Front (Question)

what happens when the indicator Blue Litmus paper enters an acid, neutral or base solution

Back (Answer)

acid- turns red neutral- nothing happens base- nothing happens

Front (Question)

what happens when the indicator Red Litmus paper enters an acid, neutral or base solution

Back (Answer)

acid- nothing happens neutral-nothing happens base- turns blue

Back (Answer)

acid-turns yellow neutral- turns green base-turns blue

Front (Question)

properties of acids

Back (Answer)

-taste sour -ph less then 7 -do not feel slippery -Release hydrogen ions (H+) in aqueous solution -reacts with metal to produce a compound and hydrogen gas

Front (Question)

properties of bases

Back (Answer)

-taste bitter -does feel slippery -ph greater then 7 -release hydroxide ions (OH-) in aqueous solution -does not react w metals

Front (Question)

common properties of acids and bases

Back (Answer)

-dissolve in water -conduct electricity in aqueous solution -can irritate or burn skin -both acids and bases dissolve in water and create anions

Front (Question)

how do bonds form when something is ionic

Back (Answer)

electrons are transferred

Front (Question)

how do bonds form when something is covalent

Back (Answer)

electrons are shared

#10

Front (Question)

state of something ionic and what does it consists of

Back (Answer)

-consists of ions -hard but brittle -solid at room temp -odourless -crystal lattice

#11

Front (Question)

state of something covalent and what does it consists of

Back (Answer)

-consists of molecules -solid, liquid or gas at room temp -sometimes have odour

#12

Front (Question)

melting/boiling point of something ionic

Back (Answer)

high melting and boiling point due to strong electrostatic

#13

Front (Question)

melting/boiling point of something covalent

Back (Answer)

low melting and boiling point

#14

Front (Question)

solubility of something ionic

Back (Answer)

-many are soluble from electrolyte solution when dissolved in water

#15

Front (Question)

solubility of something covalent

Back (Answer)

-sometimes soluble -from non-electrolyte solutions

#16

Front (Question)

conductivity of something ionic

Back (Answer)

-conductive -ions allow electricity to flow

#17

Front (Question)

conductivity of something covalent

Back (Answer)

-not conductive -no ions formed

#18

#19

Front (Question)

what is multivalent

Back (Answer)

any of the multivalent ions example: tin, lead, manganese

#20

Front (Question)

what is binary covalent

Back (Answer)

2 non-metals

#21

Front (Question)

what is ionic

Back (Answer)

metal+non-metal+ ide

#22

Front (Question)

Formula for Synthesis

Back (Answer)

A+B —> AB Element+ Element —> Compound

#23

Front (Question)

Formula for decomposition

Back (Answer)

AB ——> A+B Compound —> Element+ Element

#24

Front (Question)

formula for single displacement

Back (Answer)

If a metal is sitting by it’s self as an element it get’s switched with the other metal in the compound, same thing with non-metals
