A chemical element is a pure substance that consists entirely of one type of atom. Atoms of any element should have same number of protons but they can have different number of neutrons.  

Elements are the simplest substances that can not be broken down by using the chemical reactions these can be changed into other elements using nuclear methods.

How many moles are in 5.0 x 10^25 atoms of iron?
Andreas93 [3]

Hello!

To find the number of moles that are in the given amount, we need to divide the total number of atoms by Avogadro's number, which is 1 mole is equal to 6.02 x 10^23 atoms.

5.0 x 10^25 / 6.02 x 10^23 ≈ 83.0564

Therefore, there are about 83.06 moles of iron (sigfig: 83 moles).

Which reverses the flow of current through an electric motor?
kirill [66]

Answer:

D

Commutator is the answer

Explanation:

The commutator systematically converts the current direction between the rotor and the outer circuit. As the shaft revolves, the commutator converts the course of current in a winding. For a separate armature winding, when a cylinder has reached one-half perfect turn, the winding is now attached so that current passes through it in the reverse of the original direction.

What of these should Hailey include in her list?
Natalka [10]

Answer:

Hailey should add, they are inexpensive to produce.

Explanation:

Reason being why they are inexpensive to produce, is due to them being chemical based and easy to product in the factory setting. Which makes them extremely cheap to make.

Reason being why the others are wrong, synthetic polymers are <u>not</u> biodegradable as they are made in a factory with oils. Synthetic polymers are <u>not</u> flexible due to them being used for harder products. Synthetic polymers are <u>not</u> recycled cheaply as they are made with chemicals which makes it very hard to recycle.
