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]

Match the correct type of energy transfer that takes place.
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?
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 LawGiven Data
number of moles of Ne = 5.1169 mol Pressure = 0.9148 atmTemperature = 911 KWe 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

Give a reason why it might be important to know Newton’s second law in the real world.
Answer:
Newton's Second Law states that an object's acceleration depends on the net force upon the object, as well as the object's mass.
So, a real world example of this would be pushing a vehicle out of a ditch. If your vehicle is a motorcycle, with a relatively small mass, then you don't need to apply much force on it, as compared to if the vehicle were a pickup truck, with a large mass, which would require much more force applied to move it out of the ditch.

CrO42-+2H+=Cr2O7^2-+H2O
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.
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.

Compare the appearance of the water in the pot with that of the water in the plastic bowl. What do you notice? Next, taste the water in the plastic bowl. Compare the taste with the sample of water you tasted earlier from the pot. Does the water taste similar or different? Explain.
Taste and colour of water is different in both pot and plastic bowl.
Comparison between water in pot and plastic bowlThe 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.

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.
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 titrationFirst 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

An atom can be called a particle, but a molecule is never called a particle.
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.
HNO3(aq)+H2S(s)> Ss)+ NO(g)+H2O(l)
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.

bond energies in electron volts (ev), and their melting points. use the pattern
indicated in the table to predict the average bond energy of calcium fluoride (caf2
), which has a melting point of 1420°c.
The bond energy is the energy that must be supplied to break the bond. Ionic substances are held together by strong bonds.
What is bond energy?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.
