What is the standard enthalpy of formation for butane?
the standard enthalpy change of vaporization DHov is the enthalpy change when one mole of a substance is transformed into a gas enthalpy change is the term we use to describe the energy exchange that occurs with the surroundings at a constant temperature and pressure so to work it out, use the formula DH = cmDT DH - the enthalpy change c - the specific heat capacity of butanol (kJ kg-1 °C-1) m - the mass of butanol heated (kg) DT - the change in temperature of the butanol (°C) so there is no general enthalpy change of butanol, it depends on the factors above. the specific heat capacity of butanol, the mass of butanol heated, and the change in temperature of the butanol should be given to you in order to work the enthalpy change of vaporization of butanol if there is a rise in temperature, the reaction is exothermic and if there is a drop in temperature the reaction is endothermic. exothermic reactions have a negative enthalpy change, and therefore endothermic reactions have a positive enthalpy change. hope it helped (:
Is ethanol or butanol a better fuel for a camp stove - Why?
Both of them will work. I'm going with ethanol because you can go to any hardware store in America and buy a can of "denatured alcohol," which is ethanol mixed with something to make it undrinkable (usually methanol, but they can use a lot of things, like Bitrex or gasoline). Butanol is harder to get. Additionally, it is likely that butanol will not burn clean. The extra carbon bonds require more oxygen to fully combust. You will probably end up with a lot of soot on your kettle and in your backpack, not to mention a nice chemical smell at your campsite.
How many molecules are present in a sample of this compound that contains 3.10 moles of 3 methyl 2 butanol?
To determine the number of molecules in a sample of a compound, you can use Avogadro's number, which is 6.022 x 10^23 molecules/mole. In this case, if you have 3.10 moles of 3-methyl-2-butanol, you would multiply the moles by Avogadro's number to find the number of molecules in the sample.
What is the use of decene?
Decene is an alkene which is a hydrocarbon made from crude oil but with a double bond between the two carbon atoms. To make use of any alkenes which in this case is decene you could turn it into a polymer (which is a plastic). to do this you go through a process called polymerisation. At the start of polymerisation first you have your alkene which is called a monomer in this case it would be decene and you would have lots of them, then after polymerisation it would turn into polydecene- a type of plastic this plastic would be a type of use hope it answers the question!!
What test distinguishes between alkene and alcohol?
Baeyer's test for unsaturation using KMnO4 . if the sol'n retains the purple color of the reagent , then it is an alkane. if the color disappears with formation of brown precipitate ,it indicates presence of unsaturated HC
What is the Use of everyday life in bromine?
it can be used to see if the hydrocarbon you have just cracked is an alkane or an alkene (it with turn orange to colourless if it is an alkene)
How many times does the bible use the word prepare?
You could count this up. Prepare ye the way of the Lord is one of the more memorable uses of the word prepare.

What reagents would you use for the synthesis of 1-chlorobutane from 1-butanol?
anhydrous Zinc chloride and aq.HCl or CaCl2 and HCl.
How many grams of water are formed when 5.00g of butanol combust with excess oxygen?
To determine the number of grams of water formed, we need to calculate the moles of butanol (C4H9OH) and then use the balanced chemical equation to find the moles of water produced in the combustion reaction. From there, we convert moles of water to grams. The balanced equation for the combustion of butanol is C4H9OH + 6O2 → 4CO2 + 5H2O.
How do you use word prepare?
