5.15g of HCl(g), a strong acid, is dissolved in water to make a 210 mL solution. Calculate the pH of the resulting solution.
What volume of 5 M NaHCO3 solution
The enthalpy change for the reaction between W(s) and C(graphite) is difficult to measure directly because the reaction occurs at 1400degree C, W(s) + C(graphite) -- WC(s). However the heats of combustion of the elements and of tungsten carbide can ..
a sample of hydrated salt of 1.15 grams znso4.xh2o is dissolved in h2o and the sulfate ion is precipitated by adding an
Estimate the theoretical carbonaceous and nitrogenous oxygen demand of a waste containing 50 mg/L lysine, C6H14N2O2. Assume the nitrogen is liberated as ammonia in the first oxidation step converting organic carbon to CO2.
The theoretical yeild of Ni(NH3)6Cl2 moles must be calculated as well as the theoretical yield of Ni(NH3)6Cl2 grams. How do you find the limiting reagent to calculate the theoretical yield.
Write the structure for each functional group. Give an example of a molecule with a functional group and name appropriately.
For this lab, we had to separate 3 mixed compounds by means of simple distillation. After performing simple distillation, how do we determine the volume (or size) of the combined pure fractions for each of the three components
A 0.24ml sample of a weak acid with an unknown pKa was combined with 12.0ml of a 3.20M KOH and the resulting was diluted to 1.500L. The measured pH of the solution was 3.75. What is the pKa of the weak acid
Glycolysis produces NADH. However, NADH cannot cross the innermitochondrial membrane to be used in the electron transport chain(respiratory chain). The malate-aspartate shuttle in some animalcells transfers electrons from cytosolic NADH to the mat..
why the no. of electron changes by one or increases by one in
the equilibrium constant kp for the decomposition of nitrogen dioxide is 4.48 10-13 at 250c. what is the kc for that
If you titrate 1.0 g of H2O2 solution (30wt%) with KMnO4, 25.05 ml of this KMnO4 solution is used. What is the molarity of KMnO4?
