What is the similarity between metal olefin and metal hydrogen bonds?
heat is removed from 200.0 g of water with an initial temperature of 30.0°C? The specific heat of water is 4.184 J/gdeg.
Draw the molecule by placing atoms on the grid and connecting them with bonds. Show the formal charges of all atoms in the correct structure. Include all lone pairs of electrons.
Determine the grams of sodium carbonate required to precipitate magnesium ions from water used in one wash cycle of a washing machine. Notes: 1) Assume the concentration of Mg+2 is 165mg/L 2) Estimate the volume of water used in your wash cycle 3)..
What is the entropy change for the reaction 2H(g) + O2(g)-------- 2H2O(l) at 25 degree and 300 atm
If a sample solution is 5.00% H2O2 by mass and has a density close to 1.0 g/mL, find the approximate molar concentration of the H2O2 in the solution
this solution was added 1.960 grams of KI and 50.00 mL of a 0.00923 M KIO3 solution. The excess I3- was titrated with 50.00 mL of a 0.02000 M Na2S2O3 solution. What was the mass percent of arsenic trichloride in the original sample?
