If 2.50 grams of perchloric acid (MW 100.5 g/mole) are dissolved in enough water to make 12.0 liters of solution, what will be the pH of the solution. Thank you!!!​

Significant figures are digits read directly from the measuring instrument plus one more digit, which is __ by the observer.

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

How is energy related to the change of state represented by the model? atoms gain energy as a solid changes to a liquid. atoms gain energy as a solid changes to a gas. atoms lose energy as a solid changes to a liquid. atoms lose energy as a solid changes to a gas.
