What does a chemical equation have?
It contain the chemical formula of the specified compounds (reactants and final products), it contains the chemical proportions of a compound (coefficients).
Every chemical compound is unique and different from the it contains.?
Every chemical compound is unique and different from the ELEMENTS it contains
Why is the law of definite proportion important.?
In chemistry, the law of definite proportions, sometimes called Proust's Law, states that a chemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition by mass. For example, oxygen makes up about 8/9 of the mass of any sample of pure water, while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry.
Laws of chemical conbination?
The laws of chemical combination are fundamental principles that govern the relationships between the quantities of reactants and products in a chemical reaction. The three main laws are the law of conservation of mass, the law of definite proportions, and the law of multiple proportions. The law of conservation of mass states that mass is conserved in a chemical reaction, meaning that the total mass of the reactants is equal to the total mass of the products. The law of definite proportions states that a compound always contains the same proportions of elements by mass. The law of multiple proportions states that when two elements combine to form multiple compounds, the mass ratios of the elements in the compounds are always in whole-number ratios.

Describes what elements are in a compound and in what proportions?
The particular elements and their proportions depend on what the compound is, for example Water contains Hydrogen and Oxygen which Salt contains Sodium and Chlorine.
The law of definite proportions states that a compound always contains the same elemtents in the smae proportions?
true
Is sulfur trioxide an element compound or mixture?
Sulfur trioxide is a compound, because it always contains sulfur and oxygen in the same proportions to each other and features inter atomic chemical bonds.
