During the displacement reaction a student observe that the metal P can displace Q from its salt solution. But Q cannot displace R from its salt solution. Based on the above observation a) Name the most reactive metal. b) Name the salt formed when P displace Cu from CuSO 4 solution.

See the answer below

Explanation:

P can displace Q from its salt solution means that P is more reactive than Q.

Q cannot displace R from its salt solutions means that R is more reactive than Q.

a) There is no information as to which of P and R has the capacity to displace one another from their salt solutions. Hence, the most reactive metal can be either of P and R.

b) When P displaces Cu from CuSO4 solution, the equation can be represented below (assuming that P is monoatomic):

Hence, the product formed is

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
