Front (Question)

How reactivity determined for metals?

Back (Answer)

Reactivity is determined how easily they lose electrons

Front (Question)

The higher up a metal is in the reactivity series means…

Back (Answer)

The more easily it’ll form positive ions (and the more easily it’ll react with water or acid)

Front (Question)

What happens when metals react with water or an acid?

Back (Answer)

They lose electrons and form positive ions

Front (Question)

Metals below hydrogen in the reactivity series will…

Back (Answer)

Not react with acid

Front (Question)

Metals above hydrogen in the reactivity series will…

Back (Answer)

React with acids

Front (Question)

How can metals that are less reactive than carbon be extracted from their ores?

Back (Answer)

By reduction with carbon

Front (Question)

How can metals that are more reactive than carbon be extracted from their ores?

Back (Answer)

Using electrolysis

Front (Question)

Recite the reactivity series

Back (Answer)

Potassium Sodium Lithium Calcium Magnesium Carbon Zinc Iron Hydrogen Copper

Front (Question)

Acid + Metal →

Back (Answer)

Salt + Hydrogen

#10

Front (Question)

Metal + Water →

Back (Answer)

Metal Hydroxide + Hydrogen

#11

Front (Question)

How will very reactive metals (potassium, sodium, lithium, calcium) react with acid?

Back (Answer)

They’ll react explosively

#12

Front (Question)

How will less reactive metals (magnesium, zinc, iron) react with acid?

Back (Answer)

Less violently (than very reactive materials)

#13

Front (Question)

Will copper react with cold, dilute acid?

Back (Answer)

#14

Front (Question)

The more reactive metal is, the ____ the reaction will go

Back (Answer)

faster

#15

Front (Question)

What is the speed of reaction (metal + acid) indicated by?

Back (Answer)

Rate of the bubbles of hydrogen given off

#16

Front (Question)

What metals will react with water?

Back (Answer)

Reactive metals like potassium, sodium, lithium & calcium

#17

Front (Question)

What metals will not react with water?

Back (Answer)

Less reactive metals like zinc, iron & copper

#18

Front (Question)

How does magnesium react with cold, dilute acid?

Back (Answer)

Vigorously and produces a lot of bubbles

#19

Front (Question)

How does zinc and iron react with cold, dilute acid?

Back (Answer)

Fairly slowly (speed up if heated)

#20

Front (Question)

How can smelting be used to obtain copper?

Back (Answer)

Heat copper ores in a furnace to extract high concentrations of copper

#21

Front (Question)

What is an advantage of smelting?

Back (Answer)

Get large amounts of copper

#22

Front (Question)

What is a disadvantage of smelting?

Back (Answer)

Time consuming

#23

Front (Question)

How can bioleaching be used to obtain metal?

Back (Answer)

Uses bacteria to produce leachate solutions that contain metal compounds

#24

Front (Question)

What is an advantage of bioleaching?

Back (Answer)

• More simpler/cheaper to operate/maintain • Environmentally friendly
