Question- What is the osmotic pressure of a 284 mL fructose (sugar) solution containing 102.33 g fructose (C6H12O6) at 25 oC [density of the solution = 1.137 g mL-1]? A. 63.0 atm B. 13.9 atm C. 43.0 atm D. 48.9 atm E. 2.00 atm
I have the answer, need an explanation please!
Explain what would you expect to be the major product of nitration of 2-methylacetanilide. Define reasoning with reference to the nitration of 4-methylacetanilide.
the standard free energy change for the reaction of nitrogen gas with hydrogen gas to produce ammonia is -32.9 kj.
Identify the longest, shortest, strongest and weakest bond out of the following: a triple bond, double bond, a single bond carbon attached to methyl groupCH3- CH2- CH- CH3 | CH3 and a single bond between a doubly bonded carbon attached to methyl g..
10.0ml of 0.10M Pb(NO3)2 is mixed with 10.0ml NaCl. After equilibrium is attained, it is determined that the concentration of Cl- in solution is 0.0218M. Calculate the Ksp of PbCl2.
Calculate the standard cell potential for each of the following cells then write the overall reaction. (These rxns are given in reduction order for each half-cell.)
how long it will take the same ammount of gaseous I2 to effuse from the same container under identical conditions.
the uncatalyzed decomposition of hydrogen peroxoide is first order with an activation energy of 75.3 kj/mol and a half life of 6 hrs at 40 degrees celcius.
At 800 k, Kc for the following equalibrium is 4.2 x 10 ^-3. 2HgO(s) 2Hg(l) + O2(g), suppose 96.5 g of mercury(ll) oxide is placed in a sealed 3.50 vessel at 800 k. What is the partial pressure of oxygen gas at equalibrium
What mass of carbon dioxide is produced from the complete combustion of 6.20×10?3 of methane: CH4+ 202 Yields CO2+ 2H2O
It is quickly degraded in the atmosphere though reaction with OH• and O3 to form non volatile species which then form particles. These latter ones are responsible for the haze.
