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

Why do electrons enter the 4s orbital before entering the 3D orbital

garri49 [273]

The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel. (:

write a balanced chemical equation for each single replacement reaction that takes place in aqueous solution. write no reaction

Illusion [34]

The question is incomplete, here is the complete question:

Write a balanced chemical equation for each single replacement reaction that takes place in aqueous solution. write no reaction if a reaction does not occur

1.) Zn + PbCl₂

2.) Cu + Fe(NO₃)₂

Answer:

For 1: The reaction does occur.

For 2: The reaction does not occur.

Explanation:

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element.

The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.

$A+BC\rightarrow AC+B$

For the given options:

For 1:

Zinc is more reactive than lead as it lies above in the series. So, it will displace lead from its chemical equation.

The chemical equation for the reaction of zinc and lead chloride follows:

$Zn+PbCl_2\rightarrow ZnCl_2+Pb$

For 2:

Copper is less reactive than iron as it lies below in the series. So, it will not displace iron from its chemical equation.

The chemical equation for the reaction of copper and iron (II) nitrate follows:

$Cu+Fe(NO_3)_2\rightarrow \text{No reaction}$

A small cube of iron and a large flat sheet of iron contain the same volume. Which one will completely rust first? Explain why.

Hunter-Best [27]

The flat sheet will completely rust before the iron cube. Since they both have the same volume, the flat sheet has more surface area than the small cube. This means more particles are exposed on the flat sheet that can react in a chemical reaction.

2. The Density of Water is 1.0000g/cm3. Based on this property of water,

Vanyuwa [196]

Answer:

if the object sank then that object has a greater density then water. if the object floated then its density is lower then water.

Explanation:

lets say object 1 has a density of 24/cm3. the density is greater then water (1.0000g/cm3) so it would sink. now lets say object 2 has a density of 0.79383g/cm3 since it's less then the density of water (1.0000g/cm3) it would float.
