1. the marcellus formation, which is famous for providing gas when fracked, is a shale formation in the eastern us that is interpreted to have formed in deep water. in contrast, the queestone formation of ontario, canada, is a shale formation that is interpreted to have formed in shallow, almost supratidal waters. how do geologists know that one shale formed in deep water and the other in shallow water? what features can be seen in the rock suggesting the environment of deposition?

2.how would you recognize an ancient alluvial fan deposit in the geologic record

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
