How many Liters of Carbon Dioxide gas (CO2) would be
produced if 6.4 L of methane (CH4) would fully react in the
following equation:
CH(g) + 2 02(g) I-> CO2(g) + 2 H2O(g)

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Ijust took the quiz. their is no coefficient needed. : )

Hi + naoh -> h2o + nal
