In a titration of HNO3, you add a few drops of phenolphthalein indicator to 50.00 mL of acid in a flask. You quickly add 20.75 mL of 0.0502 M NaOH but overshoot the end point, and the solution turns deep pink. Instead of starting over, you add 31.25 mL of the acid, and the solution turns colorless. Then, it takes 3.38 mL of the NaOH to reach the end point. (a) What is the concentration of the HNO3 solution? (b) How many moles of NaOH were in excess after the first addition?
Calculate the expected change in temperature for 4.5 g of NH4NO3 dissolved in 100.0 mL of H2O. Assume that the calorimeter absorbs no heat.
Balancing equation to calculate correct number of moles If CaC2 + 2 H2O --> C2H2 + Ca(OH)2 then, there are 65 grams of calcium carbide
whats the amount of heat required to raise the temperature of 165 g of water from 12.0 C to 88.0 C (sp. heat of H20(l)= 4.18 J/g)
65.50 mL of 0.161 M HF is titrated with 0.1200 M NaOH. What is the pH at the equivalence point? (Ka for HF is 6.8 x 10-4)
If 3.70 mol of ethane, C2H6, undergo combustion according to the unbalanced equation given below, how many moles of oxygen are required? C2H6 + O2-> CO2 + H2O
The second-order reaction, 2 Mn(CO)5 Mn2(CO)10 has a rate constant equal to 3.0 x 109 M-1s-1 at 25°C. If the initial concentration of Mn(CO)5 is 1.0 x 10-5 M.
A 62g piece of ice at 0 degree celsius is added to a sample of water at 9 degree celsius. All of the ice melts and the temperature of the water decreases to 0degree celsius. How many grams of water were in the sample ?
Creatine is a by-product of muscle metabolism, and creatinine levels in the body are known to be a fairly realiable indicator of kidney function.
