Answer:
The intermolecular forces between water molecules are stronger than those between oxygen molecules. In general, the bigger the molecule, the stronger the intermolecular forces, so the higher the melting and boiling points.
Answer:
Liquid: 38.7 g x 1 ml/0.865 g = ml of liquid
Vol of solid = 80.0 ml - ml of liquid
mass of solid = vol of solid x 2.75 g/ml
(100. g)

Answer:
1. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
2. Given below are some of the examples of the chemical reactions in our daily life:
Photosynthesis.
Combustion.
Aerobic cellular respiration.
Anaerobic respiration including the process fermentation.
Metathesis reactions, for example, vinegar and baking soda.
Oxidation which includes rusting.
Digestion.
3. A chemical formula is the combination of atomic symbols that designate a particular chemical compound, or a substance with two or more different elements. ... A chemical equation shows one or more chemical compounds (reactants) being converted into different chemical species called products.
