I'd use the caustic soda for making soap. Thanks.

1. Person A sprints around a circular track of radius 100m at a constant speed of 7m/s. Person B is standing at a distance 200m from the center of the track. How fast is the distance between the 2 changing when the distance between them is 200m?

2. Show that the volume of the sphere is decreasing at rate proportional to its surface area then the radius of the sphere is shrinking at a constant rate.

What are the half reactions and over-all reaction for electrolysis of water which uses baking soda aqueous solution as an electrolyte?

Also, explain please why baking soda aqueous solution is used as electrolyte in the electrolysis of water.

1. Some strands of Christmas tree lights are wires in series. What happens to the other lights if one of the bulbs is removed? Other lights are wires in parallel. What happens to the other lights if one of the bulbs is removed?

2. Knowing that the ammeter must be connected in series with the circuit and the voltmeter must be connected in parallel, what does this tell you about the internal resistance of each device?

1. If a strong acid has a pH of 1, a strong base has a pH of 14, and water has a pH of 7, does catalase work best in an acid, base, or neutral environment? Explain.

2. Predict ways in which pH affects the chemical reactions in living cells.

You happen to take a swim in an ocean populated with stonefish or lionfish. These organisms are known to inject venom to their prey or when they are threatened. What will you do if you were exposed to its venom? How will you initially remove the venom to avoid serious reactions? (*note: our topic is about proteins)

1. What happens during meiosis that ultimately results in a defect characterized by the addition of chromosomes? By the deletion of chromosomes?

2. The human male determines the sex of his offspring. Explain this statement.

If a bottle of carbonated soft drink is left open, the taste of the soft drinks goes "flat". Why? Explain how reversible reaction is applied in this phenomenon.

1.) What might be the outcome of the cell cycle if the chromosomes will not change structure?

2.) With all the chemicals the body takes in everyday both good and bad, what might be the effect of these in the cell cycle and the chromosomes?

3.) Why are there different structures of chromosomes as the cell undergo the cell cycle?

In the box of the Guitar Hero World Tour, there are tons of songs listed, but when i started playing, there were only 24 song. Songs like the "Misery Business", "Hotel California" and many more weren't available or weren't even on the lst of songs. Why is this so? How can I make these songs available?

When I woke up this morning is looked at the mirror but this mole was not yet in my forehead. Then, after I eat and take a bath, I brushed my teeth and when I saw myself in the mirror it was there already. I tried to remove it but it was really in the skin. It is just flat and like a brown pigment but it really bothers me.

How and why did this happen? Will it be permanent or will it lose? Is this normal? Is this really a mole?

Is it for free because no one or no site is selling tickets yet? If it's not for free, where can I buy tickets? Or how can I get tickets for the concert?

1.) The forward motion of a bullet shot from a gun causes a recoil of the gun, just as jumping of a person from a rowboat to a dock cause the boat to be pushed backward. Explain why this is so.

2.) If the reaction is of equal magnitude to the action, why don't you observe your ping-pong paddle recoil when it strikes the ping-pong ball?

3.) During an interaction between a 12-kg object and a 40-kg object, the 12-kg object experiences as eastward acceleration of 2.5 m/s^2. What is the acceleration of the 4- kg object?

1.) A skydiver jumps from a plane and plummets towards the earth. His or her speed does not increase indefinitely but reaches a terminal speed of 120 miles per hour. Explain why. (static and sliding friction)

2.) When riding a horse, a jockey stands in the stirrups, legs flexing with each stride of the horse. Dirt bike riders do the same as they travel over bumpy terrain. Explain in terms of impulse and momentum.

3.) When jumping off a wall or rock you stand land with legs bent rather than straight. Why?

4.) A swimmer who jumps from a high diving board can enter the water and sustain no injury. The same person jumping from the same height and landing on concrete may not live to tell about it. Explain in terms of impulse and momentum.

WHY???!!! Where and how would they pick the 3 contestants to complete the top 12?

How is this associated with meiosis?

Hexane is an alkaline hydrocarbon with the chemical formula CH3(CH2)4CH3 or C6H14. The "hex" prefix refers to its six carbons, while the "ane" ending indicates that its carbons are connected by single bonds. Hexane isomers are largely nonreactive, and are frequently used as an inert solvent in organic reactions because they are very non-polar. They are also common constituents of gasoline and glues used for shoes, leather products, and roofing. Additionally, it is used in solvents to extract oils for cooking and as a cleansing agent for shoe, furniture and textile manufacturing. In laboratories, hexane is used to extract oil and grease from water and soil before determination by gravimetric analysis or gas chromatography.
