Reactivity

Question 1

how and why do we store group 1 metals

Answer 1

we store group 1 atoms in oil bcz they react vigorously with air and moisture so they can explode

Question 2

what happens to group 1metals after coming out of container

Answer 2

when we see it is dull when pieces are cut they are shiny but soon they also become dull as they are very reactive to oxygen and a oxide of metal is formed

General equation metal + oxygen = metal oxide

Question 3

how to group metals react with water

Answer 3

lithium reacts with to produce hydroxide and hydrogen very slowly
sodium is more reactive than lithium in water
potassium is more reactive so much that it generates head that hydrigen gas catches fire

Question 4

how metals react with steam

Answer 4

a cotton cloth has been soaked and magnesium is gets heated time to time this makes the wet cloth produce steam and reaction carries out between magnesium and steam which produces metal oxide +steam

Question 5

Give an example on metal reacting to dilute acid and write the word equation

Answer 5

magnesium chloride is a salt a when metal and acid react salt is formed
word equation is magnesium + hydrochloric acid = magnesium chloride+ hydrogen

Question 6

name the reactivity series

Answer 6

gambler sold coke large in zoo and money came so plenty

Question 7

what is a displacement reaction and which colour the solution changes ive an example and write a word equation for it

Answer 7

a disPLACEMENT REACTION IS WHEN STRONGER METAL displaces or pushes out a weaker metal an example is copper Sulfate + iron = Ironsulfate + copper the solution changes blue and iron was more stronger than copper so it pushed it out

Question 8

explain displacement using carbon

Answer 8

carbon will displace zinc,iron,tin,lead from their ores . a ore is a rock that contains metal compund
iron oxide +carbon =iron +carbon dioxide
