Yes, compounds consist of elements that are combined in exact ratios by mass. This fixed proportion is what defines a compound and distinguishes it from mixtures, where components can vary in ratios. For example, water (H₂O) always has two hydrogen atoms for every one oxygen atom, maintaining a consistent ratio of 2:1.

What do compounds always contain exact ratios of?
elements
Do atoms combine to form molecules in simple whole number ratios?
They do combine in whole number ratios, but these ratios need not be simple - particularly in some organic compounds.
Is it true that the elemental composition of compounds is represented in whole number ratios?
Yes, it is.
What is meant by the law of constant composition for compounds?
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
What do aeronautical engineers use ratios and proportions for?
I'm sure they use ratios and proportions at many different points in the practice of their profession. One obvious application is in construction of exact scale models of aircraft and their components for wind-tunnel tests.
What do compounds always contain exact ratios of?
elements
What do compounds always contain in exact ratios?
Compounds always contain elements in exact ratios, based on the chemical formula of the compound. This means that the elements are present in specific and consistent proportions in the compound.
What do you compounds always contain exact ratios of?
Compounds always contain exact ratios of atoms, which are represented by their chemical formulas. These ratios indicate the number of each type of atom present in the compound, ensuring that the compound has a consistent composition. For example, water (H₂O) has a fixed ratio of two hydrogen atoms to one oxygen atom. This fixed ratio is characteristic of the specific compound and distinguishes it from mixtures.
What do compounds always conain exact ratios of?
Compounds always contain exact ratios of atoms of different elements. These ratios are defined by the chemical formula of the compound, which specifies the number of each type of atom present. For example, in water (H₂O), there are always two hydrogen atoms for every one oxygen atom, reflecting a fixed ratio. This consistent composition is fundamental to the identity and properties of the compound.
Do compounds usually have variable ratios where as mixtures usually have fixed ratios?
No, its the opposite. Compounds have fixed ratios, think of H20, while mixtures can vary. You can make many types of mixtures out of the same things. Because of bonding compounds have fixed ratios.
What the relationship between the elements and the compounds?
Atoms make up all matter. An element has atoms that are all the same. Compounds are made of different kinds of atoms combined chemically in exact whole number ratios.
How are ratios classified?
Ratios are often classified using the following terms: profitability ratios (also known as operating ratios), liquidity ratios, and solvency ratios.
Do different mass ratios mean different compounds?
No
Do mixtures contain exact ratios of elements?
No, they do not.
Do elements that combine in changing ratios form mixtures?
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
Do atoms combine to form molecules in simple whole number ratios?
They do combine in whole number ratios, but these ratios need not be simple - particularly in some organic compounds.
What do you get with changing ratios that combine in elements?
In this mode different compounds are obtained.
