Problem- Calculate the heat of reaction for the reaction of carbon suboxide with water to form malonic acid (HO2CCH2CO2H). Note- Each end of malonic acid has a carbon double bonded to oxygen and bonded to a hydroxide.
I am in urgent need of solution of above problem with complete explanation
Require to dissolve CaCl2 in water to make a mixture that is 33.0% calcium chloride by mass. If the total mass of the mixture is 942.4 g, explain what masses of CaCl2 as well as water should be used
how many moles of sodium hypobromite rm nabro should be added to 1.00 rm l of 5.0times10-2 m hypobromous acid rm hbro
What are the percentages of each molecular ion? (List to nearest 1% in order of increasing mass separated by commas, e.g. 55,45.)
Pheromones are compounds secreted by the females of many insect species to attract males. One of these compounds contains 80.78 percent C, 13.56 percent H, and 5.66 percent O. A solution of 1.00 g of this pheromone in 8.50 g of benzene freezes at ..
Offer the structures of the expected main organic products(s) generated upon completion of the subsequent reaction scheme.
Question- Explain any differences in regio- and/or stereochemistry of the proposed products. Including a mechanism as part of your answer, with notes clearly indicating any intermediates you believe to be present during these conversions may be he..
The molar heat capacity of ethane is represented in the temperature range 298 k to 400 k by the empirical expression C(p,m)/(J K-1 Mol-1) = 14.73 + 0.1272 (T/K). Calculate the standard enthalpy of formation of ethane at 350 K from its value at 298..
Tris base (pka =8.1 ; ka = 8.32 e-9) was dissolved in 0.5l of water to give the final concentration of 1 M. a.) find pH of the obtained solution. b.) how much does the pH change after addition of 1 ml of 10N HCl?
Consider 30.00 ml of a 0.1200M solution of H2SO4. What is the ph of the above solution
A solution is exposed to air where the partial pressure of N2 is 0.80 atm, and the concentration of N2 in solution is 6.0x10-4 M. What would be the concentration of N2 in solution if the partial pressure is lowered to 0.40 atm
At a constant pressure of 97.0 atm, calculate the work done by the gas when the volume decreases from 87.0 L to 19.0 L. (make sure the sign and units are correct)
