Explanation:

The charged particles of nucleus are protons while neutrons are neutral having no charge.

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus.

Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.

Symbol of proton= P⁺  

Symbol of neutron= n⁰  

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons.

one proton contribute 1 amu to the total weight. There are 20 protons and 20 neutrons in Ca thus its atomic mass is 40 amu.

While the atomic number is 20.

1.58 102 mol

Explanation:

I just looked it up on Quizlet.

1.58 102 moles of NaOH must be dissolved in 1.00 L of water to make NaOH (aq) with a pH of 12.2.

One mole of any substance weighs about the same as the molecular mass of that substance. Hence, the number of moles of sodium hydroxide contained in 160 g of it is 4 moles.

Number Of Moles Formula

1 The formula for the number of moles formula is expressed as.

Given.

2 The number of moles formula is.

3 The number of moles = Mass of substance / Mass of one mole.

4 Number of moles = 95 / 86.94.

Explanation:

Explanation:

Methane is a gas at room temperature but methanol is a liquid because in methane there's London dispersion intermolecular force but in methanol there's H-bond and London dispersion force. H-bond is more stronger than London dispersion force. So, it increases the boiling point of methanol that's why methane is gas at room temperature due to weak attraction of London dispersion force and methanol is liquid.

Methanol has a higher boiling point than methane due to stronger intermolecular forces (IMFs), or attraction between individual molecules. This makes its molecules more difficult to separate, requiring more energy and resulting in a higher boiling point.

An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.

Intermolecular forces are classified into five types namely,

Between ions and polar dipole molecules, ion-dipole forces exist.

Since of stronger intermolecular forces (IMFs), or attraction between individual molecules, methanol has a higher boiling point than methane.

This makes it more difficult to separate its molecules, requiring more energy and resulting in a higher boiling point.

Thus, this is the reason of using types of intermolecular forces present.

Answer:

ΔG =   18KJ/mol

Explanation:

Given data:

ΔS = 0.09 Kj/mol.K

ΔH = 27 KJ/mol

Temperature  = 100 K

ΔG = ?

Solution:

Formula:

ΔG = ΔH - TΔS

ΔS = entropy

ΔH = enthalpy

by putting values,

ΔG =  27 KJ/mol - 100K(0.09 Kj/mol.K)

ΔG =  27 KJ/mol - 9 KJ/mol

ΔG =   18KJ/mol

Answer:

ΔG = 18kJ/mol

Explanation:

took the quiz on ap ex and it was correct

Answer:

Hydrogen bond strengths range from 4 kJ to 50 kJ per mole of hydrogen bonds. In molecules containing N-H, O-H or F-H bonds, the large difference in electronegativity between the H atom and the N, O or F atom leads to a highly polar covalent bond (i.e., a bond dipole).

One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.

Explanation:

Students were asked to describe evidence of Plate Tectonic Theory.

descriptions listed above accurately describe evidence supporting Plate

Tectonic Theory. Student 3 describes "glacial evidence indicates that different continents were once connected near the South Pole."

The widely recognized scientific hypothesis known as plate tectonics states that the Earth's lithosphere was made up of many major tectonic plates that have already been gently migrating since around 3.4 billion years ago.

The south pole would be one of two locations on Earth's surface at which the planet's axis of rotation crosses it. It is often referred to as one of the Geographic south pole, Terrestrial South Pole, and 90th Parallel South.

The fossil record is such sort of evidence that has been used to support the Claim of Continental Drift. On the coastlines of many continents, fossils of specific kinds of plants, as well as animals have been discovered in rocks that are comparable in age, indicating that the continents had been connected.

Answer:

Molecular formula = C₈H₁₆

Explanation:

Given data:

Percentage of hydrogen = 14.4%

Percentage of carbon = 85.6%

Molecular formula = ?

Molecular weight = 112 g/mol

Solution:

Number of gram atoms of H = 14.4/ 1.01 = 14.26

Number of gram atoms of C = 85.6/ 12 = 7.13

Atomic ratio:

            C                      :              H        

           7.13/7.13            :           14.26/7.13    

            1                      :                 2          

C : H = 1 : 2

Empirical formula is CH₂

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

n = 112 / 14

n = 8

Molecular formula = n (empirical formula)

Molecular formula = 8 (CH₂)

Molecular formula = C₈H₁₆
