What is ethanol made of?
Ethanol can be distilled from any material which contains complex carbohydrate molecules. Corn is used frequently in the US; sugar cane is used mostly in Brazil. Leftover plant materials such as corn cobs and wood chips can be used, but require more processing before they are ready to be fermented. Switchgrass and potatoes are other materials which are used somewhat.
How many moles of oxygen are necessary to react completely with moles of propane?
The ratio of propane to oxygen is 1:5. So for every mole of propane, 5 moles of oxygen gas are required for the complete combustion of propane.Balanced equation:C3H8 + 5O2 --> 3CO2 + 4H2O
Why do propane and butane gas furnace require 100 percent shut off in the event of pilot outage?
they are highly flammable
All reactions require activation energy?
No. Some reactions such as one material dissolving into another do not require a starting energy.
How are metals separated from ores?
smelting is used for sulfide ores. Iron ores require a blast furnace. aluminum ores require high temperature electrolysis. etc. it varies by type of ore and metal.
Does the melting point of aluminum change with the thickness?
The melting point of any given substance (such as aluminum) has nothing to do with the thickness or shape of the material being melted. It will melt at the same temperature. But it does require more heat in order to heat a thicker piece of aluminum to its melting point.
Does Michigan require gas stations to post notice of ethanol in gasoline?
Yes
What are some of the advantages of installing a propane gas fireplace over a natural gas or wood burning fireplace?
A propane gas stove doesn't require electricity to keep going. It allows you to stay warm even if there's a power outage. Propane stoves don't require the labor of splitting, stacking and carrying in logs. Propane tanks can easily be refilled by your gas company. Finally, propane burning stoves are affordable and there are a lot of models to choose from.

What are the concerns of using ethanol as a fuel?
Ethanol has many considerations as far as its use as an automotive fuel.\: # On the plus side it is a liquid and easily handled in the present transportation and delivery systems. # On the negative side: * Ethanol from food crops removes food from the system * It requires more energy to produce ethanol than the automobile gets out of the ethanol (Crops require fertilization and fertilizers are made using hydrocarbons, ethanol is made by fermaentation, the fermentation products require distillation, the ethanol is a less efficient fuel than gasoline) * Ethanol combustion creates tail pipe emissions of aldehydes and ketones at levels not present in hydrocarbon fuelled autos * There is not enough land to produce enough ethanol fuel while maintaining food production * Ethanol from waste cellulose is not being pursued asa production route
Which of the gas require a 100 percent shut off natural or propane?
Both are highly flammable, so 100% shut off of both natural gas and propane are required in a closed in area- if that is what you are referring to.

Can we make magnet without using magnetic material?
Yes. Electromagnets don't require a magnetic material; they just require a conductor and an electric current.
How many gallons are in 500 pounds?
This depends on the mass of the material being measured. 500 pounds of steel will require fewer gallons than 500 pounds of aluminum.
Does mozzarella cheese have aluminum in it ive heard they put it in so that it will melt well?
Possibly. Some cheese has aluminum added so that it will slice more easily and melt more readily. The FDA does not require that the aluminum be listed as an ingredient.
Do all fungi require organic material for growth?
Yes
