Explanation:

During a chemical change, a new kind of matter is formed. Examples are combustion, rusting of iron, precipitation and souring of milk.

Here are some of the properties of chemical change:

  • They are not easily reversible
  • It leads to the production of new kinds of matter.
  • It involves change in mass.
  • It requires a considerable amount of energy.

Answer:

The options are missing in the question, so I am going to answer it in a general way.

There are several indicators of chemical reactions. They are:

  • Gas Bubbles Appear
  • Formation of a Precipitate
  • Color Change
  • Temperature Change
  • Production of Light
  • Volume Change
  • Change in Smell or Taste

Depending of what kind of reaction is occurring which indicator appear. For example in combustion reactions the temperature increase because they are highly exothermic; and in electrolysis of water, bubbles of molecular oxygen and molecular hydrogen are generated.

A hydrogen-like ion is an ion containing only one electron. The energy of the electron in a hydrogen-like ion is given by:
kupik [55]

hydrogen-like ion is an ion containing only one electron. The energy of the electron in a hydrogen-like ion is given by:

En = −(2.18 × 10^−18J) Z^2 ( 1/n^2 )

where n is the principal quantum number and Z is the atomic number of the element. Plasma is a state of matter consisting of positive gaseous ions and electrons. In the plasma state, a mercury atom could be stripped of its 80 electrons and therefore could exist as Hg80+. Use the equation above to calculate the energy required for the last ionization step.hydrogen-like ion is an ion containing only one electron.

The graph shows the reaction pathway for the reaction Q + R N + M. Interpret the graph by describing what each of the letters (A
Vladimir [108]

Answer: The reaction is exothermic reaction as the energy of products is less than the energy of reactants.

Explanation: Exothermic reactions are defined as the reactions in which energy of the product is less than the energy of the reactants. The total energy is released in the form of heat and \Delta H for the reaction comes out to be negative.

Labeling of the parts in the diagram:

A represents the activation energy which is the energy required by reactants to cross the energy barrier to get converted to products.

E represents the potential energy of the reactants.

B represents the activated complex.

D represents the potential energy of the products.

C represents the total enthalpy change of the reaction, which comes out to be negative for exothermic reactions.

\Delta H=E_P-E_R
