Answer:

A. The siding on a house buckles on a hot day

Explanation:

The key word in this question is EXPANSION. Without even knowing the siding expands causing it to buckle when it's hot, you can use process of elimination. It can't be answer B because watered down iced tea would most likely be as a result of the ice melting which is the opposite of expanding. It can't be C because air is not solidified and therefore can't expand. Lastly, D cannot be it because ice cream expands when cold, causing it to become hard. If it's not hardening then it's not expanding. This is also the correct answer on a p e.x

She remembered that chemical equations can summarize what happens in a chemical reaction. What is the name of the two parts found on the left side of the equation below? 4 Fe + 3O2 → 2Fe2O3 A. products B. reactants C. scientific notation D. synthesis

Answers

Answer:

The name of the two parts found on the left side of the equation is reactants.

Explanation:

Chemical reaction is the way one substance reacts against another. That is, a chemical reaction is that chemical process in which two or more substances, by the action of an energy factor, are converted into other substances. The new substance (s) that are formed usually present a totally different appearance from that of the starting substances.

In a chemical reaction there are the substances that react, that is, the reactants, and the substances produced, called products.

A chemical reaction is represented by a chemical equation. The formulas of the reactants are written on the left, and those of the products on the right, both separated by an arrow indicating the direction of the reaction.

Reactants ⇒ Products

Then, the name of the two parts found on the left side of the equation is reactants.
