Acid base distinction according to Brönsted?

ByYeeeeeeeeeeet1

I'm having trouble distinguishing between acid and base in a substance. (The full reaction equation clearly indicates which is which.) Without the full reaction equation or prior knowledge of the substance itself, I could never know, for example, that NH4 is incapable of converting to NH5. Therefore, this is precisely my problem (NH4 can convert…

Determine the equilibrium constant for first-order nuclear decay?

ByDark4ThunderLP

The specific task is: "A nuclear decay of 87/38 Sr to 87/39 Y can be described by the first-order reaction. The half-life of the reaction is 27 years. Determine the equilibrium constant." I've never calculated the equilibrium constant K using first-order reaction formulas…only the rate constant k. How do I solve this problem?

An example of an exothermic reaction is the combustion of wood in which heat is released. Another example is the reaction between sodium and chlorine, in which heat is also released.

An example of an endothermic reaction is the evaporation of water in which heat is absorbed from the environment in order to provide the necessary energy for the phase transformation. A further example is the reaction of barium hydroxide octahydrate with ammonium thiocyanate, in which heat is likewise absorbed from the environment.

The evaporation of water is not a chemical reaction.

Exotherm: H2 + 1/2 O2 -> H2O, goes by alone, end condition is energetically preferred
Endotherm: H2O -> H2 + 1/2 O2, energy must be applied, final state energy higher
