The key difference between volumetric analysis and titration is that the term volumetric analysis is used where analysis is done to analyse a solution for several different unknown values whereas the term titration is used where the concentration of an unknown component of a solution is determined
Answer:
The molar mass of water is 18 grams per mole. So in 18 grams of water, there are 6.02 x 1023 molecules.
One gallon of water is equal to 3.7854118 liters. If we assume that the water is at 4 °C (to keep things simple), the density of water is exactly 1 gram per milliliter, or 1 kilogram per liter. So 1 gallon of water at 4 °C weighs exactly 3.7854118 kilograms, or 3785.41118 grams.
If one mole of water weighs 18 grams, then there are 210.30 moles of water in a gallon. Since one mole of water is made up of 6.02 x 1023 molecules, in one gallon of water there are 1.266 x 1026 molecules.
That is: 126600000000000000000000000 molecules!
If we multiply that by the number of atoms in a single water molecule -- 3 atoms -- then we get:
379800000000000000000000000 atoms!
Answer:
Chemical weathering is the process by which rocks are broken down by chemical reaction.
Explanation:
Chemical weathering is the weakening and subsequent disintegration of rock by chemical reactions. These reactions include oxidation, hydrolysis, and carbonation. These processes either form or destroy minerals, thus altering the nature of the rock's mineral composition.
