Explanation:
The variable that is the independent one is the one that Jasmine is changing. In this case, it is the amount of solar panel covered, via a piece of paper.
Answer:
22.5 mL
Explanation:
We are given an amount of a fluid in a graduated cylinder and required to determine its volume.
Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.
The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL
Oxygen(O)
Explanation:
Oxygen is the most reactive of all the listed elements. One can determine their reactivities based on the electronegativity values.
- Every element combines with one another to attain stability like the noble gases.
- Electronegativity is the relative ease with which the atoms of elements attracts valence electrons in a chemical bond.
- On the pauling's electronegativities table of elements, carbon is 2.5, oxygen 3.5 and Cl is 3.0
- Oxygen will have the highest reactivity and the most tendency to combine with other atoms.

False. It can’t because a glaciers weight combined with its gradual movement can drastically reshape the landscape over hundreds and even thousands of years.
Answer:
The answer to your question is: letter C
Explanation:
The only difference between the samples of Zinc is their presentation, one is a chunk of zinc and the other one is shavings.
1) Catalyst This option is incorrect because the description
do not mention anything about catalyst.
2) Nature of the reaction The nature of the reaction is the same.
3) Surface area This is the right answer because in the chunk
there is less surface area than in the shavings.
4) Temperature It is not mention anything about temperature in
the description.
