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).
What is always true of a binary compound?
A binary compound always contains two different elements. This means it will have a chemical formula consisting of two elements in fixed proportions. Binary compounds typically involve a metal and a nonmetal.
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?
A compound is a substance composed of two or more elements chemically bonded in fixed proportions. The elements in a compound are present in set ratios determined by the compound's chemical formula. Each compound has a unique combination of elements and proportions that define its chemical properties.
What is the law of proportions?
A chemical compound always contains exactly the same proportion of elements by mass. ---------------------------------------------------------------------------------------------------- A law that states that a compound always contains the same elements in the same proportions. Source: e2020
Who said that a given compound always contains the same elements in the same proportions by mass?
This statement was made by French chemist Joseph Proust and is known as the Law of Definite Proportions. It states that a compound always contains the same elements in the same proportions by mass regardless of the source of the compound.
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).
What is hydrogen compound?
It is a type of chemical compound that contains the element Hydrogen. Chemical compounds are molecules of two or more elements in fixed proportions. Ex. CH4
State the law of definite proportions?
The law of definite proportions states that a compound always contains the same elements in the same proportion by mass, regardless of the source of the compound. This means that for a given compound, the ratio of the masses of the elements is always constant.
What is the law of definite proportions?
The law of definite proportions states that a compound always contains the same elements in the same proportion by mass. This means that the ratio of the masses of the elements in a compound is constant. This law is one of the fundamental principles of stoichiometry in chemistry.
What is the law that states that a chemical compound always contains the same elements in exactly the same proportions by w eight and mass?
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.

Is fresh squeezed lemonade a mixuture?
Yes: It contains more than one chemical compound, and different samples of lemonade have different proportions among the ingredients.
