Answers

Taste and colour of water is different in both pot and plastic bowl.

Comparison between water in pot and plastic bowl

The appearance of the water in the pot is different from that of the water in the plastic bowl because of the colour. We know that water adopt the colour of the container in which it has been kept.

The taste of water in the pot is somewhat sweeter and colder than water present in the pot due to presence of pores and composition of pot so we can conclude that taste and colour of water is different in both pot and plastic bowl.

Answer: The water in the pot is fully red because  it is being heated the color is spreading more and the water in the pot is clear because condensation leaves the color and salt behind.

An atom can be called a particle, but a molecule is never called a particle.

Answers

Answer:

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]

A student add sodium hydroxide (NaOH) to the solution equilibrium. In 1 to 2 sentences describe and explain any changes to the solution that the student will observe.

Answers

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

Equilibrium position

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.

Calculate the pH during the titration of 30.00 mL of 0.1000 M NaOH(aq) with 0.1000 M HCl(aq) after 18.51 mL of the acid have been added.

Answers

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

Calculate the pH value during the titration

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

Match the correct type of energy transfer that takes place.

Answers

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.

5.1169 mol of Ne is held at 0.9148 atm and 911 K. What is the volume of its container in liters?

Answers

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

Boyle's  Law

Given Data

number of moles of Ne = 5.1169 mol Pressure = 0.9148 atmTemperature = 911 K

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

HNO3(aq)+H2S(s)> Ss)+ NO(g)+H2O(l)

Answers

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.

A rock falls from a cliff and travels downward for 6 seconds before striking the ground. How fast was the rock moving when it hits the ground? Assume there is no air resistance.

Answers

Given parameters:

duration of fall  = 6s

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
