Enthalpy question help need answer now?
Nitric oxide (NO) gas can be formed via the following reaction: 4NH3 (g)+5O2 (g)→4NO(g)+6H2O(l) Using Hess’s Law, calculate the enthalpy of the above reaction. (1) 1/2N2 (g)+3/2H2 (g)→NH3 (g) ΔH1 =-46.1kJ (2) 1/2N2 (g)+1/2O2 (g)→NO(g) ΔH2 =90.3kJ (3) H2 (g)+1/2O2(g)→H2O(l) ΔH3 =-285.8kJ a211.3 kJ b-1169.2 kJ c-1074.4 kJ d-241.6 kJ i keep getting b, but my test review says the answer is c

HELP!!!!!! I NEED AN ANSWER NOW!!! How much tulle should I but???
This is a simple math problem...If the chair is 14" wide, then (depending on how thick the back of the chair is) you would need approximate 30-32" just to get around the chair. Then you need enough left over to tie a nice bow. I'm going to say at least another 20-30". So that's roughly 5-6 feet of tulle per bow. 25 yards would make roughly 12-15 chair bows. So to make 100 bows, you'd need 9 rolls at 25 yds per roll.
HOMEWORK PLEASE HELP!! NEED ANSWERS NOW ! 10 POINTS FOR ANSWER.?
Orthographic drawings provide detail about sizes and layout of an object. An orthographic drawing will have all the views of an object e.g. Plan view, front view etc. Drawn to scale so as others could manufacture the object. Line types on working drawings:- Continuous thick line = outline Continuous thin line = projections Short dashes = hidden detail Long chain (dot, dash) = centre lines Continuous thin line with arrow heads = dimensions The purpose of orthographic drawings is to show a 3D object in 2D that gives accurate measurements and information. The idea is that anyone could use the drawings to make the object just as the designer intended. For Details check: http://en.wikipedia.org/wiki/Orthographic_projection Hope that helps buddy DT
Test cross- dna- please help need this answer now?
Ttxtt A test cross is used to determine the genotype of an individual that exhibits a dominant phenotype for a trait. In other words, it is used to find out whether the individual is hybrid or homozygous dominant for the trait. A test cross is performed by crossing the unknown with a homozygous recessive. If the offspring's phenotype is 100% dominant, then the unknown must have been homozygous dominant. If the offspring's phenotype is 1:1, then the unknown must have been heterozygous. (tt x tt does not constitute a test cross because tt is not an unknown individual exhibiting a dominant phenotype. tt is exhibiting the recessive phenotype. Thus, there is nothing to test, because it's genotype is already known. It must be homozygous recessive.)

How do I wake up a drunk person (I need the answer now)?
Well that's a tricky question and here is my experience. My husband of 8 years likes his beer and on top of that had a sleeping disorder where he wakes up 20 times in one night except when he falls asleep drunk. The times I've had to wake him I've used a bottle of my strongest perfume and waved it under his nose. Or I will sit him upright and comb his hair maybe put a little cold water on the brush it usually works. But most of the time it's his feet that will get him to open his eyes I either massage his feet or ankles and it startles him awake. Be careful a disturbed drunk can wake nasty so keep your distance from the arms they tend to flail lol. Good luck and let me k ow if any of my tips worked for you.

What is a proper response to 'May I help you?' if I don't need any help?
if you can form a sentence without using …..no & dont …it will sound more polite, however sales staff are not that senstive to a blunt no ….bcoz for them …offering help to the customer is a mechanical process(most of the times)now other scenario is ….you have a lot of things in your hand ..which you are trying to manage some how …..and some one asked you this question….u need to be really nice …as they are not bound to offer help …but as a nice human being if they are offering help….which you dont want to take …….your response should not sound as a denial ……it should be an acknowledgemnt of their niceness….so with a big smile you can say “thank youindian context: if you are girl waiting for a bus or any other place , and a cheap looking guy, or even a nice looking guy (who is cheap inside) stops his bike or car in front of you ….and asks the same question…may i help you ….appropriate response could be …should i call 1090 ……or another one ,…..saale jaake apni behan ko help kar…
