Without the law of definite composition, formation of a compound cannot be truly explained. What is your view on this topic? Are there any other factors that should be considered?
Calculate the final temperature of the solution assuming no heat is lost to the surroundings, the final mixture has a mass of 100.0 g and the solution has a specific heat capacity of 4.18 J °C-1 g-1
Assume that the electrode follows the Nernst equation, the temperature is at 25°C, and that the activity coefficient of X is 1.
what is your prediction for the next reaction?
A hot air balloon is inflated to its full extent by heating the air inside it. In the final stages of this process the volume of the balloon changes from 4.00 x 10^6 L to 4.50 x 10^6 L by addition of 1.3 x 10^8 J of energy as heat.
