If the potential energy of the product is less than that of the reactants, the energy released when an activated complex forms a product will be more than the activation energy resulting in an exothermic reaction.1.True2.False

True

Explanation:

In a chemical reaction, if the reactants have more potential energy than the products have, the extra energy is released to the surroundings as heat. This type of reaction is exothermic.

The activation energy is the difference between the energy of the reactants and the maximum energy (the activated complex).

The activated complex is the complex that exists as the bonds in the products are forming and the bonds in the reactants are breaking. This Complex exists when the energy of the system is at its maximum.

The correct option is;

1. True

Explanation:

Here, we note that an activated complex is the intermediate form of the reactants during the conversion of the reactants into a product with a structure representing the point with maximum energy along the path of the reaction. As such here the complex forms a product the released energy will be more than the activation energy resulting in the exothermic reaction.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
