how do atoms combine to form extended structure?

Answers

Answer:

lose or share electrons in such a way that the outer shells become chemically complete

Explanation:

Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.

When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.

A sturdy plant is placed in an airtight, transparent container. The entire experiment is then weighed. For 10 days, the plant grows inside the container. After 10 days, the container is weighed again. The air inside the container is pumped out and carefully analyzed.

What is true about the air inside the container and the mass of the experiment?

-The air is richer in carbon dioxide. The mass of the experiment has not changed.

-The air is richer in oxygen. The mass of the experiment has changed.

-The air is richer in carbon dioxide. The mass of the experiment has changed.

-The air is richer in oxygen. The mass of the experiment has not changed.

PLEASE HELPPPPP

Answers

i believe it is B the air is richer

Plants release oxygen by photosynthesis and consume carbon dioxide for it. Thus the air after the experiment will be rich in oxygen but the mass of the container dose not change.

What is photosynthesis?

Photosynthesis is a biochemical process by which green plants produce glucose and oxygen with the aid of light energy. Combination of water and carbon dioxide results in the formation of glucose and molecular oxygen.

By photosynthetic reaction, the air will be rich in oxygen and some fraction of carbon dioxide in the atmosphere will be consumed by plants. That's why this process is said to be an event in carbon cycle.

The mass of the container in the experiment does not change, whereas, the air collected will contain more oxygen than before which is released by the plants.
