adding hydrogen ions on the side where hydrogen are less.
Add electrons to balance charge where positive charge is more.
..[1]
2) (reduction)
Balance oxygen by adding water :
Now , balance hydrogen by adding hydrogen ions by adding them on the side where hydrogen are less.
..[2]
Add electrons to balance charge where positive charge is more.
..[2]
3 × [1] + 2 × [2]
The balanced reaction in the acidic medium is:
Answer:
One of the main components of an airbag is the gas that fills it. As part of the design process, you need to determine the exact amount of nitrogen that should be produced. Calculate the number of moles of nitrogen required to fill the airbag. Show your work. Assume that the nitrogen produced by the chemical reaction is at a temperature of 495°C and that nitrogen gas behaves like an ideal gas. Use this fact sheet to review the ideal gas law.
About 75% of earth’s surface is covered by the ocean
Answer:
K₂Cr₂O₇(s) ⇒ 2 K⁺(aq) + Cr₂O₇²⁻(aq)
Explanation:
Potassium dichromate (K₂Cr₂O₇) is a strong electrolyte, that is, when dissolved in water (the medium), it dissociates in cation potassium (K⁺) and anion dichromate (Cr₂O₇²⁻). The balanced dissociation equation is:
K₂Cr₂O₇(s) ⇒ 2 K⁺(aq) + Cr₂O₇²⁻(aq)
