Make a simple sketch of the shape of the main part of the periodic table, as shown.
(a) Ignoring H and He, write a single straight arrow from the element with the smallest bonding atomic radius to the element with the largest.
(b) Ignoring H and He, write a single straight arrow from the element with the smallest first ionization energy to the element with the largest.
(c) What significant observation can you make from the arrows you drew in parts (a) and (b)?
Question- The dissociation constants of ascorbic acid are: pKa1=4.1, pKa2=11.7. Write out the main structures of ascorbic acid at pH=1, pH=6, and pH=14, respectively.
What mass of silver chloride would be formed from mixing 250 mL of 0.240 M MgCl2 solution with 200 mL of 0.380 M AgNO3 solution? AgCl FWT = 143.32 g/mol
Describe the reaction and mechanism of solvolysis reaction of tert-butyl bromide in ethanol.
determine number of moles of oxygen molecules are in the cylinder if the volume of the cylinder is 5500 ml and the
Combustion reaction, A fuel has the following weight percentage composition, C = 52%, H = 11%, S = 0%, O = 9%, moisture = 13%, Ash = 15%
You perform a mass spectral analysis and determine that Sample A has a base peak at m/e = 72 as well as Sample B has a base peak at m/e = 58. For alkyl amines such as A and B, base peaks result from cleavage alpha to the N atom. Allot structures t..
B)if water is added to 150ml of a 1.2M KCL solutionuntil the volume is 150 ml what is the new molarity?
Evaluate reversibility of a process where an ideal monoatomic gas is first slowly compressed 10-fold by a gradually increasing external pressure (gas remains in thermal equilibrium with the surroundings) and then the pressure is rapidly removed al..
What conclusions can you draw concerning structures of species containing the same number of atoms and the same number of valence electrons?
Draw a Lewis structure that obeys the octet rule for each of the following anions. (Assign lone pairs, radical electrons, and atomic charges where appropriate.)
26.0 grams of an unknown sugar was dissolved in water and the final volume of the solution was brought up to 1.00 L. The osmotic pressure of this solution was determined to be 3.53 atm at 25°C. Which of the sugars below was most likely the unknown..
Define by drawing the key resonance contributor of one or both of the conjugate bases in question, including curved arrows showing how you formed the contributor.
