Fats are made of the same elements as carbohydrates, but in different proportions.
Because the proportions of the elements are different in the different compounds. They may contain the same elements, but the different proportions make them different compounds with different properties.
The difference could be in the proportions of the elements or in the structure of the compounds There are three iron oxides where the proportions of the elements are different, FeO, Fe2O3, Fe3O4 There are two isomers of butane C4H10 , two structural forms, n-butane and iso-butane.
COMPOUNDS.
These things were considered by the Ancient Greeks to be the elements which made up (in different proportions) all matter.
Two or more chemcal elements combined in constant proportions.
Fats are made up of Carbon and hydrogen atoms.
its schrodinger
A substance made from two or more elements in definite proportions. eg NaCl
All elements that occur in nature occur on Earth, the Sun, and the Moon - but the proportions are different. The main difference is that the Sun is made up mainly of hydrogen and helium; both are relatively scarce on Earth and on the Moon.
All elements are made of atoms.
He deduced that from the law of definite proportions.
Rocks are made up of minerals. Different rocks consist of different minerals in different proportions.
