lana66690 [7]

Answer:

2. B.

Explanation:

  • The letter B represents the activated complex.
  • The activated complex is the intermediate that is formed between the states of reactants "F" and products "G".

  • Letter A represents the activation energy of the reaction, that is the difference in potential energy between the reactants "F" and activated complex "B".

  • Letter C represents the enthalpy change of the reaction, that is the difference in potential energy between products "G" and reactants "F".

  • Letter D represents the potential energy of products "G".

  • Letter E represents the potential energy of reactants "E".

Justin mixed two clear liquids together during an experiment and made the following observations:
svp [43]

Answer:

B. A chemical change occurred which caused the liquid's physical properties to change.

Explanation:

The reduction of the temperature of the system meant that the reaction absorbed heat energy from it. This shows that a chemical reaction was in progress. New products were formed, and this is proved by the change in the color to blue.

Given the reaction: 4NH3 + 502 4NO + 6H2O
Ainat [17]

Answer:

\frac{4}{5} moles

Explanation:

The reaction equation is given as:

      4NH₃   +  5O₂  →  4NO  +  6H₂O

The number of moles of O₂ that completely reacted is given as 1 mole

To solve this problem, we are going to use a stoichiometric approach from the balanced reaction equation:

         5 moles of O₂ will react completely to produce 4 moles of NO

        1 mole of O₂ will therefore react to produce  x mole of NO

               5x  = 4

                 x  = \frac{4}{5} moles of NO
