8 0

Answer:

20 moles

Explanation:

we are given the equation, propane is C3H8. I'll put 1 in front of C3H8 to show you the ratios. The right side of the equation is not needed.

1C3H8+ 5O2

1 : 5

4 moles : x moles

working out x:

to get from 1 to 4 in C3H8 multiply by 4, so do the same to the other side for O2

5 × 4 = 20, so 20 moles are necessary to react completely with four moles of propane

A gravel can be broken down into different kinds of substances by physical processes. No chemical reactions are needed to separa
Vlada [557]

Answer:

MIXTURE

Explanation:

A mixture is a substance composed of a combination of other different substances. These component(s) of a mixture are physically combined, meaning that there is no chemical linkage between the individual components/constituents of a mixture.

This is the case of the gravel described in this question. The components of gravel can be separated using physical means because they are not chemically bonded to one another, hence, no chemical reactions are needed to separate different parts of gravel into pure substances. This makes gravel a MIXTURE.
