Colors!!
We know about all the colors in the rain bow but do you know how most of them are made?

Red and blue and yellow can make sooooo many different colors if you mix them together.

For example red + blue = purple! This is because red, blue and yellow are primary colors and these colors are colors that can make up other colors.

Which statements about the reaction are true? Select all that apply. The reaction is exothermic The reaction is endothermic The

Digiron [165]

The statements true for the reaction are A, C, and E.

The potential energy diagram of the following reaction has been given:

$\rm CH_4\;+\;2\;O_2\;\rightarrow\;2\;H_2O\;+\;CO_2\;+\;891\;kJ$

The reaction has been given to form water and carbon dioxide, along with the release of 891 kJ of energy.

<h3>Statements for the reaction</h3>

The endothermic reaction is the type of reaction that absorbed the energy from the system, while exothermic reaction released energy in the system.

The given system has releasing 891 kJ of energy. Thus, it has been an exothermic reaction.

The equation has been representing the 891 kJ of energy as the product. Thus, it has been released in the reaction as product.

The potential energy graph has been representing that the energy of the reactant has been higher than the product.

Thus, the statements true for the reaction are A, C, and E.

Why isn't energy ever truly destroyed?

lakkis [162]

Answer:

In physics, the law of conservation of energy states that the total energy of an isolated system cannot change—it is said to be conserved over time. ... Energy can be neither created nor destroyed, but can change form; for instance, chemical energy can be converted to kinetic energy.
