Explore 2 factors involving the fuels methane, ethanol, hexane and compare the results. this is for chemistry.
Darren G questioned:
This is for IB chemistry. i have a preparation lab where i have to explore these three fuels and talk about their efficiency, imapct to background or any additional factors of the three fuels.
efficiency = electrical energy out / total energy in x 100%. ?
wateva questioned:
The efficiency of a potential rank is a rate of its effectiveness in
converting fuel into electrical energy. In this case we can define
efficiency = electrical energy out / total energy in x 100%
If a potential rank has an electrical potential productivity of 1150 MW and an
efficiency of 32%, how much energy is converted to forms additional than
electrical energy each day?
SHOW your effective and give your pledge to an apt number of significant figures.
Note: some of this ‘waste’ energy is sometimes used for additional helpful
purposes, e.g. to heat buildings or greenhouses.
How many equivalents are in 3.5 moles of chloride ions?
ME questioned:
How many Carbon atoms are bestow in 56.0 grams of carbon dioxide?
The fuel efficiency of an automobile is 34.5 mi/gal. Convert this quantity into units of km/L. (1 mi = 5280 ft) (2.54 cm = 1 in) (3.78 L = 1 gal)
Help I just don’t be with you this material.
Microbial Fuel Cells?
a_chamarthy questioned:
What are some current top tribulations with the MIcrobial Fuel Cell (MFC)…….
What chat would mushroom metabolism have on the efficiency of the fuel cell?
How many joules of energy is required to split one mole of H2O into one mole of H2 and 1/2 mole of 02?
Matthias O questioned:
So I want to now the amount of energy, in joules to tear distilled fill up into hydrogen and oxygen per mole at ordinary like and pressure. Also if you may maybe clarify it’s efficiency factor, that would be very caring. I want this so I can figure out the efficiency of a hydrogen fuel cell.
Chem Question in regards to air fuel ratios.interesting read below?
noshkay questioned:
An automobile engine requires a carburater or fuel injector to mix fuel with air. The fuel and the air must bemixed in a fastidious ratio to acheive maximum efficiency in the combustion of fuel . What force take place if the fuel and air mixture is too rich ( if here is too much fuel ?) delight and be grateful you :]
as in what may maybe be bent etc .
Chemistry Conversion problem?
brock_1011 questioned:
The Honda Insight, a hybrid gripping vehicle, has an EPA gas mileage rating of 57mi/gal in the city.
How many kilometers can the Insight travel on the amount of gasoline that would fit in a soda pop can? The number of a soda pop can is 355 .
chemistry problem please help?
oakleyku questioned:
The Toyota Prius, a hybrid gripping vehicle, has an EPA gas mileage rating of 52 miles per gallon in the city.
How many kilometers can the Prius travel on 13 liters of gasoline?
Express your pledge using two significant figures.
How much energy does it take to separate hydrogen and oxygen from H2O?
StarMan questioned:
High and mighty it’s a 100% efficient logic (probably electrolytically).
Also, I’m wondering how this would equate to the energy you get from burning the hydrogen?
This is not investigate; I’m just wondering the value of hydrogen as a potential fuel before efficiency is factored in.
Compare the use of enthanol versus gasoline as a fuel, from a the standpoint of efficiency?
Shanna questioned:
The gears of gasoline have the same general formula sa paraffin.
What are some Chemical ways of saving Energy?
Steven T questioned:
Hi I need help on my chemistry hw but I cant find anything… I googled my topic but it doesn’t help much. Ex: One way is Hybrid car which uses a combustion engine, electricty, or battery.
Why does the U.S. use propane gas for grilling food instead of butane gas?
Bone idle Cat questioned:
As far as I know, some additional countries use butane gas as a substitution for. What are the main differences? The cost? The fuel efficiency? protection?
Energy efficiency?
janelle m questioned:
How does the energy efficiency of fuel cells equate with the energy of additional methods of producing electricity?
What energy transfers would be made in a battery producing plant?
Dead questioned:
for hybrid cars
How do conventional and alternative sources of energy with respect to efficiency and environ. impact compare?
Gary King questioned:
I am looking for in rank to equate conventional and uncommon
sources of energy with accept to efficiency and environmental impacts
(e.g. burning fossil fuels, solar energy, and nuclear fission.)
Delight reside in as much chemistry as possible, with calculations,
diagrams, and equations.

Improving Efficiency of PEM fuel cells?
a_chamarthy questioned:
Ciao all,
I’m doing a knowledge project related to humanizing efficiency of proton chat membrane (PEM) fuel cells / sinking expenditure of manufacturing PEM fuel cells.
I’m specifically attracted in developing a more efficient vehicle as opposed to platinum.
I would be thankful for it if you may maybe give with a few caring websites / top me in the right management.
Thankfulness alot.

Improving Efficiency of PEM fuel cell catalyst?
a_chamarthy questioned:
Ciao all,
I’m doing a knowledge project related to humanizing efficiency of proton chat membrane (PEM) fuel cells / sinking expenditure of manufacturing PEM fuel cells.
I’m specifically attracted in developing a more efficient vehicle as opposed to platinum. I have a PEM fuel cell; I got it as part of a fuel cell car kit.
Now, I’m not keen to waste much cash. I have a multimeter – what I’m wondering is what kind of experiment may maybe I top (with some household-hold bits and pieces or some moderately low-cost ones at some electronics store) to boost the efficiency of the current platinum vehicle?
Thankfulness alot.
