Proton has positive charge whereas neutron has no charge.

What are the difference between a proton and neutron?

Proton is a type of subatomic particle that has a positive charge whereas Neutron is a type of subatomic particle that has no charge.

An atom that has lost one or more number of electrons is known as anion.

Isotopes is defined as an element that have the same number of protons i.e. atomic number but different numbers of neutrons i.e. mass number.

Electron is located outside the nucleus of an atom.

Fluorine is that atom which has 9 number of protons so its atomic number is 9.

Atomic number is related to the number of particles in the nucleus of an atom because in the nucleus, proton is present which shows the atomic number of an atom.

There are three parts of an atom i.e. proton, electron and neutron.

The size of electron is about 2 × 10⁻¹⁰ cm, The size of proton is about 0.84×10⁻¹³ cm and the size of neutron is about 1.7×10⁻¹⁵ meters

Electron has negative charge, proton has positive charge and neutron has no charge.

Yes, we can tell about the element if we know about the charge and the number of electrons in it because different atoms has particular number of electrons.

The diameter of a nucleus in scientific notation is 1.6 x 10⁻¹⁵.

The mass of hydrogen atom in whole number is 0.00000000000000000000000000167.

How will you show that carbon dioxide is havier than air?​

Answers

Answer:

There's an experiment that you can try to see if carbon dixide is heavier than air.

Explanation:

At room temperature, carbon dioxide has higher density (ρ = 1.98 kg·m -3) than air (ρ = 1.29 kg·m -3). The density of gas, however, significantly depends on its temperature. Carbon dioxide produced by burning has higher temperature than the surrounding air.

Why is CO2 heavier than the air?

Short answer is CO2 is heavier than ambient air, but it does not drift to the ground as there is a lot of mixing going on in ambient air. ... Carbon dioxide, also known by the chemical formula CO2, has a higher density than the other gases found in air, which makes CO2 heavier than the air.

when 15.0 g
of steam drops in temperture from 275.0°C
to 250° C, how much heat. energy is released?

Answers

Answer: The amount of heat needed to raise a substance's temperature by one Kelvin per kilogram. The heat needed to raise the temperature of a given substance with known mass can be calculated as follows:

                                      ΔH=mCΔT

ΔH=Amount of heat energy supplied

m=Mass of the substance = 15 g

ΔT=Change in temperature = Tfinal−Tinitial = 250° C - 275.0°C = -25°C

C=Specific heat capacity = 2.02 J/g °C

               ΔH=mCΔT

after putting the given values,

                ΔH= -757.5 J

The formula also shows that heat energy is released (negative value) when the change in temperature is negative, i.e., when the temperature of a substance falls.

      An ion is an atom or collection of atoms where the number of electrons and the number of protons are different. A positive ion, also known as a cation, is a particle that exists when the number of electrons exceeds the number of protons.

What does an atom's ion mean?

      Because they have an equal number of protons and electrons, atoms are neutral particles. Ions are electrically charged particles that can be created by either taking electrons away from neutral atoms to form positive ions or adding electrons to neutral atoms to produce negative ions.

What makes something an ion?

    Depending on whether the number of electrons in an atom is greater or less than the number of protons in the atom, an atom can develop a positive charge or a negative charge. An atom is referred to as an ION when it is drawn to another atom due to an imbalance in its electron and proton numbers.

An ion is it an element?

    Any element that has a variable ratio of protons to electrons, producing either a positively or negatively charged atom, is said to contain an ion. It is relatively easy to determine whether an element is an ion.

How come ions originate in elements?

Answers

By ideal gas approximation, the volume change is 230.2 liters.

We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation

P . V = n . R . T

where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.

