#1
Front (Question)

what’s the composition of the air?

Back (Answer)

nitrogen - 78 % oxygen - 21 % argon - 0.96 % carbon dioxide - 0.04 %

#2
Front (Question)

how can we measure the percentage of oxygen?

Back (Answer)

by reacting it with another element, and the air gradually decreases until all of the oxygen has been added to the element to work out the percentage: decrease in volume / initial volume of air x 100 = %

#3
Front (Question)

why do some experiments fail?

Back (Answer)

leak in apparatus wasn’t heated long enough for all the oxygen to be reacted

#4
Front (Question)

what affect mass?

Back (Answer)

heating on yellow flame as the door adds to mass not heating for long enough something has escaped

#5
Front (Question)

what is the equation for element combustion?

Back (Answer)

element + oxygen > element oxide

#6
Front (Question)

what affects the name and state of the oxide?

Back (Answer)

whether it is a metal or non-metal metal - oxide, solid non-metal - dioxide, gas

#7
Front (Question)

what’s important about the element combustion of magnesium?

Back (Answer)

produces a bright white light and white power

#8
Front (Question)

what’s important about the element combustion of sulphur?

Back (Answer)

blue flame

#9
Front (Question)

what’s important about the element combustion of hydrogen ?

Back (Answer)

#14
Front (Question)

what’s the charge of zinc?

Back (Answer)

Zn 2+

#15
Front (Question)

what’s the charge of lead?

Back (Answer)

Pb 2+

#16
Front (Question)

what’s the chemical test for oxygen?

Back (Answer)

glowing splint > relights as the oxygen allows the wood in splint to combust more efficiently
