Fiesta28 [93]3 years ago
6 0

Answer:

Four types of molecules important for cell processes:

1. Proteins

2. Carbohydrates

3. Lipids

4. Nucleic Acids

Explanation:

Foremost, Molecules are groups of atoms that bonded and held together by chemical bonds - which form compounds. Cell processes all involve the interaction of molecules and atoms alike. These four groups are absolutely essential for every single organism on Earth. A cell and organism would not be able to live without these vital molecules.

I hope this helps!

Answer:

four types of molecules important for cell processes include carbohydrate, protein, lipid and nucleic acid

Explanation:

Molecules are made up of atom which react together to form a chemical compound, the above named molecules forms the basis of every cells as they vital roles in cells functions, hence; they are the building block of the cell

Polyatomic ions: CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-

Monatomic ions: Ca^{2+, O^{2-, and Fe^{3+

<h3>Monoatomic vs Polyatomic Ions</h3>

In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include  Ca^{2+, O^{2-, and Fe^{3+

Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.

Examples of polyatomic ions are  CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-

Thus, from the diagram:

  • Polyatomic ions: CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-
  • Monatomic ions: Ca^{2+, O^{2-, and Fe^{3+

Describe the properties of alkali metals. Based on their electronic arrangement, explain whether they exist alone in nature.
bearhunter [10]

Answer:

- They are highly reactive metals

- They have low electro negativity

- They have low ionization energy

- They don't exist alone in nature

- They have low densities

Explanation:

Alkali metals are the elements in group 1 of the periodic table. They include Sodium, Lithium, Potassium e.t.c.

Due to the fact they have one atom in their outermost shell, they are very unstable because they easily react with other elements and are therefore don't exist alone in nature but combined with other elements for this same reason.

Since alkali metals don't easily attract other elements due to it's lone pair in the outer most shell, it can be said to have low electro negativity.

Also, they don't need energy to discharge their electrons since they are highly reactive due to their lone pair in the outermost shell and so we say they have low ionization energy.

Due to this reason, they also have low densities.

Chemists use activity series to determine whether which type of reaction will occur?

Single replacement reactions.  For example copper is more reactive than silver.  So a copper wire in a silver solution will cause the silver to become a metal again.

Relative to the mass of the nucleous of a atom. the mass of electron is​
Paladinen [302]
The number of protons found in the nucleus equals the number of electrons that surround it, giving the atom a neutral charge (neutrons have zero charge). Most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen.Hoped this helped

Please answer fast!!! what does base stand for in science
pychu [463]
There are multiple meanings for a base. A base can be a substance that accepts hydrogen ions, or it could be something that is not acidic, in other words meaning its pH is between 7 and 14.
