A 1.45 g sample of an iron ore is dissolved in an acid and the iron is obtained as Fe+2 (ag). To titrate the solution, 21.6 mL of 0.102 M KMnO4 (aq) is required. The Fe+2 solution reacts with MnO4- as follows: 5Fe+2 (aq) + MnO-4 (aq) + 8H+ (aq) --------> 5Fe+3 (aq) + Mn+2 (aq) 4H2O (l) What is the percent of iron in the ore?.
A mixture of nitrogen and hydrogen was allowed to come to equilibrium at a given temperature according to 3H2+N2 2NH3. At equilibrium, the mixture contained
Use the observations and arrange the following five reduction half-cell reactions in order, the one with the largest positive reduction potential listed first.
A chemist wants to make 4.5L of a 0.340M CaCl2 solution.What mass of CaCl2 (in g ) should the chemist use?
solution if its conjugate acid. What is the pH of this combined solution? Always give two numbers after the decimal place
This procedure is potentially very lucrative because, after an initial extraction of energy from the groin, no fossil fuels would be required to keep the device running indefinitely. Would you invest in this idea? State your conclusion clearly and..
How would you calculate the pH of a mixture made from adding 20.0 g of NaCH3CH2COO and 20.0 g of CH3CH2COOH to 100.0 mL of 0.10 M HCl.
Which of the following buffers will have the lowest pH?
An experiment requires 45.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
Assume that you have a cylinder with a movable piston. What would happen to the gas pressure inside the cylinder if you do the following? Decrease the volume to one third the original volume while holding the temperature constant.
Determine the amount of energy or work that the silicon nitride tip could absorb before being plastically deformed, assuming no initial cracks. Volume is in part A.
Lewis Structure for a Nitrate Ion (NO3-1). For the correct structure of the nitrate ion, what is the bond angle from O-N-O
How many grams of Ca(OH)2 are needed to neutralize 3.6 moles of HCl in 655 mL of solution? The molar mass of HCl is 36.46 g/mol. The molar mass of Ca(OH)2 is 74.1 g/mol.
