On the periodic table it is the number on the bottom of the element. 
<span>If you know the amount of neutrons you can add it to the number of protons to find the atomic mass NUMBER, which is a good approximate of the atomic mass. </span>

A student pushes on a crate with a force of 100N directed to the right. What force does the crate exert on the student?
Kamila [148]
Hello!

The force on the student is equal to the force the student exerts, so 100N is your answer. 

Hope this helped :))

1) Which term describes the conversion of substances into different substances?(1 point)
lara [203]

A chemical reaction occurs when substances change. Photosynthesis is the process by which plants produce food.

1) A chemical reaction is a process by which substances can be changed into other substances. Hence, in a chemical reaction, new substances are formed.

2) Photosynthesis is the process by which plants produce food using carbon dioxide and water in the process of sunlight and chlorophyll. Glucose is produced during photosynthesis and the energy produced and stored as starch.

3) Valence electrons show the kind of bond that an atom can form. Reaction between two atoms that have many valence electrons is most likely covalent. An ionic bond is formed between an atom that has few valence electrons and an atom that has many valence electrons.

4) A carbohydrate is a compound that comprises of hydrogen and oxygen in a ratio of 2:1. The compound that is a carbohydrate is C3H6O3.

5) Rocks contain iron. Iron oxides form when cyanobacteria produce oxygen via photosynthesis.

What are the correct answers to these questions?
Anni [7]
The answer to both is D. Here's why:
For the first, whenever motion changes in a magnetic field, it causes electrons to move. Electricity, which is needed to power a lightbulb, is just a term for movement of these electrons. Electrons aren't created, they're always there in the wire. It's just that the permanent magnet gets them to move, which produces electricity.
For the second, it is very similar to the first. A magnet won't cause any electric current at rest, it always requires motion in order to produce an electric current. If you keep both of those in mind, it should help in the future. Hope this helps!
