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 do you think ratios are used in paint mixtures?
Ratios are used in paint mixtures to determine the correct proportions of different ingredients, such as pigment, binder, and solvent. These ratios ensure consistency and quality in the final paint product. By following a specific ratio, artists and manufacturers can create paint colors with the desired properties, such as opacity, drying time, and durability.
Do atoms combine in only one-to-one ratios to form compounds?
No, this affirmation is not correct.
What is matter made of element combined in changing ratios form?
You think probable compounds.
Do the atoms in a mixture have a set ratio?
Atoms can interact in different manners. Compounds can have the same ratios of atoms combined in different ways producing different properties (cis and trans forms of compounds come to mind). Additionally, many compounds consist of the same elements but in different ratios. Compare Carbon dioxide, a inert waste product of respiration, to carbon monoxide, a gas deadly to humans. Both use carbon and oxygen, but CO2 has an extra oxygen molecule, greatly changing its properties. So in short, no. Atoms can combine in multiple ratios, and even compounds of equal ratios can come together in different manners to produce different compounds.
What type of matter is made of elements in a specific ratio that is always the same?
Elements combined in specific ratios form compounds.
Do elements that combine in changing ratios form mixtures?
No, compounds are formed.
Can a compound be heterogeneous?
No, a compound cannot be heterogeneous. Compounds are constant with fixed ratios, while heterogeneous mixtures have separate dissimilar substances that you can see.
Is calcium hydroxide a metal?
No: Calcium by itself is a metal, but calcium hydroxide is a compound, and compounds are never metals. Note, however, that mixtures of metals, usually called alloys, do exist and are metallic. These alloys are not compounds because they do not have fixed compositions that are the ratios of small whole numbers of atoms of each constituent.
Do mixtures contain exact ratios of elements?
No, they do not.
Is lead oxide consider as a metal?
No: Lead by itself is a metal, but lead oxide is a compound, and compounds are never metals. Note, however, that mixtures of metals, usually called alloys, do exist and are metallic. These alloys are not compounds because they do not have fixed compositions that are the ratios of small whole numbers of atoms of each constituent.
Mixture are combined in definite ratios?
No, this depends on the recipe for artificial mixtures and on the hazard for natural mixtures.
What are the properties of mixture?
Mixtures contain two or more compounds associated without chemical bonds. Mixtures are homogeneous or heterogeneous. Several mixtures can be separated by physical procedures. Mixtures can have 1, 2 o3 phases.
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.
What do you get with changing ratios that combine in elements?
In this mode different compounds are obtained.
