Third option is the correct one. When an element is oxidized, it loses electrons. This is the basis of redox reactions. However, an oxidizing agent oxidizes something else, and gets reduced, therefore gaining electrons.Endothermic describes a chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature. (adjective). What statement correctly describes the energy of the chemical bonds of the reactants in an exothermic reaction?There are a number of signs that a chemical reaction is taking place. The big thing is that the atoms in a chemical reaction are rearrange and we end up...Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different Chemical reactions must be distinguished from physical changes.

Answer: statement B describes the chemical reaction.21 Which statement correctly describes an endothermic chemical reaction? 27 Chemical Equilibrium The forward and reverse reactions take place at the same rate. 28 Factors Affecting Equilibrium: Le Chatelier's Principle If a stress is applied to a system at equilibrium, the system shifts...Given the reaction system in a closed container at equilibrium and at a temperature of 298 K: N2O4(g) ⇌2 NO2(g) The measureable quantities of the gases at equilibrium must be 4. Which statement about a system at equilibrium is true? You've reached the end of your free preview. Want to read both pages?A chemical reaction takes place when bonds between atoms of the reactants break and new bonds form in the product. An endothermic chemical reaction requires energy to break the bonds and an exothermic reaction releases energy. Reactants go into a reaction and products come out.This will speed up the chemical reaction and explains the mechanism of a catalyst quite nicely. Thus able to react with each faster faster and that being said, catalyst cam speed up a chemical reaction.

The answer is two, on the other hand, consider

If you take away product, the reaction shifts to the right to restore equilibrium so that the Keq, as determined by merchandise x prod divided through reactants x reactants (put in superscripts as suitable) is restored.

An instance: SO2 in water > H2S03 reversible.If SO2 escapes, the concentration of H2SO3 is going down as a result of some dissociates to restore the equilibrium however only enough to handle Keq. Then concentrations are constant again.
