What is the balanced equation for potassium oxide plus water yields potassium hydroxide?
in practice ,i found that :aluminum powder(pure metal)+potasa (solution)..=potasium aluminate+high amount of heat liberated +wet hydrogen (mixed with water vapor) PROJECT STUDY : How to manipulate this equation to make use of the products gained ? 1-) Hydrogen (drying plant) 2-)potasium aluminate (uses in several branches in industry ) 3-)precise control of the heat liberated (measuring the amount of heat) 4-) a very smart and precise control system of the entire plant (elements of control system i.e solenoid valves..selection of the construction metal of the chemical reactor..safety relief valves..reaction time..automation of system which deals with the residual...microprocessing control of the system 5-)How to make use of the enthalpy liberated to generate electricity ? PLEASE : THIS IS CONFIDENTIAL AND I NEED HELP FROM PROFESSORS TO WORK AS ONE GROUP..

The temperature of a piece of unknown metal with a mass of 18.0 g increases from 25.0 degrees C to 40 degrees C when the metal absorbs 124.2 J of heat What is the specific heat of the unknown metal?
Without stating units, it is impossible to answer this question accurately. However, the equation you would need is q=mc∆T, where q is the heat flow (the 53.0 listed, likely Joules), m is the mass of the unknown metal (11.1, likely grams), c is the specific heat of the metal (the unknown you need to solve for), and ∆T is the change in temperature of the metal (24.1-13.0, likely Celcius). Rearranged to solve for specific heat, the question is c=q/m∆T.
