What you have to do is balance the chemical equations to make sure everything is even on both sides. If you want me to help you answer the questions comment back

What does the part of the equation to the left of the arrow represent in a chemical formula

Hunter-Best [27]

In a chemical formula, the part to the left of the arrow represents the reactants. The reactants are all the chemical elements that will react with each others to make the products (which will be on the right part of the arrow).

Example:
H2 + O2 --> H2O

H2 and O2 are the reactants (on the left part of the arrow) and H2O is the product (on the right side of the arrow)

Hope this helps! :)

For the energy diagram of the chemical reaction depicted here, which statement is the best conclusion?

34kurt

The reaction shown here is an exothermic reaction.

<h3>What is an exothermic reaction?</h3>

An exothermic reaction is one in which the energy of the reactants is greater than the energy of the products. This implies that energy is given out in the process. Whether a reaction is endothermic or exothermic shows in the nature of the reaction profile curve.

For an endothermic reaction, the part of the diagram that represents the energy of the products is higher than the part that represents the energy of the reactants. This is clear from the image attached here.

If we look at the reaction graph very well, we will observe that the energy of the reactants is far above that of the products. Thus it follows that the reaction shown here is an exothermic reaction.