From the question above, we know that

n₁ = 1 mol

n₂ = 1 + 9 mol = 10 mol

P₁ = P₂ = 100 kPa = 100000 Pa

T₁ = 74⁰ C = 347 K

Find the initial volume

P₁ . V₁ = n₁ . R . T₁

100000 . V₁ = 1 . 8.31 . 347

V₁ = 0.0288 m³

When the initial and final temperature and pressure are the same, we can use the ratio of the number of moles and volume as

V₁ / n₁ = V₂ / n₂

0.0288 / 1 = V₂ / 9

V₂ = 0.25952 m³

V₂ = 259.52 liters

The volume change is

ΔV = V₂ - V₁

ΔV = 259.52 - 28.8

ΔV = 230.2 liters

at standard pressure, water has unusual properties that are due to both its molecular structure and intermolecular forces. for example, although most liquids contract when they freeze, water expands, making ice less dense than liquid water. water has a much higher boiling point than most other molecular compounds having a similar gram-formula mass. determine the total amount of heat, in joules, required to completely vaporize a 50.0-gram sample of h2o( ) at its boiling point at standard pressure.

Answers

The heat required to vaporize this sample at standard pressure is 113,270 J.

We can calculate the amount of heat (Q) needed to vaporize 50.0 grams of water by using water's heat of vaporization (q) at 100 °C (boiling point of water) - 40.8 kJ/mol, and the number of moles of water (n).

Q = n * q

The heat of vaporization describes the amount of energy needed to be introduced to a single mol of water at 100 °C to break the intermolecular interactions between molecules of water so it changes to a gaseous state.

To calculate the number of moles of water, we are going to use the mass of water (m = 50.0 g) and its molar mass (M = 18.01 g/mol):

n = m/M

n = 50.0 g / 18.01 g/mol

n = 2.7762 mol

Now we can calculate the amount of heat needed:

Q = 2.7762 mol * 40.9 kJ/mol

Q = 113.27 kJ

Q = 113,270 J

6.11 D

Answers

The dipole moment of the hydrogen bromide HBr molecule is equal to 6.77 D. Therefore, option (C) is correct.

What is a dipole moment?

A dipole moment can be determined from the product of the magnitude of the charge and the distance between charges and is represented by the Greek letter ‘µ’.

The bond dipole moment arises between two atoms of different electronegativities in a chemical bond.

μ = q × d

Where: μ is the bond dipole moment, q is the magnitude of the partial charges, and d is the distance between them.

Given, the bond Length of HBr = 1.41 A° = 1.41 × 10⁻¹⁰ m.

The charge on H and Br atoms =  1.6 × 10 ⁻⁹ C

Therefore,

Dipole Moment of HBr =  Distance × Charge

Dipole Moment =  1.41 × 10⁻¹⁰ ×  1.6 × 10 ⁻¹⁹

Dipole Moment = 2.25882 × 10⁻²⁹ C.m  

The conversion factor of one-coulomb meter is equal to 2.9989  ×10⁻²⁹ Debye

Therefore,

Dipole Moment = 2.25882  ×10⁻²⁹ × 2.9989  ×10²⁹

how many moles and how many ions of each type are present in each of the following? (a) 88 ml of 1.75 m magnesium chloride (b) 321 ml of a solution containing 0.22 g aluminum sulfate/l (c) 1.65 l of a solution containing 8.83×1021 formula units of cesium nitrate per liter

Answers

a. The number of moles = 0.154 moles and number of ions =2.78x10²³ ions.

b. The number of moles= 2.18x10⁻⁴ moles and number of ions = 6.56x10²⁰ ions.

c.  The number of moles= 0.0147 moles and number of ions = 1.77x10²² ions .

Calculation of the no of moles and no of ions:

A. Moles MgCl₂:

According to question

88mL = 0.088L * (1.75mol / L) = 0.154 moles MgCl₂

By using (Avogadro's number:)

So,

0.154mol  *(6.022x10²³ molecules / 1 mol) = 9.27x10²² molecules.

Since 1 molecule of MgCl₂ contains 3 ions:

So,

Ions = 2.78x10²³

B. Moles Al₂(SO₄)₃:

( Aluminum sulfate , molar mass = 324.15g/mol:)

So,

0.321L * (0.22g Al₂(SO₄)₃ / L) * (1mol / 324.15g) = 2.18x10⁻⁴ moles.

Now,

1 molecule contains 5 ions:

So,

2.18x10⁻⁴ moles  *(6.022x10²³ molecules / 1 mol) * 5 = 6.56x10²⁰ ions.

C. Since

8.83x10²¹ formula units of CsNO₃ = Number of molecules. Ions are:

So,

8.83x10²¹ * 2 = 1.77x10²² ions

And moles are:
