What is the pH of a 0.30 M solution of (CH3)2NH which is also 0.90 M in (Ch3)2NH2Cl? Note: Kb = 5.4 x 10^-4 for (CH3)2NH

What type of solution is this?

Write the chemical reaction involved and the relevant Ka or Kb expression

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
