Answer:
Explanation:
2 NH₄ClO₄ ⇒ N₂ + Cl₂ + 2O₂ + 4 H₂O
2 moles 1 mole
We are required to produce 1.4 moles of N₂ from ammonium perchlorate .
1 mole of N₂ is produced by 2 moles of ammonium perchlorate
1.4 moles of N₂ will be produced by 2 x 1.4 = 2.8 moles of ammonium perchlorate .
Answer is 2.8 moles .
Answer:
Neither
Explanation:
Kinetic, or potential energy, is the average amount of molecules in a substance
The precaution to be taken while measuring the temperature of a liquid in a beaker is applying proper heat balance and taking all the required precautions.
- A beaker with an open top contains a sample of liquid. It exposes this sample to light.
- That liquid absorbs the light energy, turning it into heat energy. As a result, the liquid becomes warmer and evaporation is accelerated. As a result, there is less liquid in the beaker.
- Since it is well known that the surface temperature of a liquid, along with air movement above the liquid surface, is one of the dominant factors affecting evaporation, I want to measure the evaporation rate as a function of surface temperature.
- This can be done by applying a heat balance.
