One molecule has only one C atom.So 0.56mol has 0.56mol of C atoms
Methane is an elementary organic compound having the molecular formula of CH4. Methane is composed of carbon (C) and hydrogen (H) atoms. The molecular weight of CH4 is 16. 01 grams per mole.
CH4's melting point is -182 C. In the context of the usual type of question about melting points, CH4 has a very low melting point because the attractions between CH4 molecules are very weak.
First you must find the no. on moles in 1.6g of ch4. ie. ch4=C+h4=12+(1.008x4)=16.032 or 16 approx moles=1.6/16=0.1 No. of electrons=no. atoms ie. no of moles x 6.022x10^23 =0.1x 6.022x10^23 =>6.022 x 10^22(approx)
C ( carbon ) = 12.01 grams/moleH ( hydrogen ) = 1.008 grams/mole * 4------------------------------------------------------------add= 16.042 grams/mole===============
7.11 grams glucose (1 mole C6H12O6/180.156 grams)(6 mole C/1 mole C6H12O6)(6.022 X 10^23/1 mole C) = 1.43 X 10^23 atoms of carbon ------------------------------------------
Moles of methane. No half molecules, I think! 2.50 moles methane (1 mole C/1 mole CH4)(6.022 X 1023/1 mole C) = 1.51 X 1024 molecules of carbon --------------------------------------------
There are 0.75 moles in it.You have to devide 12 by molecular mass
CH4 --> CO2 is a 1 to 1 reaction (C-balanced) when burning with oxygen. So 1 mole CH4 --> 1 mole CO2 So 1 Litere CH4 --> 1 Liter CO2 So 16 grams CH4 --> 44 grams CO2
c + 2h2 ---> CH4
Methane is an elementary organic compound having the molecular formula of CH4. Methane is composed of carbon (C) and hydrogen (H) atoms. The molecular weight of CH4 is 16. 01 grams per mole.
Since 12 g C is 1.0 mole C there are 6.02*10+23 atoms in (each) mole; that's the definition of a mole
There are four bonds. All are C-H bonds
It is propane
CH4's melting point is -182 C. In the context of the usual type of question about melting points, CH4 has a very low melting point because the attractions between CH4 molecules are very weak.
Answer 1CH4
C8h18 + 3h2 ---> ch4 + 2c2h6 + c3h8 All these C's and H's are supposed to be capitalized. -- Some computer keeps changing them.
