Answer:
The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".
Explanation:
A chemical change is one which is not easily reversible and which results in the formation of new subsatances.
For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.
From explanations provided by the students :
Luke does not give any explanation of the process but only an observation
Jackie's explanation does not state the main reason why a chemical change differs from a physical one.
Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.
Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.
I'm not sure but I think it's B
Answer:
hii there
how are you?
here's your answer
Explanation:
1 )
The five steps of the scientific method
Step 1: Ask a question or identify a problem. A scientist learns about the universe by observing
Step 2: Background research.
Step 3: Form a hypothesis.
Step 4: Experiment and observe.
Step 5: Draw a conclusion.
2 ) Matter is the stuff that makes up the universe everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Both atoms and molecules are held together by a form of potential energy called chemical energy.
3 ) Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the state of matter. The three fundamental phases of matter are solid, liquid, and gas.
