For each of the following unbalanced reactions, sup- pose exactly 5.00 g of each reactant is taken. Deter-
mine which reactant is limiting, and also determine
what mass of the excess reagent will remain after the
limiting reactant is consumed.
a. Na, B,0,(s) + H2SO.(aq) + H2O(l) →
H_BO3(s) + Na2SO.(aq)
b. CaCz(s) + H2O(l) + Ca(OH)2(s) + C2Hz(8)
c. NaCl(s) + H2SO.(I) → HCI(3) + Na 50 (5)
d. SiO,(s) + C(s) + Si(l) + CO(3)

How do you convert 4 mmol of bromobenzene to ml?

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
