Explanation:
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.

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
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.

When a substance melts it is said to go through all of the following except:
A. phase change
B. physical change
C. chemical change
D. temperature change
Answers
Melting is not a chemical change. It is a physical change involving the transition from solid to liquid without altering the chemical composition of the substance. The correct option is C.
Melting is indeed a phase change, as the substance transitions from a solid phase to a liquid phase.
Melting is a physical change because the substance's molecular arrangement changes from the ordered structure of a solid to the less ordered structure of a liquid, but the chemical composition remains the same.
Melting is not a chemical change. In a chemical change, the substance undergoes a transformation at the molecular or atomic level, resulting in the formation of new substances with different chemical properties. Melting involves a change in physical state.
Melting involves a temperature change. The temperature remains constant during the melting process, as the heat energy is used to break the intermolecular forces holding the solid together rather than increasing the temperature of the substance.
Therefore, melting is a physical change involving the transition from solid to liquid without altering the chemical composition of the substance. The correct option is C.

How is mass conserved during photosynthesis?
-The mass of the reactants (carbon dioxide and water) is the same as the mass of the products (oxygen and sugar).
-The mass of the reactants (carbon dioxide and water) is different from the mass of the products (oxygen and sugar).
-The mass of the reactants (carbon dioxide and oxygen) is the same as the mass of the products (water and sugar).
-The mass of the reactant (carbon dioxide) is different from the mass of the products (water, oxygen, and sugar).
HELP PLEASE
Answers
Answer:
-The mass of the reactants (carbon dioxide and oxygen) is the same as the mass of the products (water and sugar).
Explanation:
Certified Educator The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed. That means, the total mass for the reactants needs to equal the total mass of the products. The reactants for photosynthesis are 6 carbon dioxide, 6 water and sunlight.
Answer:
Pizza is great
Explanation:
I think this because pizza toppings are also packed with a compound called glutamate, which can be found in the tomatoes, cheese, pepperoni and sausage. When glutamate hits our tongues, it tells our brains to get excited and to crave more of it. This compound actually causes our mouths to water in anticipation of the next bite.

D) The particles in lead are more spread out than those in corn oil.
Explanation:
The higher density an object has, the less spread out the particles in the object is. SInce lead's density is 11.35 and corn oil's density is 0.90, corn oil's particles would be more spread out.
