Explain The difference in motion of Atom in the following states of matter solid liquid and gas which of the states has the slower moving atom and which one has the fastest

Answer:

Lightbulb: electrical energy to light energy

Alarm Clock: electrical energy to sound energy

Rollercoaster: electrical energy to mechanical energy

Riding a Bike: chemical energy to mechanical energy

Explanation:

Light bulbs, alarm clocks, and roller coasters require electrical energy to work. This energy then changes into the subsequent types. Light bulbs primarily emit that energy in the form of light, alarm clocks change that energy into sound, and roller coasters begin to move (mechanical). People power bikes, and the energy in our body is stored as chemical energy. So, when we rides bikes, that energy gets turned into moving (mechanical) energy.

By applying the Boyle's equation and substituting our given data the volume of the container was found to be 418.14 Litres

Given Data

We know that the relationship between pressure and temperature is given as

PV = nRT

R = 0.08206

Making the volume subject of formula we have

V= nRT/P

Substituting our given data to find the volume we have

V = 5.1169*0.08206*911/0.9148

V = 382.522353554/0.9148

V = 418.14 L

The pH during the titration 30.0 mL OF 0.1000 M NaOH(aq) with 0.1000 M HCl(aq) of after 18.5 mL of the acid is added is : 12.38

First step : Determine the number of moles

Number of moles of NaOH = 0.1000 M * 30.00 mL = 3.0 mmol

Number of moles of HCl = 0.1000 M * 18.5 mL =  1.85 mmol

The net moles of NaOH = 3.0 mmol - 1.85 mmol = 1.15 mmol

Next step :

The total volume of the solution = 30.00 + 18.51  = 48.51 mL

[ NaOH ] = [ OH⁻ ] = net moles / total volume

                             = 1.15 mmol / 48.5 mL = 0.023711 M

Final step : Determine the pH value

pOH = – log[OH⁻] = – log ( 0.023711 )

                             = 1.625

Therefore :

pH value = 14 - pOH

               = 14 - 1.625 ≈ 12.38

Hence we can conclude that The pH during the titration of after 18.5 mL of the acid is added is : 12.38

The bond energy is the energy that must be supplied to break the bond. Ionic substances are held together by strong bonds.

This question is incomplete but I will try to explain what is meant by average bond energy as the tables are missing.

The average bond energy of a bond simply means the energy that is stored in that bond as it holds two atoms together. It is equal to the energy that must be supplied to break the bond. The numerical value of the bond energy can not be deduced as the data is missing.

Answer: Nitric acid + Hydrogen disulfide

Explanation: To balance HNO3 + H2S = NO + S + H2O you'll need to be sure to count all of atoms on each side of the chemical equation.

Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Nitric acid + Hydrogen disulfide .

Important tips for balancing chemical equations:

Only change the numbers in front of compounds (the coefficients).

Never change the numbers after atoms (the subscripts).

The number of each atom on both sides of the equation must be the same for the equation to be balanced.

When the glass rod is rubbed with a silk cloth,  The glass quickly loses electrons, and the silk takes the electrons out of the glass rod. So after rubbing, the glass rod becomes positively charged and the silk gets negative charge. So glass acquires a greater order than silk as electron losses.

Explanation:

the reactions at the cathode:

1. the reduced active metal is water, other than that the metal will be reduced

2. H⁺ of the acid will be reduced

the reactions at the anode:

1. if the electrodes are not inert then the metal is oxidized

2. If inert then:

a. OH⁻ from the base will be oxidized

b. The halogen metal will oxidize

1. HCl

H⁺ of the acid will be reduced

Cathode: 2H⁺(aq) + 2e⁻ ⇒ H₂(g)

The halogen metal will oxidize

Anode: 2Cl⁻(aq) ⇒ Cl₂(g) + 2e⁻

2. NaNO₃

Na : active metal, water reduced

Cathode: 2H₂O + 2e ⇒ 2OH- + H₂

NO₃: oxyacid, water will be oxidized

Anode: 2H₂O ⇒ 4 H + + O₂ + 4e

3. CuCl

Cu : not active metal

Cathode: Cu²⁺ (aq) + 2e ⇒ Cu (s)

Cl : The halogen metal will oxidize

Anode: 2Cl⁻ (aq) ⇒ Cl₂ (g) + 2e

Unknown:

Speed of the rock before it hits the ground  = ?

Solution:

To solve this problem, we apply one of the appropriate motion equations;

           V = u + gt

Where V is the final velocity

           u is the initial velocity

           t is the time taken

           g is the acceleration due to gravity  = 9.8m/s²

The initial velocity is 0;

     So;

              V = gt

Input the parameters and solve for V;

                V = 9.8 x 6  = 58.8m/s

The velocity before hitting the ground is 58.8m/s

Atoms are composed of particles called protons, electrons and neutrons. ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. Protons and neutrons are both composed of other particles called quarks and gluons.

Particles can be atoms, molecules or ions. The term molecule is often used incorrectly to refer to any type of chemical compound. A molecule is a neutral particle made of two or more atoms bonded together. Take care with your own language, especially when referring to compounds formed during chemical reactions.

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.[2][8] These contrast with benign tumors, which do not spread.[8] Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements.[1] While these symptoms may indicate cancer, they can also have other causes.[1] Over 100 types of cancers affect humans.[8]

Tobacco use is the cause of about 22% of cancer deaths.[2] Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol.[2][9][10] Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants.[3] In the developing world, 15% of cancers are due to infections such as Helicobacter pylori, hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV).[2] These factors act, at least partly, by changing the genes of a cell.[11] Typically, many genetic changes are required before cancer develops.[11] Approximately 5–10% of cancers are due to inherited genetic defects.[12] Cancer can be detected by certain signs and symptoms or screening tests.[2] It is then typically further investigated by medical imaging and confirmed by biopsy.[13]

Addition of NaOH will cause the equilibrium position to move to the left because of the removal of the hydrogen ions.

When changes in temperature, pressure or concentration is imposed on a reaction system in equilibrium, the system will readjust itself in order to annul the change.

This change occur when the equilibrium position is moved to the left or right. For the reaction, CrO4^2-+ 2H^+ ⇄ Cr2O7^2- + H2O, addition of NaOH will cause the equilibrium position to move to the left because of the removal of the hydrogen ions.
