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 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?
Yes, compounds have fixed ratios of elements in a chemical formula, whereas mixtures can have variable ratios of different substances mixed together. Compounds are chemically bonded, while mixtures are physically mixed.
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.
When do two ratios form a proportion?
When both can multiply its comparisons to when both ratios share the exact same numbers.
What do you get with changing ratios that combine in elements?
In this mode different compounds are obtained.
What is the relationship between element and compound?
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.
