Stable Pb isotopes and Rare Earth Elements geochemistry is …

The strong positive correlation between Cd and Ca (r=0.805, p<0.01) points to the retention of this trace element in the carbonate phase of the sediment, which is mainly formed by calcite. The presence of fauna debris along the core seems to indie that calcite enrichment is related to fragments derived from pelagic and benthic organisms.

Reactions of hydrochloric sulfuric nitric acids with metals …

REACTION OF ACIDS WITH METALS General word equation: metal + acid ==> a salt + hydrogen The salt, and its name, depends on the metal and acid used in the reaction and the acid is neutralised in the process. e.g. the grey-silvery solid zinc dissolves in hydrochloric acid with effervescence to evolve hydrogen gas and leave a colourless solution of the salt zinc chloride.

why HNO3 does not react with Al? Chemical Reactions …

2013/9/30· Ans: Al is more reactive metal. Before reaction with HNO 3 it forms an oxide layer of Al₂O₃.This oxide layer does not allow reaction of HNO₃ with Aluminium. Because of this reason Al vessel is used to store HNO₃. HNO3 does''nt react with Al Or any other metal (except manganese and magnesium) because HNO3 is a strong oxidising agent.
