For each pair of covalently bonded atoms, choose the one expected to have the shortest bond length.(A) C-C(B) C?C (A, B)(C) C?O(D) C-O (C, D)bondlengthtitle. gifThe length of a covalent bond depends upon the size of the atoms and the bond order. For each pair of covalently bonded atoms, choose the one expected to have the shortest bond length.(A) P-Cl(B) Si-Cl (A, B)(C) P-I(D) H-I (C, D)bondlengthtitle. gifThe length of a covalent bond depends upon the size of the atoms and the bond order. For each pair of covalently bonded atoms, choose the one expected to have the shortest bond length.(A) Cl-I(B) I-I (A, B)(C) P-Br(D) P-Cl (C, D)

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
