Subatomic particles:
These are too small for people to really know much about them, scientists think that there are only about three: protons, neutrons, and electrons
They are called "energy levels".
Answer:
You’re taking a walk on a warm fall morning. The temperature is about 70 degrees Fahrenheit, and you cannot see a cloud anywhere in the sky. You notice that the ground has no dew on it either. This means the <u>relative humidity</u> is low.
When PH = -㏒[H3O+]
and we have PH = 5.061
by substitution:
∴ [ H3O+] = 10^-5.061 = 8.7x10^-6
when we have Ka = [CH3COO-][H3O+] / [CH3COOH]
we have Ka = 1.8x10^-5 & [H3O+] = 8.7x10^-6m & [CH3COOH] = 0.5 m
by substitution in Ka formula:
1.8x10^-5 = [CH3COO-]*(8.7x10^-6) / 0.5
∴[CH3COO-] = 1.034
∴we need to add 1.034 mol of sodium acetate
Phosphorus + Sulfur ------> Phosphorus sulfide
2P + 3S ------> P2S3
