Yes.
Except that the word is equals, not eqauls.
4H2 + N2 --> 2H4N+
Fe3O4 is the mineral magnetite, with aproper chemical name of Fe(II, III) oxide. it exhibits ferrimagnetism. It has iron atoms as FeII and FeIII. An old way of writing it was FeO.Fe2O3 The balanced equation for production from the elements is :- 3Fe + 2O2 -> Fe3O4 Commercially it is made by for example redung Fe2O3 with CO 3Fe2O3 + CO = 2Fe3O4 +CO2
The 4 in 4H2 stand for "4" molecules in that equation, unless specified as being moles.
NaBH4 + 2H2O -> NaBO2 + 4H2 [1] DeltaG(298K)= -299 kJ/mol BH4 DeltaH(298K)= -231 kJ/mol BH4 (10.8 mass% H) NaBH4 + 4H2O -> NaB(OH)4 + 4H2 [2] DeltaG (298K)= -315 kJ/mol BH4 DeltaH = -247 kJ/mol BH4 (7.28 mass% H) NaBH4 + 6H2O -> NaB(OH)4.2H2O [3] DeltaG = -319kJ/mol BH4 DeltaH = -213 kJ/mol BH4 (5.48 mass% H) *Hydrolysis in Eq.[1] is not the most favorable reaction!

O2 +4H2--> 2H2O
2Ag20 --> 4Ag + 02 Fe304 + 4H2 --> 4H20 + CuCl2
C6H12 + Cl2 --> C6H12Cl2
2C+2H4=2CH4(instead of 'equal to' use 'arrow sign').
H2 is the molecule of two Hydrogen atoms. The 4 means that there are 4 of the molecules. ■
The meaning of 4 H2 is four molecules of hydrogen.
No. Take the microbial hydrogen mechanism as an example:4H2 + CO2 --> CH4 + 2H2O5 moles of reactants on the left converts to 3 moles of products on the right. The total number of moles of each type of atom does balance however.
