The electron is a subatomic particle that has a negative charge and a negligible mass. The electron travels around out side the nucleus.
The subatomic particles that are inside the nucleus are protons and neutrons.
The answer to your question is electron.
The answer is london dispersion forces. It is one of two intermolecular forces that is present in all molecules!
W = force x distance
50 N x 20 m = 1,000 joules
For the first answer.
Answer:
9.46 M
Explanation:
Molarity is a measure of the molar concentration of a solution. It can be calculated by the following formula
Molarity = number of moles/volume
Using moles = mass/molar mass
Molar Mass of Ammonium sulfate (NH₄)₂SO₄ =
{14 + 1(4)}2 + 32 + 16(4)
= {14 + 4}2 + 32 + 64
= 18(2) + 96
= 36 + 96
= 132g/mol
mole = mass/molar mass
mole = 62.42 ÷ 132
mole = 0.473mol
- Molarity = mole ÷ volume
Volume = 50.0 mL = 50/1000 = 0.05 L
Molarity = 0.473 ÷ 0.05
Molarity = 9.46 M
