I think you forgot to attach a picture
A compound is where two or more elements have chemically bonded, and a mixture is where there are two or more elements are grouped together, but they are not chemically bonded.
An example of a mixture would be salt dissolved in water, and an example of a compound would be water (which is made up of 2 Hydrogen and 1 Oxygen bonded together)
tl;dr: I would go with B, basically.
The compound with a chemical formula of C₃H₈ is propane. The subscripts actually represent the number of the individual atoms in 1 particle of the compound. Since there are the same number of atoms per mole of any substance, the subscript can also represent the moles. Through stoichiometric calculations, the solution is as follows:
Moles of Carbon = 11.2 moles H * 3 mol C/8 mol H = <em>4.2 moles</em>
Answer:
<h3>The answer is 0.81 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 10.5 g
volume = 13 cm³
We have
We have the final answer as
<h3>0.81 g/cm³</h3>
Hope this helps you
