Answer 7

Heating, oxidation, cooking with gas stove, intenal combustion engine of car, cellular respiration, burnt wax on a candle, petrol of car burning

Question 8

When does complete combustion occur?

Answer 8

Fuel reacts when there is lots of oxygen available

Question 9

Answer 9

incomplete combustion

Question 10

What is incomplete combustion?

Answer 10

not enough oxygen to create carbon dioxide

Question 11

Which combustion reaction has only partial oxidation?

Answer 11

Incomplete combustion

Question 12

What does complete combustion create?

Answer 12

Carbon dioxide, and global warming because of trapped heat

Question 13

Complete combustion

Question 14

What does complete combustion produce?

Answer 14

CO and water

Question 15

What does incomplete combustion produce as byproducts?

Answer 15

Carbon monoxide and carbon dust and water

Question 16

Which combustion has air pollutant as an impact?

Answer 16

Incomplete combustion

Question 17

What do neutralization reactions contains?

Answer 17

Contain hydrogen ions (acid)

Question 18

What is released in a combustion reaction.

Answer 18

heat and light.

Question 19

What effect can combustion reactions have on the environment?

Answer 19

They can contribute to climate change and produce air pollutants.

Question 20

How are combustion and respiration similar?

Answer 20

Both involve oxidation and produce carbon dioxide and water as byproducts.

Question 21

What is neutralization?

the type, and how it occurs

Answer 21

It is a type of double replacement where an acid and a base react, canceling each other out and creating a neutral solution, typically water and a salt.

Question 22

What is the typical complete combustion reaction?

Answer 22

A hydrocarbon and oxygen react to produce carbon dioxide and water.
