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 is the difference between stoichiometric and non stoichiometric solids?
Non-stoichiometric compounds are chemical compounds with an elemental composition that cannot be represented by a ratio of well-defined natural numbers.Stoichiometric compounds are compounds in which atoms are combined in exact whole-number 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.
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.
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 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.
Do elements that combine in changing ratios form mixtures?
No, compounds are formed.
What do you get with changing ratios that combine in elements?
In this mode different compounds are obtained.
When do two ratios form a proportion?
When both can multiply its comparisons to when both ratios share the exact same numbers.
What is the relationship between atoms elements and compounds?
I believe...compounds are made up of two or more elements. Elements are made up of atoms.
