Question 1

mixture

Answer 1

when elements and compounds physically combine

Question 2

heterogeneous mixture

Answer 2

unevenly mixed, can see individual components

-sand and water

Question 3

Answer 3

larger particles that are not dissolved

-shake well dressings

Question 4

homogeneous mixture

Answer 4

equally mixed, can’t see individual components

-cake batter

Question 5

solubility

Answer 5

ability to dissolve in other substances

Question 6

solvent

Answer 6

liquid that will dissolve particles

Question 7

solute

Answer 7

will be dissolved

Question 8

aqueous solution

Answer 8

dissolved in water

Question 9

synthesis reaction

Answer 9

2 reactants combine to make a new product

-A+B= AB

Question 10

decomposition

Answer 10

break down

-AB= A +B

Question 11

single replacement

Answer 11

an element in the compound replaces another element

-C+AB= AC + B

Question 12

double replacement

Answer 12

2 elements replace 2 other elements

- AB + CD= AD + BC

Question 13

combustion

Answer 13

requires fuel to burn, needs carbon and hydrogen and yields CO2, water and energy

Question 14

Acids

Answer 14

• ph of 1-6
• more H+ ions
• yogurt, detergent, soda, stomach acid

Question 15

bases

Answer 15

• ph of 8-14
• more OH- ions
• include soap, laxatives, oven cleaners

Question 16

Arrhenius theory

Answer 16

acids have at least one hydrogen atom that forms an hydronium ion when dissolved in water
-bases form OH- in water

Question 17

Bronsted-Lowry Theory

Answer 17

acids are H+ donors that increase concentration of hydronium ions
-bases are H+ receivers that increase hydroxide concentration

Question 18

lewis theory

Answer 18

acids are e- acceptor and bases are e- donors
