Answer: (B) Pressure is due to the collisions of the gas particles with the walls of the container.
Option B helps to explain the factor behind gas collision under high pressure.
Explanation: Kinetic molecular theory explains the behaviour and movement of gas particles when they are in motion. It states that gas particles are always in continuous motion and are perfectly elastic in nature.
Kinetic molecular theory can be explained using both Boyle's law and Charles's law.
•Few Assumptions of Kinetic Molecular Theory.
1. Gas particles are always in motion and they collide with the walls of their container.
2. The space occupied by a gas particles is negligible in comparison to the volume of the gas
Answer:
C - Magnesium Chloride
Explanation:
The metal in a compounds name is always pronounced, and if the last element is a non-metal, the first half of the element is used and the last part is replaced with "ide"
Answer:
7.98 × 10^3grams.
Explanation:
To find the mass of fluorine in the number of atoms provided, we first divide the number of atoms by Avagadros number (6.02 × 10^23atoms) to get the number of moles in the fluorine atom. That is;
number of moles (n) = number of atoms (nA) ÷ 6.02 × 10^23 atoms
n = 2.542 × 10^26 ÷ 6.02 × 10^23
n = 0.42 × 10^ (26-23)
n = 0.42 × 10^3
n = 4.2 × 10^2moles
Using mole = mass ÷ molar mass
Molar/atomic mass of fluorine (F) = 19g/mol
mass = molar mass × mole
Mass (g) = 19 × 4.2 × 10^2
Mass = 79.8 × 10^2
Mass = 7.98 × 10^3grams.
The ground could sink and sink holes could occur, otherwise the parking lot could simply break apart and wear faster
