What are the four properties of water?
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends.

What is the chemical make up of oxygen?
Oxygen has two allotropic forms, diatomic (O2) and triatomic (O3, ozone). The properties of the diatomic form suggest that six electrons bond the atoms and two electrons remain unpaired, accounting for the paramagnetism of oxygen. The three atoms in the ozone molecule do not lie along a straight line.
What is molecular weight of oxygen?
15.999 u
What is the molecular weight of glucose?
180.156 g/mol
What is the molecular weight of MG?
24.305 u
What is molecular weight explain with examples?
The sum of the atomic masses of all atoms in a molecule, based on a scale in which the atomic masses of hydrogen, carbon, nitrogen, and oxygen are 1, 12, 14, and 16, respectively. For example, the molecular weight of water, which has two atoms of hydrogen and one atom of oxygen, is 18 (i.e., 2 + 16).
What is the difference between formula weight and molecular weight?
The formula mass (formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula. The molecular mass (molecular weight) of a molecule is its average mass as calculated by adding together the atomic weights of the atoms in the molecular formula.
What is the formula of equivalent weight?
The equivalent weight of an element is its gram atomic weight divided by its valence (combining power). Some equivalent weights are: silver (Ag), 107.868 grams (g); magnesium (Mg), 24.312/2 g; aluminum (Al), 26.9815/3 g; and sulfur (S, in forming a sulfide), 32.064/2 g.
What are the properties of oxalic acid?
Physical properties: Oxalic acid is an odorless, crystalline white solid with density of 1.9 g/mL and melting point of 190 °C. It is commonly found in the hydrate form (COOH)2 · 2H2O. It is water soluble and forms a colorless and acidic solution in water.
