Answer:
Difference: A chemical property is a property of matter that describes a substance's ability to participate in chemical reactions. A physical property is a characteristic of a substance that does not involve a chemical change.
Similar: Ways they are similar are that they both affect shape, color, and size. Both involve changes in the state of matter and have energy charges.

Which equation represents a fusion reaction?
Answers
Answer:
B
Explanation:
I took the test
The equation that represents a fusion reaction is ²₁H + ²₁H = ⁴₂He and the correct option D.
A fusion reaction is a type of nuclear reaction that involves the merging or combining of two or more atomic nuclei to form a heavier nucleus. This process releases a significant amount of energy.
In fusion reactions, the atomic nuclei overcome the electrostatic repulsion between positively charged protons and come close enough for the strong nuclear force to bind them together. This typically occurs at extremely high temperatures and pressures, such as those found in the core of stars or in experimental fusion reactors.
The most well-known fusion reaction is the fusion of hydrogen isotopes, deuterium and tritium, to form helium. This reaction is the primary process that powers the Sun and other stars, and it is also the focus of research efforts to achieve controlled nuclear fusion for practical energy production on Earth.
Thus, the ideal selection is option D.

As the mass of an object increases, what happens to the gravitational force created by that object?
Answers
Answer:
the gravitational force is proportional to the mass of both interacting objects, bigger objects will attract each other with a greater gravitational force. So the mass of either object increases, the force of gravitational attraction between them also increases.
Answer:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force.So the gravitational attraction between them also increases.

~Read the article excerpt then respond to the question below.~
"Scientists make synthetic substances by arranging atoms and molecules in the lab. They use what they know about different types of atoms and molecules to arrange them and make the kinds of substances they want.
Synthetic medicines aren’t any different at the atomic level from the natural medicines found in the rainforest. After all, molecules are just molecules—whether they’re made in nature or in a lab, the same types of atoms arranged in the same ways always form the same molecules that behave in the same ways."
At the atomic level, are synthetic medicines different from natural medicines?
Explain your thinking.
Answers
Although herbal medicines are less potent in comparison to synthetic drugs in some cases but still these are consider less toxic or having less side effect in contrast to synthetic drugs. The ultimate norm for any medicine (human made or natural) is their non-toxicity, effectiveness, specificity, stability and potency.
