a) For your cereal sample, you added the same volume of sodium acetate that you added to your standards and solution unknown. b) You forgot to add hydroxylamine hydrochloride when you prepared the standards, but you added it when you did the cereal analysis. For part b, include a sketch of a Beer's Law plot to explainhow the error would affect the calibration line and the wt% Fe determined for the cereal. (Onthe sketch, use a solid line to represent the correct calibration line and a dotted line for the line with the systematic error.) Also discuss the advantages and disadvantages of spectral methods of analysis

Under certain conditions, the formation of ammonia from nitrogen and hydrogen has an 8.12% yield. Under such conditions, how many grams of NH3 will be actually produced.
I need help writing the balanced formula equation and the net ionic equation for the reaction of sodium hydroxide with hydrocholoric acid.
What is the concentration of A^3- ions at equilibrium for a 0.10 M solution of a hypothetical triprotic acid H3A, with Ka1 = 6.0 x 10^-3, Ka2 = 2.0 x 10^-8, Ka3 = 1.0 x 10^-14 ?
How do you calculate the force of water hitting a concrete cylindrical pole. The velocity of the water is 2 ft/s, the depth of the water is 10 ft, and diameter of the pole is 3 ft. So what would be the total force exerted on the pole by the water?
A sample of neon gas has a volume of 282 mL AT 160 degrees celsius. The sample is cooled at constant pressure to a volume of 685 mL. What is its new temperature?
Determine how much energy will be required to heat 69.7 gal of H 2 O from 22 degree Celsius to 110 degree Celsius if it is given that 1.00 gal weighs 3.77 kg and water has a specific heat capacity =4.184 J/g C
Consider the following reaction for the dissociation of benzoic acid (MW=122 g x mol^-1) in water where Ka for benzoic acid is 6.5 x 10^-5. C6H5COOH(aq) + H2O (l) C6H5COO-(aq) + H30+(aq)
The exothermic chemical reaction CO(g) + H2O(g) CO2(g) + H2(g) has Kc = 0.034 at 25°C. We currently have a flask containing all the components listed in this equation at equilibrium at 25°C. Subsequently, we will either (1) add some H2 to the flas..
