How to Calculate the Energy Released for an Electron in the Hydrogen Atom?
By admin | November 4, 2008
I’m extremely rusty in chemistry seeing as how I took Chem111 during my freshman year and am now a junior taking Chem112 and am having problems with this problem.
Calculate the energy released for an electron in the hydrogen atom that undergoes a transition from n = 2 to n = 4.
Multiple Choice Answers:
a. 4.09 X 10-19 J
b. 8.39 X 10-20 J
c. 7.46 X 10-32 J
d. 3.29 X 10-18 J
e. 5.39 X 10-21 J
Now, am I doing this right and using the correct formula?
I’m using the formula Ephoton = hv = hRH (1/n^2(low) - 1/n^2(high)) where hRH is 3.290⻪^15 s^-1
so I get:
hv=3.290⻪^15 s^-1 (1/4 - 1/16)
hv=3.290/0.1875
hv=17.54667
conversion to Joules:
17.54667 x 6.2415⻪^18 = 1.095 x 10^20???
It’s all wrong so I threw it up there for someone to pick it apart and show me where I was wrong and if you could kindly show me the correct way, thanks!

Under certain conditions of temperature and pressure Rate of formation of ammonia is 0.001 kg/ hr . What is the rate of conversion of Hydrogen under same conditions ? Please solve the problem step by step and justify each step, I shall be highly obliged if this problem is solved. Thank You In Advance.

Ivory asked:
energy released in the formation of 1 mol H2 from hydrogen atoms? The bond energy of H2 is 435 kJ/mol
The answer is 1400g
But i dont know how they got that. What formula or conversion factor are we sopposed to use. Im so confused. Please help

I loved the article on the Hydrogen cars coming our way in the near future. I am confused about Hydrogen technology and am hoping you can shed light (thru e-mail or another article) on why we can’t have a hydrogen converter installed on the car directly instead of depending on Hydrogen refill stations? As I comb the internet, I see many “home-grown” versions using Brown Gas extrapolated from water via a homemade heating system. It seems safe enough and doesn’t require a user to refill at a Hydrogen station. In fact, the user only has to refill the water every other month or two. Why are we not seeing these “add on” hydrogen kits being sold now via dealerships to augment current gas engines?

Should You Be Investing In A Hydrogen Car Kit?
By admin | September 10, 2008
What used to be absolutely out of reach in terms of cost is now readily available because of the new widespread use of Hydrogen car kit technology. With this introduction of this technology, comes a greater chance for more to start using the great power of Hydrogen as an renewable energy source. The effects of more people being able to use this technology are huge. In fact we are really now in need of coming up with a stable and renewable energy resource to replace oil.
Not only does the use of hydrogen as a fuel have all the associated environmental benefits, but also people who are using this technology are also saving up to 60% of their gas bills week in week out. You wouldn’t have to be a genius to work out that most people are buying up this technology in order to save themselves money on the costs of gasoline for their car. For Whatever reason that people begin using this technology is not really the case.
The only thing that really matters here is that we see what a great opportunity we have here with this technology, and begin to use it as much as we possibly can.

is this a marketing ploy? I know much “greener” cars?
By admin | September 6, 2008
doing a search for electric cars I come up with tons of conversions available as well as some very nice production models coming out soon - both reasonably priced and also high zoot. So much less maintenance, cheaper too run, and no emitions at all. If youre keeping within a hundred miles of home, as everyone almost always does, why not go electric?
And what happened to the ethenol fuel cell? simpler than hydrogen in every way.
I feel it’s a marketing hype - misdirection from what is really “green” and not just “greener”
A hybrid is just a car with good gas mileage.
I’ll find you an electric car that suits everything you want -try me!

Run Your Car on Water.is it a Scam? Read This.find Out the Truth for Your Self
By admin | September 4, 2008
The world is a mess.Priceses are going up.The environment is going worse.Species are dying and in the middle of it all is us hurting over the cost at the gas pump.
Well now you can do something about it.Hydrogen cars are very much in the news these days.Now you can become a part of the global trend for saving money while helping the environment.
CAN WATER REALLY POWER A CAR?
I MEAN IS THIS FOR REAL
The answer is YES.Water is a supplement of gasoline or diesel fuel that increases mileage tremendously.www.cbrecommended.com/autos/cars.html will show you how to use a little electricity out of your car battery to separate water into a gas called (HHO).
HHO means 2 parts hydrogen and 1 part oxygen.HHO is also called BROWN’S gas or hydroxy and the end of the gas is just water that burns beautifully.The technology is already running in many cars
www.cbrecommended.com/autos/cars.html
HHO gas is 3 times more potent than gasoline and that is faster growing trend for bossting mileage and performance.This works in any weather and road conditions.
This small simple hydrogen generator system is easy to install into your engine and can improve your engine mileage between 15-50%.
Burning water for gas is a proven technology that is guaranteed to lower fuel costs,increase gas mileage and help the environment.The only problem is until recently this technology was too expensive for the average car owner to implement.You can easily spend over $2000 to have a professional complete the conversion for you.
www.cbrecommended.com/autos/cars.html
But recently there are corp of reasonable priced conversion -kit guides that provide simple step by step instructions on how to convert it by your self.
These guides use easy to find ,low cost materials and don’t require technical experience.We looked over the market today to find the best guides available.
From our point of view we figure out that this technology actually works and if you pick the right guide you’ll be up and running with in few hours and for less than $100.
WATER CAR PRO
***— Still the best single water conversion guide on the market in 2008.This is the easiest guide we came across.It will take just half a day to source the parts and get fully installed.This guide assumes that you have no knoweldge about cars at all.Their technical support is one of the best.
This conversion guide offers an 8 week money back guarantee.So there is nothing to lose especially that this device can be easily removed as it can be easily installed.
This device works on all kind of cars,trucks,vans and SUV.It works with any gas or diesel powered cars.Even it’s possible to convert a fuel injected car.They are running an advertising for a limited time for $47.Take a look for your self because i don’t know when they will go back to the regualer price of $197.
WATER 4 GAS
Our second pick uses the same HHO conversion techniques as out top pick and again we were impressed by the set up cost and the fast support money back guarantee.This guide also includes two bounses:
1.How to get the IRS to pay for your up grade?
2.How to make $300 installing the system for others,arguably worth the cost for the guide on their own?
All in all it is a great package which means you can be enjoying massive fuel saving for very little very quickly.The only thing we found is the directions were a little hard to follow .There price is a little bit more then our first pick and that’s how this business is.There conversion -kit cost $97 down from $297 for a short time and it will and i mean i will go up again.
RUN YOUR CAR WITH WATER
We found run your car with water to be very easy to understand .Included is simple step by step instruction and pictures to pack it up and help you understand the whole process.The equipment and tools really works and the set up cost is affordable will under $100.
There conversion -kit cost $50 down form $297 also for a short period of time.So grab yours today.
The only reason the priceses are down is because there is a promotion period for these conversion-kit guides and once it’s over the price will go back to normal.
All of these conversion-kits will cut fuel costs by up to 60%,clean up your engine deadly CO2 emission and enhance your engine power all with WATER.

Water is the solution to our energy problems.
Petrol dependency of the US is a National Security Hazard.
The immediate solution to the energy crisis and smog problems is this DEVICE
