How do the products and reactants of a chemical change compare?
Q. 1. The mass of the products is greater than the mass of the reactants because energy is absorbed by the reaction. 2. The mass of the products equals the mass of the reactants because energy is not absorbed or given off by the reaction. 3. The mass of the products is less than the mass of the reactants because energy is given off by the reaction. 4. The mass of the products equals the mass of the reactants because the same atoms are present throughout the reaction.

Example - Product X sells for $100 each and Y sells for $120 each. Product X fixed cost of $2000 per year and variable cost of $12 per unit, whereas product Y has fixed cost of $8000 and variable cost of $40 per unit. At what production rate (volume) are the profits from both products equal ?

A. 1500 units x=$88 profit y=$80 profit x requires 227.27 units to break even @ 227.27 units, y profits $10,182 Since profit for x >y by $8, x will "catch" y in 1,273 units. (228 unit=break even for x) + (1273=units x to "catch" y) = 1500 You can do the double check on your own :)

A. I guess what you are asking is what useful products are made from poisonous starting materials. The best example I could give you is polycarbonate (Thick- clear plastic - sparklets water bottles). They use phosgene and bisphenol-A. Bisphenol-A is a diphenol and phosgene is a deadly poison (COCl2) ref: ref: COCl2 + HO-R-OH --> --((C=O)-O-R-O-)-- ref: There are many other polymers made with toxic monomers. Hexamethylene diamine used to made nylon is highly toxic: ref: NH2(CH2)4NH2 + COOH(CH2)4COOH --> --(COHN(CH2)6NHCO(CH2)4-) - ref: ref: there are countless other examples - these are just two..

Asked by mo - Thu Jan 28 06:04:10 2010 - - 1 Answers - 0 Comments

A. Hi, mo The use of skin care oils or natural skin care products does not depend upon the colour of your complexion. It depends upon the texture of your complexion. If you have acne then there are chances of your skin being oily. Therefore, for oily skin or acne prone skin skin you should drink green tea. Secondly, you must drink 1-2 litres of water everyday for clearing the toxins and bacteria. Try to refrain from using oil on your face because it is already oily. There are other good remedies in this article; "How to get rid of acne. I have provided the link below for you to see. I hope it helps :)

A. I've found hair conditioner works better than any shaving product I've tried. And, if you're naturally hairy and shave a lot of places, having it come in a big pump bottle to use in the shower is a bonus. I also switched to hair conditioner for shaving my face after reading about it online (maybe here on Yahoo Answers?) - heaps less irritation, and even a smoother shave. I use a Mach 3 razor (because the newer ones cost too much), and I try to change the razor after about three full shaves (legs, armpits, chest, face), when you shave a lot, it gets blunt quickly. This will depend on how hairy you are. I also find that, using hair conditioner, I usually don't need any kind of after shave lotion, but sometimes use my girlfriend's Avene… [cont.]
