The difference between the monomer and a polymer should be that monomer should be larger than a polymer.
Difference of monomer and a polymer?The monomer represent the molecule type where it has the capability for chemically the bond along with the other molecules with respect to the long chain. While the polymer should represent the chain of the non-specified the no of monomers.
Also, it represent the building blocks of polymers that contain more complex type of molecules

Does anyone know how to determine if a reaction is a redox or not?
2Ca+O2→2CaO2 is the reaction. I've already made it a balanced equation, I just need to determine if its a redox or not.
Thank you!
The reaction is included in a redox reaction
Further explanation:
Given
Reaction
2 Ca + O₂ → 2 CaO
Required
a redox reaction
Solution
Redox reactions are reactions where there is a change in oxidation number
Oxidation is an increase/increase in oxidation number, while reduction is a decrease/decrease in oxidation number.
Reducing agents are substances that experience oxidation and oxidizing agent are substances that experience reduction
in the above reaction is included in a redox reaction because there is a change in oxidation number
Ca⇒Ca²⁺+ 2e⁻(for balanced equation : 2Ca⇒2Ca²⁺+4e⁻)
Oxidation ( 0 to +2)
O₂+2e⁻⇒O²⁻(for balanced equation : O₂+4e⁻⇒2O²⁻)
Reduction (0 to -2)

Some consumers, like lions, do not eat plants or any other producers. They only eat other animals.
How do lions obtain the carbon they need?
by eating animals that have carbon-based molecules stored in their bodies
by breathing it in from the atmosphere in the form of carbon dioxide
by absorbing carbon-based molecules through their skin from the soil
by drinking water that contains carbon dioxide
Answer:
a
Explanation:
Some consumers, like lions, do not eat plants or any other producers. They only eat other animals. lions obtain the carbon they need by eating animals that have carbon-based molecules stored in their bodies and the correct option is option 1.
What are Consumers?Heterotrophs are known as consumers because they consume producers or other consumers. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.
Heterotrophic living organisms include all animals and fungi, some protists and bacteria, many types of parasitic plants.
Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The systematic distribution of electrons in the various atomic orbitals is called its electronic configuration. The atomic number of vanadium is 23. The electronic configuration of vanadium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d³. The noble gas electronic configuration of vanadium is [Ar]3d³4s². 1,2,3 represents the number of shells and s and represents the orbitals. The superscripts represents the number of electrons in each orbitals.

of 40?
a. 58
c. 22
b. 18
d. 40
Answer:
18
Explanation:
In neutral atom protons and electrons are equal in number as it atomic number or proton number is 18 so electrons are also 18
The total number of electrons in an atom of an element with an atomic number of 18 and a mass number of 40 is 18.
What are the difference between atomic number and atomic mass ?Atomic mass can be defined as the total number of neutrons and protons located in nucleus of an element while atomic number is the number of protons present in the nucleus of element.
Atomic mass can be defined as the average weight of an element where as the atomic number is the total number of protons present in the nucleus; Atomic mass have the symbol A while atomic number have the symbol the letter Z.
Different isotopes of an element are differentiated by atomic mass is while isotopes share the same atomic number, in neutral atom protons and electrons are equal to atomic number or proton number is 18 and electrons are also 18

Provide your answer in the following format: [element name], [chemical family]
Answer: Bismuth (Bi) , Nitrogen family
Explanation:
As the element has 5 valence electrons in the sixth energy level, which mens it belongs to 6th period as the valence electron has entered the 6th energy level.
Now as the electrons are filled according to afbau's rule , the electronic configuration of the element will be :
[tex][Xe]4f^{14}5d^{10}6s^26p^3[/tex]
Now as the atomic number of element is equal to the number of electrons in a neutral atom , the atomic number is 83 and the element is Bismuth (Bi). As the last electron enters p -subshell , it is a p block element. It lies in group 15 which is nitrogen family.
