QUESTION 17 is 4 POINTS 1) Name the compound whose formula is a) CaBr2 b) Aucis c) (NH)PO. d) Cas(PO3)2 2) What is molecular geometry of the PH molecule? a) linear b) bent c) tetrahedral d) trigonal pyramidal 3) Which compound contains a polar covalent bond? a HF b) NaF c) F d) H 4 Which of the following reactions can be classified as decomposition? a) Cuco (s)-+ Cuo(s) coz(g) b) 4Fe(s) 302(g) 2Fea0,(s) d) NaOH (aq)+ HCI (aq)- NaCl(aq)+ Hzon 5) Determine the limiting reactant and the grams of product obtained if 50 g of each reactant i present initially.Explanation / Answer
1) Calcium Bromide, Gold (III) chloride, Ammonium phosphate, Calcium phosphite
2) Molecular geometry of PH3 is triangular pyramidal
3) Only HF has a polar covalent bond. As HF molecules undergo hydrogen bonding.
4) Only reaction 1 i.e. CuCO3 ===> CuO + CO2 is decomposition as single molecule is breaking down into 2 molecules.
