How is mitotic metaphase similar to metaphase I of meiosis I and how are they different from each other?
The dissociation energy for N2 is 9.76 eV. Light of energy21.23 eV cause N2 to emit photoelectrons, the most energetic of which have kinetic energy of 5.42 eV. The energy required to ionize a nitrogen atom is 14.53 eV. Approximate the dissociation..
The reaction: 2 HI → H2 + I2, is second order and the rate constant at 800 K is 9.70 × 10-2 M-1 s-1. How long will it take for 8.00 × 10-2 mol/L of HI to decrease to one-fourth of its initial concentration.
The following question refers to a solution that contains 1.79 M hydrofluric acid, HF (Ka = 7.2 x 10^-2) and 3.00 M hydrocyanic acid, HCN (Ka = 6.2 x 10^-10). What is the pH of this mixture of weak acids
The crude copper that is subjected to electrorefining contains tellurium as an impurity. The standard reduction potential between tellurium and its lowest common oxidation state, Te^4+, is Te^4+(aq)+4e-=> Te(s) E°red= 0.57V
Cattell was interested in discovering the fundamental structure of personality. He utilized a statistical procedure named factor analysis.
For one line of the hydrogen spectrum is .4118 x 10-4 cm. Use this value in the Rydberg equation to calculate the RH value using n1 = 2, and n2 = 3.
Problem- If 25 mL of 0.10 M NaOH is added to 35 mL of 0.20 M HC2H3O2, what is the pH of the resulting solution at 25°C? Ka for HC2H3O2 is 1.8 x 10-5 at 25°C.
Question- Why does it take 10 water molecules to break down an oligosaccharide that contains 10 glucose units
What are the equilibrium concentrations of Ca2+ and CrO42- in a saturated solution of CaCrO4?
In an experiment, 0.40 mol H2 and 0.40 mol I2 are mixed in a 1.0- Liter container, and the reaction forms HI. If Kc = 49 for this reaction, what is the equilibrium concentration of HI
assume that due to dwindling supplies of crude oil and natural gasthe us embarks on a plan to implement the hydrogen
Consider the following reaction involving bromophemol blue (BPB) and OH- : HBPB(aq) + OH-(aq) = BPB-(aq) + H2O(l). The concentration of BPB can be monitored by following the absorption of this species and using Beer-Lambert law. In this law, the ab..
