Answer:
erosion
Explanation:
erosion is the term that refers to the process by which land is worn away by natural forces or human activity.
Answer:
An -ite or -ate ending means a polyatomic ion that includes oxygen is in the formula.
ate = one more O than -ite
Explanation:
Example:
NO2 is nitrite
NO3 is nitrate
You can see that the molecules are made of the same elements, however they have more or less of one of the elements (i.e. oxygen).
A person would weigh more on Neptune than on planet earth because the gravitational field strength is stronger on Neptune.
Answer:
Iron, as well as iron alloys, rusts because of a chemical reaction known as oxidation. When iron is exposed to moisture or oxygen, oxidation occurs. During this chemical reaction, iron is converted into iron oxide
The osmotic pressure is a colligative property which depends upon the number of molecules and not the type of molecules
The relation between osmotic pressure and concentration is
πV = nRT
where
π = Osmotic pressure [ unit atm] = ?
V = volume
n = moles
R = gas constant = 0.0821 L atm / mol K
T = temperature = 20°C = 20 + 273.15 K = 293.15 K
also
Molarity = moles / Volume
So
Molarity = n/V = 5.5 M
Putting values
π = MRT
π = 5.5 X 0.0821 X 293.15 = 132.37 atm
Osmotic pressure of given glucose solution will be 132.37 atm
