What else can I help you with?
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.
Do gases always have a definite volume for a given mass?
no, it depends on pressure and temperature as well
Matter that has a definite volume and a definite mass is?
Matter that has a definite volume and a definite mass is... a SOLID. So any solid will be a correct answer to your question.
Which have definite mass and volume but no definite shape?
Liquids have a definite mass and volume, but not a shape.
Does liquid have definite mass?
Yes, liquid has a definite mass. Mass is a measure of the amount of matter in an object, and liquids, like all forms of matter, have mass. The mass of a liquid is determined by the density of the liquid and the volume of the liquid. The mass of a liquid can be measured using a balance or a scale.
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.
The scientific statement that says that compounds always have exactly the same composition by mass is?
The law of definite proportions states that compounds always contain the same elements in the same proportion by mass. This means that the ratio of elements in a compound is consistent and does not change.
What statement best supports the law of definite proportions?
Pure water is always 11.2% H, and 88.8% 0 by mass
Examples of the law of definite composition?
The law of definite composition states that chemical compounds always contain the same elements in the same proportions by mass. For example, water always consists of two hydrogen atoms and one oxygen atom in a 2:1 ratio by mass. Additionally, carbon dioxide always contains one carbon atom and two oxygen atoms in a 1:2 ratio by mass.
Does solid has definite mass and space?
A solid has a mass
Does a Soild have a definite shape mass and volume?
Solids do have definite volume, as it is always the same shape anywhere, even in space, but not the same mass, as 1 pound on earth is a lot less on the moon. Hope this helps a bit. '''Oops''', there is a slight mistake in the above answer - a very common mistake among students of basic physics. Mass and weight are not the same thing. Mass is the amount of substance an object contains and is the same no matter where the thing is, earth or moon. Weight, on the other hand, is measured by the gravitational pull on the object and changes from one planet to another. Therefore, solids have a definite (fixed) volume '''and''' mass.
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.
