Lipids is the class of macromolecule was described as being most like the hydrocarbons.

Macromolecules are bigger molecules of large size and made of smaller molecules called as monomers, Polymers are macromolecules.

All Macromolecules are not like the hydrocarbon because the macromolecules not only consists of  C and H atoms but also N and O.

Macromolecules are classified into 4 types

Proteins , Carbohydrates , Lipids and Nucleic Acids

Lipids is the class of macromolecule was described as being most like the hydrocarbons.

Lipids are a broad category of chemicals that are mostly nonpolar in nature.

This is due to the fact that they are hydrocarbons with nonpolar carbon–carbon or carbon–hydrogen bonds.

The IUPAC name for NH3 is Ammonia  

The IUPAC name is also known as (International Union of Pure and Applied Chemistry) and it is a standardized system by chemical scientists for naming chemical compounds.

The IUPAC name for NH3 is Ammonia. Ammonia is a colorless gas with a stifling odor that is an exceedingly unpleasant pungent smell. It dissociates quickly in water to generate ammonium hydroxide, which can irritate and burn the skin.

Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.

A homogeneous mixture is defined as having a fairly uniform form and composition, so many homogeneous mixtures are referred to as solutions whereas heterogeneous mixtures are defined as separate substances or phases. The three states or states of matter are gas, liquid and solid.

Some examples of mixtures that include mixtures of sand and water, mixtures of sugar and salt, and mixtures of lime juice and water.

In homogenous solution, particles are distributed uniformly and have uniform composition while in heterogenous solution, particles are distributed non-uniformly and have non-uniform composition

Thus, Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.

Answer:

I think it's 2.50M IM NOT SURE THOUGH SO I RECOMMEND WAITING FOR ANOTHER ANSWER

Answer: false

Explanation:

Answer:

(5.00M)(X) = (0.120L)(0.470M)

X = (0.120)(0.470)/(5.00)

0.01128

Explanation:

12.1 M HNO3 would be needed to prepare 0.500 L of 0.500 M HNO3 stock solution is 0.01128 milliliters.

The ideal way to define stock solutions is as concentrated solutions with precise, known concentrations that will be diluted for later laboratory usage. Even though you may decide against making stock solutions, doing so may help you run your business more efficiently and save you a ton of time and money.

where C1 x V1 = C2 x V2. Stock concentration, C1 ( beginning concentration ) V1 is the amount of stock needed to make the new solution. C2 is the concentration of a fresh or effective solution.

( 5.00M ) ( X ) = ( 0.120 liter ) ( 0.470 M )

Then, X = 0.120 × 0.470 ÷ 5.00

= 0.01128 milliliters.

Thus, 12.1 M HNO3 would be needed to prepare 0.500 L of 0.500 M HNO3 stock solution is 0.01128 milliliters.

Answer:

A cation with a 2+ charge will make a stronger ionic bond than a cation with a 1+ charge. A larger ion makes a weaker ionic bond because of the greater distance between its electrons and the nucleus of the oppositely charged ion.

Answer:

c

Explanation:

Answer:

Atoms are the smallest particle that make up living both living and non living things, they are made up of subatomic particles; protons, neutrons and electrons. Of these the electrons protons and neutrons are in the nucleus and the protons electrons orbit around the nucleus. Of the subatomic particles, the electrons have the largest smallest mass and are negatively charged, the neutrons (negative charge) (no charge) and protons (positively charged) both have a relative mass of 1. Atoms contain an equal number of protons and neutrons electrons, so carry no overall charge. An element is a substance made up of only two one type of atom. Elements can be found in the Periodic table of elements, they usually have two numbers next to the chemical symbol, the larger number is generally the atomic mass number, which represents the number of neutrons and the number of protons. The smaller number is the relative atomic mass atomic number which represents the number of electrons or neutrons protons. In order to calculate the number of neutrons, you minus the atomic number from the relative atomic mass.

This question involves the concepts of de Broglie's wavelength and momentum.

The velocity of the electron must be "1754.27 m/s".

de Broglie's wavelength is a wavelength associated with a moving matter particle. It is connected to the momentum of the particle by the following formula:

[tex]P =\frac{h}{\lambda}\\\\mv=\frac{h}{\lambda}\\\\v=\frac{h}{m\lambda}\\\\[/tex]

where,

v = velocity of electron = ?

h = Plamk's Constant = 6.625 x 10⁻³⁴ J.s

m = mass of electron = 9.1 x 10⁻³¹ kg

λ = de Broglie's wavelength = 415 nm = 4.15 x 10⁻⁷ m

Therefrore,

[tex]v=\frac{6.625\ x\ 10^{-34}\ J.s}{(9.1\ x\ 10^{-31}\ kg)(4.15\ x\ 10^{-7}\ m)}[/tex]

v = 1754.27 m/s

This problem is giving information about a nylon polymer whose molar mass is 15,000 amu (atomic mass units).

The first subject of matter here, is to recall the monomeric molecular formula of nylon which is C₁₂H₂₂N₂O₂, and the definition of monomer (basic molecule able to react and form a polymer) and polymer (assembling of monomers).

Next, we calculate the molar mass of the monomer of nylon:

[tex]12*12.01+22*1.01+2*14.01+2*16.00=226.31amu[/tex]

Finally, the number of units is calculated by dividing the molar mass of the polymer and the monomers:

[tex]n=\frac{15000}{226.31} =66.2[/tex]

Which is about 66 monomers.

Molarity is the number of moles of solute in a unit volume.

The atomic masses of

C -12

H-1

O-16

Therefore molar mass ( mass of 1 mol ) of ethanol ( CH3CH2OH )

( 12 x 2 ) + (1 x 6) + 16 = 46 g/mol

In 10 g of ethanol 10/46 mol should be present

So the molarity is (10/46) mol ÷ 100ml

= 10/ 46 mol ÷ 0.1 l

1L = 1 dm3

Therefore molarity = 10/46 mol ÷ 0.1 dm3

= 2.17 mol/dm3
