Answer:
1. Many different hypotheses will be tested.
Explanation:
Scientists test every hypothesis they make for their investigation, before moving onto bigger conclusions.
I believe the four classifications of matter would be:
- element
- compound
- homogenous mixture
- heterogeneous mixture
And then the two pure substances would be element and compound.
Answer: Water and acetone
Explanation: you will find that the water and the soil are polar opposite, while the principal component of the water are Hydrogen and Oxygen, in the acetone you will find a change of carbon, the components from each molecule confer to each one specific physical properties for example the boiling point, and the distillation is a physical separation based on the boiling point.
then you can find the boiling point of the water in 100 °C, and the boiling point of the acetone is 56 °C, this give as a difference of 44 °C,
then while the acetone is boiling the water is liquid state, and this give us the opportunity to the separate the acetone in gas state by condensation after the boiling.
