Combustion

Question 1

Combustion

Answer 1

a reaction in which a substance reacts with oxygen, releasing energy in the form of light and heat

Question 2

What does combustion usually result in

Answer 2

burning or explosion

Question 3

Complete combustion

Answer 3

when all the oxygen in reactions are used up

Question 4

Why are fuels combustion reactions

Answer 4

they have enough oxygen to make carbon dioxide.

Question 5

what does the release of carbon dioxide do

Answer 5

adds to the
greenhouse effect and global warming

Question 6

combustion reaction equation

Answer 6

fuel + oxygen 🡪 carbon dioxide + water

Question 7

Incomplete combustion

Answer 7

When the air supply is limited, carbon monoxide can be produced instead of
carbon dioxide.

Question 8

Incomplete combustion equation

Answer 8

Fuel + limited oxygen 🡪 carbon monoxide+carbon+water

Question 9

How is carbon released in an incomplete combustion reaction

Answer 9

as a soot(black powder)

Question 10

How does carbon monoxide affect humans

Answer 10

poisonous

Question 11

products of a complete combustion

Answer 11

Carbon dioxide and water

Question 12

products of an incomplete combustion

Answer 12

Carbon monoxide + carbon + water

Question 13

hydrocarbon

Answer 13

type of compound that combust extremely well.

Question 14

hydrocarbon examples

Answer 14

Coal, petrol, natural gas

Question 15

how are exothermic reactions related to combustion reactions

Answer 15

both reactions release heat

Question 16

why do some fires produce smoke

Answer 16

when there is an incomplete combustion(not enough oxygen to burn the fuel completely)

Question 17

example of complete combustion

Answer 17

Burning candle wax

Question 18

example of an incomplete combustion

Answer 18

burning paper

Question 19

corrosive

Answer 19

the ability of a substance to destroy every material it comes in contact with

Question 20

concentration

Answer 20

measure of the amount pf hydrogen ions in an acid or hydrozide ions in a base
