Frequently asked questions
What is Topic C4: Predicting and identifying reactions and products?
Topic C4: Predicting and identifying reactions and products covers Predicting chemical reactions in GCSE OCR Higher Combined Science Chemistry. 14 lessons in 1 subtopic.
What is the order of the metal reactivity series?
The metal reactivity series, from most reactive to least reactive, is potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, copper. The Metal Reactions and the Reactivity Series notes cover this in full.
What are the noble gases?
The noble gases are the Group 0 elements helium, neon, argon, krypton, xenon and radon. The Trends in Noble Gas Properties notes cover this in full.
What is a displacement reaction?
A displacement reaction is a reaction where a more reactive element takes the place of a less reactive element in a compound. The Displacement Reactions and the Extended Reactivity Series notes cover this in full.
What is a redox reaction?
A redox reaction is one in which oxidation and reduction both occur. The Understanding Oxidation and Reduction with Electrons notes cover this in full.
What are halogens?
Halogens are the elements in Group 7 of the periodic table, including fluorine, chlorine, bromine, iodine and astatine. The Introduction to Group 7 Halogens notes cover this in full.
What happens when a metal reacts with an acid?
A metal reacting with a dilute acid produces a salt and hydrogen gas: metal + acid → salt + hydrogen. The Metal Reactions and the Reactivity Series notes cover this in full.
What are the properties of alkali metals?
Alkali metals are soft enough to cut with a knife, have low melting points compared to other metals and have low density; lithium, sodium and potassium float on water. The Introduction to Group 1 Elements - The Alkali Metals notes cover this in full.
Why are noble gases unreactive?
Noble gases are unreactive because their atoms have stable arrangements of electrons with complete outer shells, so they do not need to gain, lose or share electrons. The Noble Gases: Structure and Unreactivity notes cover this in full.
