While a solution containing 1.4g of Ba(NO3)2 as well as 2.4g of NH2SO3H is boiled, a precipitate forms. This precipitate may be Ba(NH2SO3)2, BaSO4, or Ba(NH2)2. Determine these products in the reactions whose equations you balanced in the first question.
a. Evaluate the number of moles of each reactant.
b. Find out the limiting reactant in each of the subsequent three reactions.
Sketch bonding orbitals that result from combinations of the following orbitals on separate atoms (a) pz and dz2 (b) s and pz (c) dx2-y2 and dx2-y2
What happens to carboxylic acid when it reacts with 1M NaOH and show the reaction. How does this change its solubility. Which compounds are now in each solution
The Ksp of AgCl at 25 oC is 1.6 x 10-10. Consider a solution that is 1.0 x 10-4 M NaCl and 1.0 x 10-6 M AgNO3. 1. The solution is saturated.
The initial temperature was 27.0 degrees Celsius and the final temperature after the addition of metal was 32.5 degrees Celsius. What is the Cp for the metal
Justify whether the following closed system processes have ?U, q, w and ?H increase, decrease or remain the same (0). a) a gas (closed system) is expanded isothermally (gas pressure remains under 5atm of pressure)
What is the molarity of a HCl solution if the reaction of 200 mL of the HCl solution with excess CaCO3 produces 14.0 L of CO2 gas at 725 mmHg at 18 degree celsius.
how does the average kinetic energy of different gases compare when they are at the same temperature?
HF is a stronger acid than HBR because F has greater electronegativity than Br 2) the acid (HA) strength will increase when the H-A bond strength increases
Consider the following reaction. N2 + 3 H2 → 2 NH3 . 28.0 grams of N2 and 5.04 grams of H2 are reacted, producing 17.8 grams of NH3. What is the percent yield?
A gas expands and does P-V work on the surroundings equal to 323 J. At the same time, it absorbs 145 J of heat from the surroundings.
Calculate the number of grams of NaOH per 100ml to give a pH8.0 solution if pure water at pH7.0 is used in the experiment. Repeat this calculation for a pH6.0 solution using HCl.
