Not necessarily
No, compounds do not always contain the same elements in the same ratio. Compounds are formed by the combination of two or more elements in fixed proportions by mass. The ratio of elements in a compound is determined by the chemical formula of the compound.
True. Compounds do not have the same properties as the elements that form them.
They are not. The same
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.
Elements combined in specific ratios form compounds.
No, compounds and elements are not always solids. For example, hydrogen is a gas.
a compound always has the same chemical formula
True. Compounds do not have the same properties as the elements that form them.
Organic compounds always contain Carbon and Hydrogen. Most organic compounds contain elements like Oxygen,Nitrogen,Phosphorus and sulphur. Organic compounds are found in living things.
elements
If two elements have similar electronegativities or valence electron configurations, they are more likely to bond with the same element in the same proportion. This is because they share similar chemical properties, making them compatible in forming compounds with the same ratios of atoms. This principle is exemplified in the Law of Definite Proportions, which states that compounds always contain the same elements in the same proportion by mass.
Having a fixed composition means that a substance always contains the same elements in the same proportion by mass. This characteristic is a defining feature of pure substances like elements and compounds.
