Hydrazine (N2H4) and dinitrogen tetroxide (N2O4) form a self-igniting mixture that has been used as a rocket propellant. The reaction products are N2 and H2O.
(a) Write a balanced chemical equation for this reaction.
(b) What is being oxidized, and what is being reduced?
(c) Which substance serves as the reducing agent and which as the oxidizing agent?
After the resulting reaction was complete, back titration required 10.40 mL of 0.1212 M NaOH. Assuming that the tablet contained only calcium carbonate and an inert binder calculate the mass of calcium carbonate and mass percent of calcium carbona..
A compound contain 60.87% carbon, 4.38% hydrogen, and 34.75% oxygen then determine its empirical formula?
Calculate the standard reaction enthalpy for the following reaction. N2H4(l) + H2(g) -----> 2NH3(g) Given: N2H4(l) + O2(g) -------> N2 (g) + 2H2O(g)
What would you expect to see in a reaction between salicyclic acid and ferric chloride. I would also like to know why.
In a separate experiment, an empty flask is weighed, 35.3 cm3 of the lubricating oil is poured into the flask and the flask is reweighed. If the scale reading was 124.8 g in the first weighing, what would it be in the second weighing
Wwrite a research paper "A Masked Two-Coordinate Cobalt (I) Complex That Activates C-F Bonds"Discuss how a bulky β-diketiminate ligand on cobalt (I) undergoes a novel isomerization.It must be five to six pgs length.
The answer is E. I'm confused doing the step by step procedure. I'm not sure why we use [H+]=10^-pH and Ka*Kb=Kw. What mass of potassium fluoride must be added to 500.0 mL of water to give a solution with pH = 8.07? [Ka(HF) = 7.1 × 10-4]
1. Propose an extension experiment that would allow you to determine the concentration of ethanol in alcoholic beverages using the information collected from this lab. In the lab, we determined the Keq for the equation CH3CH2OH + NAD+ ---> CH3CHO + N..
Problem- An electron in a hydrogen atom has orbital quantum numbers n = 2 and l = 1. Calculate the energy E, and give the degeneracy of this electron state. If you could define and illustrate the math that would be great
