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 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.
Answer:
<em>A pure substance made up of two or more elements that are chemically combined is a compound</em>
Explanation:
Answer:
If a solid is added to a liquid until no more of the solid will dissolve saturated solution is formed.
Carbon Dioxide environmental gas so as to make carbonic corrosive that is consolidated with water. Carbon dioxide noticeable all around can disintegrate in rain water to frame carbonic corrosive, H2CO3. Carbonic corrosive is a powerless corrosive. It somewhat ionizes to frame hydrogen particles. The hydrogen particles from carbonic corrosive give common rain water a somewhat corrosive pH estimation of 5.6.
Answer: thermochromism, too hot of temperature or long exposure to high temperature may completely degrade the color of an object. In other instances, an object or sample changes to another shade of color until it stabilizes back to room temperature.
