How will you prepare the following solutions from 6.0 M solutions of acetic acid and ammonia. Give exact details. Assume that a 10-mL graduated cylinder (in which volumes can be read to the nearest 0.1 mL) and a 100-mL graduated cylinder are available. a. 80 mL of 0.10 M HC2H3O2 b. 80 mL of 0.10 M NH3?
The % of antifreeze should be raised to twenty five percent by draining some of the mixture and adding 100% antifreeze determine how much mixture should be drained?
Water (2290g ) is heated until it just begins to boil. If the water absorbs 4.99×10^5J of heat in the process, what was the initial temperature of the water.
The temperature of the H 2 O is 26.55 degree celsius. Determine how much heat is evolved per gram of fuel burned?
Compute the enthalpy change for the dissolution of ammonium nitrate express your answers in units of kJ/mol.
what do you think Does it mean that their properties also differ from a classical model of matter?
A student has sample of HNO3 of 340 ml at 25 degrees celsius and add water of 110 ml at 95 degrees celsius then determine the final temperature of the mixture
Application of ideal gas law - How high can you raise the temperature of the gas without bursting the vessel?
Determine the volume of CO 2 at a temperature twenty two degree Celsius and a pressure of 781 mmHg could be absorbed by 327 grams of Lithium hydroxide LiOH?
total molarity of acid and conjugate base in this buffer. A boy mixes 5.70mL of a 0.330M Hydrochloric acid solution to the beaker. Determine the pH change if The pKa of acetic acid = 4.760.
