25
Q

What is a Thermite reaction used for?

A

Welding Railway Tracks

26
Q

What does diatomic mean?

A

diatomic means two atoms- hydrogen is H2(little 2) and oxygen is O2(little two) because they naturally have two atoms in tjem

27
Q

Exothermic- meaning and what will happen

A

Exo- gives out thermic- heat, gives out energy so it will be hot

28
Q

Endothermic- meaning and what will happen

A

Endo- takes in thermic- heat, takes in energy so will be cold

29
Q

what is a base? [2]

A

A Metal Oxide and it makes an alkali

30
Q

what is a limiting reaction?

A

where the reactant used get used up in the first reaction
