Write the balanced total ionic equation and the net ionic equation (including phase labels) for the reaction between HC2H3O2(aq) and NH3(aq).
Carbon emits photons at 745 nm when exposed to blackbody radiation. How much energy would be obtained if 44 g of carbon were irradiated?
An aqueous solution of Na2CO3 has a pH of 10.00. The CO3-2 (carbonate anion) is the conjugate base of its conjugate acid, HCO3- (bicarbonate anion). Write the net ionic equation for the reaction which shows why the solution has a basic pH.
And what is difference between single electrode and full supercapacitor device results?
Discuss the merits and disadvantages of dispensing a drug as a reacemic mixture or as a single enantiomer.
Calculate the heat given off when 177 g of copper cools from 155.0 Celsius to 23.0 Celsius. The specific heat capacity of copper is .385 J/g C
What are the advantages of the Stock system of nomenclature over the former one?
A 4.10 g nugget of pure gold absorbed 287 J of heat. The initial temperature was 24.0°C. What was the final temperature?
A carbon-hydrogen-oxygen containing compound yields 1.029 g CO2 and 0.198 g H2O in a combustion analysis( note that this means O2 was added the overall reaction) what is the empirical formula? if the Molar mass is 138.16 what is the molecular form..
The Rice-Herzfeld mechanism for the thermal decomposition of acetaldehyde (CH3CO) is the following below (10 points) (1) CH3CHO ---> CH3' + CHO' (k1) (2) CH3' + CH3CHO ---> CH4 + CH2CHO' (k2) (3) CH2CHO' --->CO + CH3' (k3) (4) CH3' + CH3' --->C2H6..
Aspirin (C9H8O4) is produced through the following reaction of salicylic acid (C7H6O3) and acetic anhydride (C4H6O3). C7H6O3(s) + C4H6O3-> C9H8O4(s) + HC2H3O2
If the gas is at 23C and 1.0 atm, what mass of helium is in the blimp? The Goodyear blimps, which frequently fly over sporting events, hold approximately 1.85×105 ft^3 of helium.
