Why science can answer some questions, but not others

By what factor does [h+] change for a ph change of 2.39 units.

What would happen to the rate of a reaction with rate law rate = k no2 h2 if the concentration of h2 were halved?

A backpacker wants to carry enough fuel to heat 2.2 kg of water from 28 ∘C to 100.0 ∘C. If the fuel he carries produces 36 kJ of heat per gram when it burns, how much fuel should he carry?

Is this true or false? A decomposition reaction is the opposite of a synthesis reaction?

What is the role of the activated complex in a chemical reaction?

In a calorimetry experiment, it was determined that a 92.0 gram piece of copper metal released 1860 J of heat to the surrounding water in the calorimeter (qcopper = - 1860 J). If the final temperature of the copper metal-water mixture was 25.

If i walk 25 steps north than 75 steps south, what is my final position

At a different temperature (this means that Keq will be different than part a)), 6.0 mol of IF5 and 8.0 mol of I4F2 are placed in a 10.0 L container. At equilibrium, 6.0mol of I4F2 are left. Calculate the Keq for the new temperature.
