“There is also a pre-Sanskrit type language (making it very old) engraved on some of the objects including on the underside of the black pyramid where there are also markings which appear to map out the stars of the Orion constellation, which the pyramids at Giza also map. The 4 pre-S...
The concentration of H+ in 1 M H2SO4 is (greater/less) than in 1 M HNO3 because H2SO4 has (zero/one/two) ionizable hydrogens per mole whereas HN Classify each of the following as a strong acid, weak acid, strong base, or weak base in aqueous solution. a. HNO...
