Can you explain to me the role of redox reactions in photosynthesis and what type of reaction is cellular respiration?
What volume of 0.160 M of Li2S solution is required to completely react with 125 mL of 0.160 M of Co(NO3)2
Compute the value of ΔH ° if the combustion products are CO2 (g) and H2O (g). it isgiven that: CO 2 (g) = ΔHf ° - 393.5 kJmol-1; H 2 O (l) = ΔHf ° -285.8 kJmol-1; H 2 O (g) = ΔHf ° -241.8 kJmol -1.
A water sample is suspected to be contaminated by iron (III) ions. How could you determine if the sample is really contaminated
Given that K for the following reaction equals 2.2. Calculate K for the reverse reaction. SO2(g)+1/2O2(g) SO3(g). Please explain the steps so I can understand.
List infrared peaks which are found for methyl m-nitrobenzoate which would not be found in the infrared spectrum of methyl benzoate. List functional group/bond as well as position.
These are characteristics of the titration curve for 25.0 mL of 0.400 M NH3(aq) titrated with 0.335 M HI(aq). (For NH3, Kb = 1.8x10-5.) (1a) The initial pH : (1b) The volume of HI(aq) required to reach the equivalence point
Consider the following data. 2 Ca(s) + O2(g) 2 CaO(s) H = -1270.2 kJ C(s) + O2(g) CO2(g) H = -393.5 kJ CaO(s) + CO2(g) CaCO3(s) H = -178.3 kJ Use Hess's law to calculate H for the reaction below.
How would the absorbance of the standard solution have been affected if 0.00050 M NaSCN had been used in place of 0.00040 M? if it changes, calculate the new absorbance based on your values.
