A five quark combination called the pentaquark of theta-plus has been hypothesized to exist. The pentaquark is a combination of two ups, two downs, and one antistrange quark. Determine the net charge on a pentaquark. Show all work and state why the antistrange has the charge it does.
Before hydrazine came in to use to remove dissolved oxygen in the water steam boilers, Na2SO3 was usually used for this purpose
A tanker truck carrying 2.01×10^3 kg of concentrated sulfuric acid solution tips over and spills its load. The sulfuric acid solution is 95.0% H_2SO_4 by mass and has a density of 1.84 g/L. Sodium carbonate Na_2CO_3) is used to neutralize the sulf..
What are the maximum allowable concentrations of these pollutants in the environment considered to be and how are these concentrations expressed?
A 10.00-mL sample of sulfuric acid from an automobile battery requires 35.08 mL of 2.12 M sodium hydroxide solution for complete neutralization.
Concentrated hydrochloric acid is 12 M and has a density of 1.18 g/mL. Calculate the mass in grams of a 0.025 L sample of concentrated hydrochloric acid.
Molecular beacons are nucleic acid strands that form hairpin loops. The stem region hybridizes to close the loop and the binding energy is ΔG = -22kJ/mole at 37°C.
Explain what is the net ionic equation for the reactions that take place when HCl and NaCl are added to the buffer CH3COOH + NaOH = NaCH3COO + H2O
Consider the assumption that the four molecules of interest have approximately the same molar mass and very similar polarizabilities such that the magnitude of the dispersion forces should be about the same.
