Question 1

are made up of two or more substances which are mixed chemically combined

Answer 1

Mixture

Question 2

has only one phase and a uniform composition all throughout (ex Water & salt)

Answer 2

Homogeneous mixture

Question 3

a homogeneous mixture composed of Solute & solvent

Answer 3

solution

Question 4

a substance that is being dissolved (salt)

Answer 4

solute

Question 5

the dissolving medium (water)

Answer 5

solvent

Question 6

DIFFERENT TYPES OF SOLUTION

Answer 6

1. Solid-solid solution
2. Solid-in-Liquid solution
3. Liquid-Liquid solution
4. Gas-liquid solution
5. Gas-gas solution

Question 7

two or more solids are combined to form of mixture. An example of this is an alloy.

Answer 7

Solid-solid solution

Question 8

the solute (the avortance that is dissolved) is inchid acid form while the solvent (the substance that dissolves the solute) is in liquid form.

the solid dissolves in the liquid because they have the same molecular property

Answer 8

Solid-in-Liquid solution

Question 9

two or more liquids are mixed to create a solution in liquid form

An example of this is water and alcohol

Answer 9

Liquid-Liquid solution

Question 10

involves the combination of a gas and a liquid

Example: a carbonated drink, soda, beer Carbonated drinks are in liquid form. but contain dissolved garer which from bubbles when the bottled gas released

Answer 10

Gas-liquid solution

Question 11

combination of two or more gases combined

Answer 11

Gas-gas solution

Question 12

has two or more phares

does not have a uniform composition

are substance can be separated from the other

Answer 12

Heterogeneous mixture

Question 13

are heterogeneous mixture that have particles bigger than those of a solution but smaller than the suspension

Answer 13

Colloids

Question 14

mixture distributed in dispersal medium

Answer 14

dispersal phase

Question 15

substance used by dispersal phase

Answer 15

dispersal medium

Question 16

have gas as the dispersed medium. and the dispersed phase is either solid or liquid

Answer 16

aerosols

Question 17

are mixtures of two or more liquids that are immiscible or cannot attain homogeneity

Answer 17

Emulsions

Question 18

are colloids in which a gas is dispersed into a solid or liquid

Answer 18

foams

Question 19

are colloids having solid as the dispersed ase and solid or liquid as the dispersed medium.

Answer 19

sols

Question 20

are heterogeneous mixtures that have partides bigger than those colloids..
They contain solid particles which eventually settle after interacting with a solvent-like phare

Answer 20

Suspensions

Question 21

reper to how clore the measured value is relative to a standard value

Answer 21

accuracy

Question 22

refers to how close to one another the Treasured value in a series are.

Answer 22

precision

Question 23

pertain to the digits or Figures that are certain to give reasonably reliable information

Answer 23

significant figures

Question 24

Rutes in Determining Significant Figures

Answer 24

1. all non-zero digits (1-9) are significant
2. Zeros to the left of first non-zero digit are not significant
3. Zeros between non-zero digits are significant
4. zeros to the right of a non-zero digit with a decimal point are significant
5. zeror at the end of a non-zero digit without a decimal point are not significant

Question 25
