A pi bond (VB theory) or a double bond (VSEPR theory) does not affect the geometry of a molecule.
a) What is hybridization of valence shell orbitals are predicted on sulphur or carbon in SO2 and CO2? (Hint-draw the lewis dot structure of each first, following the octet rule.)
b)What geometry do you predict for SO2 and CO2
You are asked to calculate the concentration of a NaCl (in water) solution in several ways and are given the following information: 30 g NaCl, 300 mL solution, Molecular weight of NaCl = 58.44 g/mole
Discuss the physical changes that indicate the occurrence of a reaction. Discuss the use of the solubility tables to help identify a product formed in a chemical reaction.
If I have 2.5g of Na2CO3, how much distilled water would I have to mix it with to obtain a 1.0M solution of sodium carbonate. If I have 2.5g of NaHCO3, how much distilled water would I have to mix it with to obtain a 1.0M solution of sodium carbonate..
A silicon water is etched in a Cl2 plasma. A mass flow controller (used to meter the gas flow fed to the reactor) shows a reading of 100 sccm (sccm=standard cm3 per min; standard conditions are 273 K and 1 atm). The etching reactor operates at 100..
A 245 mL stock solution contains 2.3 M Ca(CN)2. When 100 mL of the stock solution is diluted to 120 mL, how many moles of CN- ions will be contained in the dilute solution?
Predict the magnetic susceptibilities (para- or diamagnetic) and determine the number of unpaired electrons of each of the following complexes (consider C2O42- and H2O as strong field ligands which cause a large splitting of the d-orbitals).
Describe the chemistry involved in the current indstrial preparation of adipic acid, specifically listing the major by-product
Problem- Describe the synthesis of 2-hexanone from acetylene and any necessary organic and inorganic reagents or describe the steps involved in the synthesis of 2-hexanone.
Calculate the molarity of a hydrochloric acid solution that is 18.25% HCl by mass and has a density of 1.20 g/mL.
Presume that you found that the average volume of water required to fill the graduated cylinder to the 8.00mL mark was 7.95mL. Explain what is the percent error
Draw all products of the reactions of 4-Chloro-2-methylpentane with NaCN and AgCN. Identify the reaction mechanisms and draw resonance structures
Explain how many possible trisubstituted derivatives C6H3X2Y can be obtained from the para disubstituted benzene C6H4X2. Overlook directive effects of the substituents X and suppose that all positions on the ring are accessible to the reagent Y+.
