Atomic theory formula for the water molecule (HO), or 16 if one assumes the modern water formula (HO). The flaw in Dalton's theory was corrected in principle in 1811 by Amedeo Avogadro. Avogadro had proposed that equal volumes of any two gases, at equal temperature and pressure, contain equal numbers of molecules (in other words, the mass of a gas's particles does not affect the volume that it occupies). Avogadro's law allowed him to deduce the diatomic nature of numerous gases by studying the volumes at which they reacted. For instance: since two liters of hydrogen will react with just one liter
Same-sex marriage and the family biological inequality between opposite-sex and same-sex couples, an inequality that is raised in American legal circles in light of the Equal Protection Clause of the 14th Amendment to the United States Constitution. In 1996, Congress passed the Defense of Marriage Act that defines marriage in Federal law as "a legal union between one man and one woman as husband and wife".
