Zn + Cu SO 4 —>
What’s the reaction

Single displacement reaction

Explanation:

You have an element (Zinc)  + a compound that consists of an element (Copper) and a polyatomic ion (Sulfate)  

Since there's one element and one compound, the metals in both trade places, giving us Zinc Sulfate and Copper as our products.

This should be the complete balanced equation:

Zn + CuSO4 > ZnSO4 + Cu

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
