4 + 2 = 6, as usual.
Vinegar is acetic acid or CH3COOH and there are totally 8 atoms (2 carbons, 2 oxygens and 4 hydrogens) in one molecule of vinegar.
3?
There are 3 atoms in a carbon dioxide molecule: 1 carbon atom and 2 oxygen atoms.
To determine the number of atoms in the compound ammonium carbonate, (NH4)2CO3, we must be careful to remember that the little numbers (subscripts) are multipliers. Inside the parentheses, we have 1 nitrogen and 4 hydrogens, a total of 5, but the parentheses have a two multiplier, so we have two sets of NH4, a total of 10 atoms. In the carbonate, there is 1 carbon and 3 oxygens, bringing our total number of atoms to 14.
Dihydrogen pentaoxide would mean 2 hydrogens and 5 oxygens, or H2O5. This would be an exceedingly unstable molecule, since two hydrogen atoms normally combine with only one oxygen atom, not five.
CO2 and H2O has 1 carbon, 2 hydrogens and 3 oxygens.
Two. The equation means two water molecules, H20. Thus you have 4 hydrogens and 2 oxygens.
Vinegar is acetic acid or CH3COOH and there are totally 8 atoms (2 carbons, 2 oxygens and 4 hydrogens) in one molecule of vinegar.
2 Carbon atoms, 4 Hydrogen atoms and 2 Oxygen atoms. So, a total of 8 atoms.
3?
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.

There are 3 atoms in a carbon dioxide molecule: 1 carbon atom and 2 oxygen atoms.
There are two hydrogens in H2SO4. So there are six hydrogens in 3H2SO4.
There is no limiting reactant in that equation, it's balanced. Four hydrogens on the left, 4 on the right, 2 oxygens on the left, 2 oxygens on the right. If it was 3H2 then it would be oxygen.
The number of hydrogens equals 2x the number of carbon atoms, plus 2 extra hydrogens.
In an alkane, each carbon atom is bonded to 4 hydrogen atoms. So, the number of hydrogens in an alkane can be determined by the formula 2n+2, where n is the number of carbon atoms in the alkane.
