mixtures

Question 1

Matter is classified into 2 branches which are?

Answer 1

Mixtures and Pure Substances

Question 2

Formed when elements and/or compounds are combined physically. It is matter that can vary in composition. Properties of this type of matter are related to its components.

Answer 2

Mixtures

Question 3

What are the main types of mixtures?

Answer 3

Homogeneous and Heterogeneous

Question 4

How can you tell the difference of a Homogeneous and a Heterogeneous?

Answer 4

A homogeneous is evenly mixed, it is evidently seen in its particles and it always has a solute and a solvent. A heterogeneous is not evenly mixed and most of these mixtures can be seen physically and a heterogeneous can have different types of combinations BUT it still is the same

Question 5

What is the difference of a Pure Substance and a Mixture?

Answer 5

A pure substance has a fixed composition while mixtures do not. Pure substances can only be separated by chemical means while mixtures can be separated physically.

Question 6

Factors that affect the rate of dissolving

Answer 6

Temperature and Pressure

Question 7

This usually has a solute and solvent and is a homogeneous mixture

Answer 7

Solution

Question 8

Name and briefly explain the 3 different types of solutions

Answer 8

Saturated- contains maximum amount of solute but it can still hold in a given temperature and pressure.
Unsaturated- can still dissolve more solute at a given temperature
Super-Saturated- contains more than the maximum solute which then becomes a supersaturated solution because when you add more solute, it becomes unstable and makes crystals.

Question 9

It is a type of mixture which in the individual substance isn’t evenly mixed and different samples of this mixture can have different combinations but still the same substance.

Answer 9

Heterogeneous

Question 10

Define the a “suspension”

Answer 10

a heterogeneous mixture which the particles will settle out upon standing. An example is sand and water

Question 11

It is a homogeneous/heterogeneous (depending on the source) mixture whose particles are medium sized and will not settle upon standing

Answer 11

Colloids

Question 12

Expound and explain the “Tyndall Effect”

Answer 12

This experiment has a visible path that is produced by a beam of light. That light will pass through a colloidal and a suspension substance. It is caused by the scattering of light by the dispersed particles. It can make you identify if a substance is a colloid, a solution or a suspension since the light beam would only push though when it is a colloid or suspension.
