Elements don't take part in covalent bonding are called lone pair. Ammonia, and Water are the examples
Answer:
No, he is not.
Explanation:
When he let the rubber band go, the band compresses, so there's elastic potential energy in it, which will be transformed into kinetic energy when it gains velocity and flies across the room.
Then, Elias had inverted the concepts: the experiment demonstrates the transformation of elastic potential energy to kinetic energy.
Answer:
Mole = 2.67
Given data:
Number of atoms of carbon = 1.61 × 10²⁴
Avogadro's Number = 6.023 × 10²³
Required:
Moles = ?
Solution:
Formula for calculating moles from particle numbers is given as,
Mole = Number of particle / Avogadro's number
putting values
Moles = 1.61 × 10²⁴ / 6.023 × 10²³
Moles = 2.67
Answer: The pressure will be 411 GH.
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume
Mathematically,
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the pressure will be 411 GH.
