2. Air At 275 K Flows Parallel To A 1m X 1m Flat Plate Which Is Maintained At 425 K. The Free Stream Velocity Of The Air Is 25 M/S. Determine The Heat Transfer Rate (W) From The Turbulent Region Of The Plate.

answer should be 5399 W

 

Q37;

Propose a reaction mechanism for the following: Mg(s)+2HCl(aq)---->H2(aq)+MgCl2(aq)

The reaction order is 4; Rate=k?[HCl]?^2 ?[Mg]?^2

I need help determining the elementary steps as chemical equations
