Could someone please provide me the steps as how to do this? I have the answer, and if you get it correct, I will rate you 5 stars.
How many grams of FeSO4.(NH4)2SO4.6H2O (MW = 392.14) must be dissolved and diluted to 250.0 mL to prepare an aqueous solution that is 10.00 ppm Fe2+ by weight (1.00 ppm = 1.00 mg/L)?
The concentration of a dye and concentration of bleach (NaOH) was determined experimentally by using Beer's Law. The rate constant is unknown. How do you calculate the reaction rate based on the graph of the reaction and the 2 concentrations of th..
You are a hazmat responder and walk into what appears to be a meth lab. There are flasks of iodine, White Gas fuel, Sodium Hydroxide, Nitric Acid, and a box of ephidrine.
A solution is prepared by adding 1.10 g of solid rm NaCl to 50.0 mL of 0.100 M {CaCl_2}. What is the molarity of chloride ion in the final solution? Assume that the volume of the final solution is 50.0 mL.
Write a net ionic equation for the precipitation reaction, if any, that occurs when aqueous solutions of the following ionic compounds are mixed. Cu(Ch3COO)2 and Na3PO4.
In the expression for f which you obtain, use a power series expansion of the exponential function
Determine how much heat (in kJ) is needed to warm 12.0g of ice, that is initially at -10.0 ° C, to steam at 114.0 ° C? The heat capacity of ice is 2.09 J/g⋅ ° C and that of steam is 2.01 J/g⋅ ° C.
At 25 degree celcius, the density of a 50 percent by mass ethanol/water solution is 0.914 g per subic centimetre. Given that the partial molar volume of water in the solution is 17.4 cubic centimeter per mol.
If 9 g of Kr initially at 0.2 bar and 15 L is brought to 0.49 bar and 5L, what is the overall change in enthalpy of this process? Assume that Kr is an ideal gas.
0.5g KCl was dissolved in 100g water and the solution originally at 200C, froze at - 0.240C. Calculate the percentage ionization of salt. Kf per 1000g of water = 1.86K
A mixture of CaCO3 and CaO weighing 0.630 g was heated to produce gaseous CO2. After heating, the remaining solid weighed 0.500 g.
