What is predicting a metal displacement reaction?Show answer
A metal displacement reaction is one where a metal in elemental form reduces the cation of a less reactive metal, taking its place in solution:
What is reaction with water?Show answer
The most reactive metals (group 1 and the more reactive group 2) react directly with cold water to produce hydrogen gas and a metal hydroxide:
What is reaction with dilute acid?Show answer
Any metal above hydrogen in the activity series reacts with a dilute acid (such as or dilute ) to give hydrogen gas and a soluble salt:
What is reaction with oxygen?Show answer
All but the noble metals react with oxygen, though the rate and the temperature required differ enormously.
What is q1?Show answer
A nail is placed in solution. State the observation and write the net ionic equation. [3 marks]
What is q2?Show answer
of magnesium is added to excess silver nitrate solution. (a) Write the net ionic equation. (b) Calculate the mass of silver deposited.
What is q3?Show answer
Consider zinc, copper and silver. (a) Rank by reactivity. (b) Predict whether will react with and write the equation if it does.
