When a chemical reaction occurs, what happens to the atoms of the two substances? Provide an example from the Sim (on Amplify) as evidence to support your answer.

When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.

Answer 1
When a chemical reaction occurs, the atoms of the two substances are rearranged to form new compounds. During the reaction, the bonds between the atoms are broken and new bonds are formed, resulting in the formation of new substances with different chemical properties than the original substances.

An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.
Answer 2

Answer:

Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.

(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.

(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.

(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.

(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.

What would be a good scientific reason to explain why plants that receive more light have more growth?

Light is required for plants to absorb water

Only water influences plant growth

The radiation emitted from the light increases the moisture in the soil

Plants need light for the process of photosynthesis. Without photosynthesis, plants cannot make their own food.

Answers

Plants need light for the process of photosynthesis which is a vital process for their growth and survival. During photosynthesis plants use light energy to convert carbon dioxide and water into glucose and oxygen.
