What happens when a zinc strip is dipped into a copper sulphate solution?
Write the equation for the reaction that takes place.
What happens when a zinc strip is dipped into a copper sulphate solution?
Name the type of reaction involved.
When a black metal compound XO is heated with a colourless gas Y2, then metal X and another compound Y2O are formed. Metal X is red-brown in colour which does not react with dilute acids at all. Gas Y2 can be prepared by the action of a dilute acid on any active metal. The compound Y2O is a liquid at room temperature which can turn anhydrous copper sulphate blue.
(a) What do you think is metal X?
(b) What could be gas Y2?
(c) What is compound XO?
(d) What is compound Y2O?
(e) Write the chemical equation of the reaction which takes place on heating XO with Y2.
(f) What type of chemical reaction is illustrated in the above equation?
Classify the following reaction as combination, decomposition, displacement, precipitation and neutralization. Also balance the equation.
\[\ce{AgNO3_{(aq)} + NaCl_{(aq)}-> AgCl_{(s)} + NaNO3}\]
Name the type of reaction which is governed by the position of a metal in the metal activity series ?
Explain the terms with examples.
Displacement reaction
Classify the following reaction into different type:
Zn + CuSO4 → ZnSO4 + Cu
Complete the given chemical equation:
\[\ce{Zn(s) + CuSO4(aq) -> \underline{}\underline{}\underline{}\underline{}\underline{} + \underline{}\underline{}\underline{}\underline{}\underline{}}\]
Name the type of reaction.
