Does a mineral contains certain elements in definite proportions?
Yes
When geologist say that a mineral always contains certain elements in the definite proportions they mean that the mineral has a definite?
A chemical formula.
Is there fowlloing sentence true or false?
A mineral always contains certain elements in definite proportions
Is it true that a mineral always contains certain elements in definite proportions?
Yes, minerals have a specific chemical composition, meaning they contain certain elements in definite proportions. This is a characteristic feature of minerals that distinguishes them from other natural substances.
Does a mineral always contain certain elements in definite proportions?
No, a mineral does not always contain certain elements in definite proportions. While minerals have a specific chemical composition, the proportions of elements can vary within certain limits and still be considered the same mineral.
When geologists say that a mineral always contains certain elements in definite proportions they mean that the mineral always has what?
When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
Is the sentence true or false each piece of mineral has the same crystal structure?
that question iz absolutely trueFalse
Does a mineral always contain certain elements definite composition?
yes
Why do elements join to form compounds in specific ratios?
Elements combine according to the electrons in their outer shell. These allow only certain combinations which form a ratio. Oxygen has 2 + in its outer shell. Hydrogen has 1 - in its outer shell. So the ratio is always 2:1.
What do scientists use to calculate the age of an object by measuring the proportions of the radioactive isotopes of v equals certain elements?

Who wrote the law of definite proportions and Law of multiple proportions?
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
What do Chemical composition describes?
"chemical composition" is talking about the individual chemicals that make up a substance. The chemicals it is composed of. eg, wood is mainly carbon, with some water (which is hydrogen and oxygen) and various minerals.
