PLS HELP!!
Balance this equation: __H2+ 2 O2---> 2 H2O

 2H₂   +   O₂  →   2H₂O

Explanation:

The expression of the equation is given as:

              _H₂   +   2O₂  →   2H₂O

Now for expression above,

                           Reactants                                          Products

H                              2                                                            4

O                              4                                                           2

to balance the equation, we use 2 moles of hydrogen gas and 1 mole of oxygen gas;

           2H₂   +   O₂  →   2H₂O

i think 4.44 moles

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
