Chemistry

Question 1

Acids

Answer 1

Has a ph of less that 7

Question 2

Bases

Answer 2

Ph greater that 7

Question 3

Ph indicator

Answer 3

A compound that changes colour based on the acidity in a soloution

Question 4

Acid/metal reaction

Answer 4

Salt and hydrogen are produced

Question 5

Oxidation reactions

Answer 5

reactions that involve the transfer of electrons from one species to another

Question 6

Corrosion of metals

Answer 6

occurs when most or all of the atoms on the same metal surface are oxidized, damaging the entire surface

Question 7

Exothermic/Endothermic reactions

Answer 7

Exothermic reactions release energy in the form of light or heat, while endothermic reactions absorb heat energy from their surroundings

Question 8

Combustion reactions

Answer 8

chemical reaction in which a fuel undergoes oxidation by reacting with an oxidising agent, resulting in the release of energy

Question 9

Combustion of fuels and hydrocarbons

Answer 9

chemical reaction that occurs when a hydrocarbon fuel reacts with oxygen in the air, producing water and carbon dioxide

Question 10

Metabolic reactions (Catabolic and Anabolic processes

Answer 10

Metabolism is the sum of all chemical reactions in a cell, and the two main types of metabolic reactions are anabolic -constructive metabolism, anabolic reactions build larger molecules from smaller ones. Anabolic reactions require energy catabolic-destructive metabolism, catabolic reactions break down larger molecules into smaller ones. Catabolic reactions release energy

Question 11

Respiration/Photosynthesis as a metabolic reaction

Answer 11

Photosynthesis and cellular respiration are metabolic reactions that work together to provide energy to organisms
