The statement that a chemical compound always contains the same elements in exactly the same proportions is called the law of?
"In chemistry, the law of definite proportions and also the elements, sometimes called Proust's Law, states that a chemical compoundChemical_compoundalways contains exactly the same proportion of elementsChemical_elementby 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." - Wikipedia
A chemical property is a change in what?
There are many different possible property changes in a chemical change. You must post the specific reaction for anyone to tell you exactly.
When each side of a composition is exactly the same it shows?
When each side of a composition is exactly the same, it shows symmetry. This creates a sense of balance and order in the design.
What is a method for showing what a molecule or compound contains?
Chemical analysis shows the contents of compounds and molecules. To identify the compound, you use qualitative analysis. To know exactly how much is present, quantitative analysis should be performed.
What is matter that always has exactly the same composition classified as?
I believe it is an element.
Why is hot soup cooling down a physical change?
The chemical composition remain unchanged.
When ice melts you can tell it is a chemical change because?
The melting of ice is a physical not, not a chemical change. You can tell this because the chemical composition of ice and water are exactly the same, i.e. they are both H2O. Only the physical property has changed since one is a solid and one is a liquid.

How does a Salmon know exactly where they were born?
They 'imprint' the chemical composition of the stretch of water where they hatch. Once they reach adulthood (after swimming in the oceans) they use this imprinted knowledge to 'home in' on the river where they hatched.

Is brushing your teeth a chemical change?
It's a physical action without toothpaste. Many toothpaste have inactive ingredients, and are only there to "taste good". Toothpaste with fluoride, baking soda, and other common dental ingredients will undergo small chemical changes when they come in contact with water (when baking soda in water come together it creates a chemical reaction). So in some respects it's both!
What exactly are water particles?
particles made up of 2 hydrogen n 1 oxygen
What is the chemical name for actinium?
The official chemical name is exactly actinium.
What is the definition of pure substances?
A pure substance is a substance that consists solely of the same atoms/molecules.So a volume of water that contains only H2O is a pure substance. A block of iron that contains only Fe atoms is pure substance. A pure substance can be composed of atoms or molecules as I said before BUT they have to be exactly the same.A substance that has constant chemical composition and characteristics
What is matter that always has exactly the same composition classified as?
I believe it is an element.
