When food inside the pressure cooker boils, steam is produced. Using the particle theory of matter, please explain (i) why the food inside the pressure cooker can be cooked at a very high pressure.
And (ii) state two advantages of using the pressure cooker to cook food.
What volume in mL is needed for the solution of HCl to react with a sample of Al 16.0? 2Al +6HCl => 2Al + 3H2. Calculate the molar concentration of ions in a 0.0200M solution is in Al(NO3)3
