Taste and colour of water is different in both 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. The water in the plastic bowl taste more like regular water it does not have a taste but the water in the pot has a biterness taste to it.

Explanation:

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 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.

Image result for What evidence in Side View lets you know that upwelling is happening in these locations?

Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling.

Explanation:

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]

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

Answer:

If a mineral with a density of 6 g/cm3 is broken into 3, the density of each new piece is 6 [tex]\frac{g}{cm^{3} }[/tex]

Explanation:

Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. In other words, density is the property that matter, whether solid, liquid or gas, has to compress into a given space, the amount of mass per unit volume.

As density is a physical property of matter that is defined as the ratio of an object's mass to its volume, each material or substance has its own density regardless of its size because the ratio between mass and volume is the same.

If a mineral with a density of 6 g/cm3 is broken into 3, the density of each new piece is 6 [tex]\frac{g}{cm^{3} }[/tex]

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

Answer:

87.5 mi/hr

Explanation:

Because a = Δv / Δt (a = vf - vi/ Δt), we need to find the acceleration first to know the change in velocity so we can determine the final velocity.

vf = 60 mi/hr

vi = 0 mi/hr

Δt = 8 secs

a = vf - vi/ Δt

= 60 mi/hr - 0 mi/hr/ 8 secs

= 60 mi/hr / 8 secs

= 7.5 mi/hr^2

Now that we know the acceleration of the car is 7. 5 mi/hr^2, we can substitute it in the acceleration formula to find the final velocity when the initial velocity is 50 mi/hr after 5 secs.

vi = 50 mi/ hr

Δt = 5 secs

a = 7.5 mi/ hr^2

a = vf - vi/ Δt

7.5 = vf - 50 mi/hr / 5 secs

37.5 = vf - 50

87.5 mi/ hr = vf

And further explain the panic you felt and how the atmosphere changed

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

Answer:  True

Explanation: Transferring energy to or from a substance can change its state. Heating a substance in the solid state will cause it to melt, which changes it to the liquid state. Continued heating will cause the substance to evaporate or boil, which changes it to the gas state.

Some substances in the solid state can change straight to the gas state. This process is called sublimation.

A substance in the gas state condenses when it is cooled, which changes it to the liquid state. Continued cooling causes it to freeze, which changes it to the solid state.
