Is concrete a Natural Material or Synthetic Material

4nh3+5o2--> 4no+6h20what is the total number of moles of h2o produced when 12 mole of nh3 is completely consumed?

In an exothermic reaction, energy may be released to the surroundings in the form of question 4 options: heat light thermal all of the above

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?
