In the Tough Man Competition, very strong men are challenged to push or pull extremely large and heavy objects to test their str

ength. In one such challenge, they were asked to push one of two rail cars, an engine car and a box car. The data tables show one man’s results. Look over the data table and answer the questions below.
A. Why couldn't the strong man move the box car with a force of 3000 Newtons? Make sure to include Newton's 2nd Law in your explanation.

B. What could be done to move the boxcar?

C. Another student claims that during the competition, the sum of the forces on the boxcar was 0 N. What evidence is the student using to make this claim? Be sure to explain your thinking.

Is it possible to turn one metallic element into a different metallic element in a chemical reaction? Explain.
lord [1]
No, it is impossible.

Chemical reactions does not change or turn elements into different elements.

Changing an element implies to modify its atomic number (the number of protons in the nucleus).

Chemical reactions do not modifiy the nuclei of the elements involved.

Chemical reactions imply the formation or rupture of bonds between elements. Bonds are union of elements at the level of electrons.So, formation or rupture of bonds involve only a different combination of the atoms, never modifications of the atoms at the level of nuclei or parts of nuclei.

What is the classification for this reaction? so3 (g) + h2o (l) → h2so4 (aq)?
ryzh [129]
There are six common types of reactions:

1. Combination
2. Decomposition
3. Single Displacement
4. Double Displacement
5. Combustion
6. Redox

The reaction: SO₃₍g₎ + H₂O₍l₎ → H₂SO₄₍aq₎ is classified as a combination reaction. This is because for combination reactions, two (or more) reactants form a single product. On the other hand, decomposition reactions involve a single reactant breaking down into two or more simpler substances. Displacement reactions involve a more active element displacing a less active element from a compound. Meanwhile, combustion reactions involve a carbon-containing compound reacting with oxygen to form carbon dioxide and water. Redox reactions then involve exchange of electrons between species.

PLEASE HELP ASAP. 44 minutes left! Extra points and BRAINLIEST!!
Vanyuwa [196]

Answer:

Explanation:

Artificial or induced transmutation occurs when atoms of one element are struck with particles in a linear accelerator, cyclotron, or synchrotron. ... With this process, some of the protons from the bombarding particles are lodged in the target nucleus, promoting the transmutation into a different element.

What elements react the most? Like have the most reactivity.
Vera_Pavlovna [14]

If you mean what group of elements react the most, the answer is the alkali metals and the halogens because they both only either need to gain or lose one electron. If you mean the most reactive element, it would be fluorine because it has the most electronegativity.
