Following the formula CxH2x-2 where X is the number of carbons in the desired Alkyne, you should get C8H14 (i think.....)
The number of hydrogens equals 2x the number of carbon atoms, plus 2 extra hydrogens.
An alkane with n carbon atoms has 2n + 2 hydrogen atoms.So, 42.
Carbon = 4 valance electronsNitrogen = 5 valance electrons4 + 5 = 9 and 2 valance electrons used for the single bond, 9 - 2 = 73 hydrogens can attach to the carbon and 4 hydrogens can attach to the nitrogen, so.......7 hydrogen atoms would complete this molecule===================================
2H2S + 3O2 --> H2O + 2SO2 Left Side: 4 hydrogens 6 oxygens 2 sulfurs Right Side: 2 hydrogens 5 oxygens 2 sulfurs no it is not balanced. the correct balanced reaction is this... 2H2S + 3O2 --> 2H2O + 2SO2 Left Side (Reactants): 4 hydrogens 6 oxygens 2 sulfulrs Right Side (Products): 4 hydrogens 6 oxygens 2 sulfurs therefore it is balanced. the only mistake you made was not balancing the hydrogens on the right side. if you balanced them then the oxygens would have balanced automatically and you would have been right. you were really close. keep at it.

Four. A terminal carbon in an alkane is bonded to 3 hydrogens and 1 carbon, while a middle carbon is bonded to 2 hydrogens and 2 carbons.
2H2
It is 1/2.
2 Hydrogens and 1 oxygen.
Water molecules are H2O so there are 2 Hydrogens bonded to 1 oxygen.
An alkane with n carbon atoms has 2n + 2 hydrogen atoms.So, 42.
Well, 1 molecule of water is made up of 2 hydrogens and 1 oxygen. And it is not possible to have 1/2 a molecule of water, therefore, you have to have at least 1 complete oxygen in there, not 1/2.
H2O, water.
Ethanol has 2 carbons, one oxygen, and 6 hydrogens.
2 hydrogens 1 oxygen
2 Hydrogens, 1 Oxygen.
