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 figure does equal measures of ratios with equal angle measures make?
oh my god
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
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.
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.
What is matter made of elements combined in changing ratios?
You think probable compounds.
What forms a compound?
Atoms of elements combine in fixed ratios will form compounds.
Is it true that the elemental composition of compounds is represented in whole number ratios?
Yes, it is.
Which scientist observed that compounds are always joined together in fixed ratios?
Niels Bohr
What is matter made of element combined of changing ratios form?
You think probable compounds.
