Why do we burn fuel?

A

To release energy

32
Q

What type of reaction is burning fuel?

A

Chemical

33
Q

There are different types of chemical reaction, what type is burning fuel?

A

Combustion reaction

34
Q

How can a chemical reaction be written as a word equation with an arrow representing the chemical change occurring?

A

Reactant ———> Products

35
Q

What is the word equation for combustion?

A

Fuel + oxygen —-> carbon dioxide + water

36
Q

Testing for the products of combustion How do you test for carbon dioxide and what would you see?

A

Bubble water through limewater and the clear colourless solution goes cloudy

37
Q

Testing for the products of combustion Water

A

Use cobalt chloride paper and, if water is present, the paper will turn from blue to pink

38
Q

What do we call a reaction that gives off heat?

A

Exothermic

39
Q

What do we call a reaction that takes in heat?

A

Endothermic

40
Q

What is an exothermic reaction?

A

a reaction that gives out heat, the surroundings heat up

41
Q

What is an endothermic reaction?

A

a reaction that takes in heat, the surroundings get colder

42
Q

The characteristics of living things What are the characteristics of MRS GREEN

A

Movement - organism can change position Respiration - organism releases energy from a food source, requires oxygen Sensitivity - organism responds to things Growth - organism gets bigger Reproduction - organism makes copies of themselves Excretion - organism gets rid of waste material Nutrition - organism consumes chemical material for food

43
Q

The characteristics of living things For MRS GREEN what do we mean by: Movement

A

The organism can change its position

44
Q

The characteristics of living things For MRS GREEN what do we mean by: Respiration

A

49
Q

The characteristics of living things For MRS GREEN what do we mean by: Nutrition

A

The organism consumes chemical material as food

50
Q

How do we remember the characteristics of living things: Movement, respiration, sensitivity, growth, reproduction, excretion and nutrition?

A

MRS GREEN

51
Q

What is a dichotomous key?

A

A qtype of single- access key that offers only two choices at one time such as Backbone or no backbone Wings or no wings She’ll or no she’ll

52
Q

What do we call a type of single- access key that offers only two choices at one time such as Backbone or no backbone Wings or no wings She’ll or no she’ll

A

Dichotomous key

53
Q

Which is easy and which is hard to reverse, usually? Chemical change Physical change

A

Chemical change is hard to reverse as the reactants produce new substances, the products Physical change is easier to reverse as it affects the form - solid, liquid or gas
