The Reactivity Series Of Metal

Question 1

does metal react?

Answer 1

yes - Red-brown glows red and black layer tones

Question 2

does Iron react?

Answer 2

yes - grey wool burns with orange sparks and black solid tones

Question 3

does magnesium react?

Answer 3

yes - grey solid burns with a bright white light produces a white ash

Question 4

does zinc react?

Answer 4

yes - grey solid burns with a bright white light produces a white ash

Question 5

does aluminum react?

Answer 5

yes - sheets of aluminum do not burn easily. However, powdered aluminum and burns and a white solid tones

Question 6

does calcium react?

Answer 6

yes - Grey solid burns with a brick red flame, a white solid tones

Question 7

what is the general equations for burning metals in oxygen and word equations for burning any metals in oxygen?

Answer 7

• Magnesium + Oxygen= magnesium oxide*
  Iron + oxygen= Iron oxide
  Calcium + Oxygen= Calcium oxide
  *Copper + Oxygen= copper oxide *

Question 8

reaction: Na (Sodium)

Answer 8

*Floats on surface
*Metal melts into a ball
* gives off a gas/fizzes
*Metal disappeared
*Colorless solution form

Question 9

reaction: K (Potassium)

Answer 9

*Burns with a lilac flame. Floats on a surface
*Metal melts and forms a silvery ball.
*Gives off gas/fizzes. Disappears and forms a colorless solution

Question 10

reaction of Ca (Calcium) with Water

Answer 10

*Calcium + Water= Calcium hydroxide + hydrogen (also called limewater)
*Limewater is used to test for carbon oxide

Question 11

Calcium + Water

Answer 11

*Sinks and rises
*Bubbles of gas produced/fizzy/effervescence
*Gas burned with a pop
*Calcium disappeared to form a cloudy white/ milky solution
*Test tube warms up, heat is given out

Question 12

Testing the filtrate

Answer 12

*Filtrate is colorless
*Filtrate turns pH paper blue
*Solution turns milky white when bubbles of carbon dioxide pass through it

Question 13

General word equations

Answer 13

*Metal + Water= Metal hydroxide + hydrogen
*Sodium + Water= Potassium hydroxide + hydrogen
*Calcium + water= Calcium hydroxide + hydrogen

Question 14

General equations for reacting metals with steam

Answer 14

Magnesium + Steam= magnesium oxide + hydrogen
(grey solid) (white ash) (colorless gas)
( test for hydrogen using a lighted splint*)
Iron and zinc will react with steam and the observations are the same.

Question 15

Is Mg hydrogen produced and what is it’s reactivity scale?

Answer 15

bubbles of gas, grey solid disappeared, test tube warm, colorless solution formed= yes = 1

Question 16

Is Zn hydrogen produced and what is it’s reactivity scale?

Answer 16

bubbles of gas, slow reaction, test tube warm = yes = 2

Question 17

Is Cu hydrogen produced and what is it’s reactivity scale?

Answer 17

No reaction = no = =4

Question 18

Is Fe hydrogen produced and what is it’s reactivity scale?

Answer 18

bubbles of gas, very slow reaction = yes = 3

Question 19

Is Al hydrogen produced and what is it’s reactivity scale?

Answer 19

no reaction = no ==4
