Law of Definite Proportions states that a compound is composed of the same ratio of elements present. The formation of water has a reaction:
H2 + 1/2 O2 = H2O
The limiting reactant would be the element with the least ratio of molar mass to stoichiometric coefficient, and that would be H2, not O2.
Answer:
Lungs
Explanation: The two organ systems that work together to provide the cells with oxygen and remove carbon dixoide from the body are the lungs.
There are O-H bonds in H2O. They have the intramolecular force of polar covalent bond.
Answer: Antoine Lavoisier.
He classified the elements into four groups: elastic fluids, nonmetals, metals and earths. Some of the called elementes were not really elements (light and heat). Others were compounds, e.g. hydrochloric acid.
An insoluble solid formed during a reaction is called a Precipitate.
