If the cost of electricity required to discharge 10g of an ion X\(^{3+}\) is N20.00, how much would it cost to discharge 6g of ion Y\(^{2+}\)?
[1 faraday = 96,500C, atomic masses are X = 27, Y = 24]
The cost of discharging 6.0g of a divalent metal, X from its salt is ₦12.00. What is the cost of discharging 9.0g of a trivalent metal, Y from its salt under the same condition?
[X = 63, Y = 27, 1F = 96,500C]
How many alkoxyalkanes can be obtained from the molecular formula C\(_4\)H\(_{10}\)O?
The reaction \(2H_2 S + SO_2 \to 3S + 2H_2 O\) is
A solution X, on mixing with AgNO\(_3\) solution gives a white precipitate soluble in aqueous NH\(_3\), a solution Y, when also added to X, also gives a white precipitate which is soluble when heated solutions X and Y respectively contain
