What is the purpose of adding a buffer in the titration of the solution containing Ca2+ ions with EDTA solution?

Our professor asks us to watch an episode of Fringe where they used the concepts of sound waves. So I need help what that episode might be.

Suppose that a ball dropped from a building bounces off the pavement and that on each bounce it returns to a certain constant percentage of its previous height. Write a program to read the height from which the ball was dropped, the percentage rebound, and the number of bounces. Then for the given number of bounces, print the height of the ball at the top of each bounce, the distance traveled during that bounce, and the total distance traveled thus far. The ball is ‘at rest’ when the height is less than 1/2 an inch.

>>how do you do it? at least an advice or a tip/s.. thanks..

Nitroglycerine is an explosive used by the mining industry. It detonates according to the following equation: 4C3H5N3O9 (l) -----> 12CO2 (g) + 6N2 (g) + 10H2O (g) + O2 (g) What volume is occupied by the gases produced when 2.00 g of nitroglycerine explodes? The total pressure is 755 mm Hg at 455'C.

2. A small scale businessman took out a P500,000 loan at 8.7% interest compounded monthly.

(a) How long will it take to pay off the loan with monthly payments of P4,500?

1. Suppose you can obtain an 8-year bank loan at an interest rate of 9% compounded quarterly and you have determined that you can afford to make payments of P5,000 each quarter. How much can you afford to borrow?

5. A farmer can use two types of plant food, mix A and mix B. The amounts (in grams) of nitrogen, phosphoric acid, and potash in a cubic meter of each mix are given in the table. Tests performed on the soil in a large field indicate that the field needs at least 840 grams of potash and at least 350 grams of nitrogen. The tests also indicate that no more than 630 grams of phosphoric acid should be added to the field. A cubic meter of mix A costs P70 and a cubic meter of mix B costs P90. How many cubic meters of each mix should the farmer add to the field in order to supply the necessary nutrients at minimal cost?

Grams per cubic meter

Mix A Mix B

Nitrogen 10 5

Potash 8 24

Phosphoric acid 9 6

I can't decide whether to take BS mathematics or BS physics. I like math because it is less on memorization otherwise in physics which has chemistry in it which requires much memorization but it is interesting. In math, you only see a great percentage of numbers and that's what makes it a little boring unlike the latter.

Any advice?

At the same moment, two trains leave Chicago and New York. They move towards each other with constant speeds. The train from Chicago is moving at speed of 40 miles per hour, and the train from New York is moving at speed of 60 miles per hour. The distance between Chicago and New York is 1000 miles. How long after their departure will they meet?

MSG or monosodium glutamate can contribute to the production of cancer cells but is it conducive to stupidity?

My algebra teacher once said that students must avoid junk foods for the main reason that it contains MSG. I'm really curious if that's a fact.

I have this friend of mine who's being bullied like everyday. Like saying bad words whenever he speaks to him and leaving rough comments in social sites like facebook. Now I notice my friend to be more reticent and timid as before. Maybe frightened to whatever that "monster" would say to him.

I've watched a really cool and awesome anime called 'Fullmetal alchemist: Brotherhood' and it emphasized that pride is the most deadliest desire. I want to know other opinions about that. It has been said that pride can lead to a downfall and that "truth" is what gives people despair when they have become arrogant.

I noticed that whatever the nerds do they still ended up in being a loner.
