What is the role of blister copper during industrial production of copper
Fifty mL of a monoprotic weak acid was titrated with 0.0470 M NaOH. About 14.26 mL of NaOH was required to reach the equivalence point. At the equivalence point, the pH was 10.0. What was the pH when only 9.70 mL of NaOH had been added
given two separate solutions 0.100 m ammonia and 0.100 m ammonium chloride calculate the volume of each solution to
when 25.0ml of .500m h2so4 is added to 25.0ml of 1.00m koh in a coffee cup calorimeter at 23.50 degree celcius the
When hcl and nahco3 are mixed together, a chemical reaction takes place in which a gas is one of the products. What is the molar mass of a sample of gas
The solution to 2.00 L and then shows an absorbance of 1.096. 50.0 mL of the solution is then mixed with 15.0 mL of 4.00 x 10^-4 M KMnO4 and the absorbance of the resuling solution is 1.097. what was % w/w Mn in the steel? (% w/w). FM of Mn is 54...
Balance the following molecular equations for these reactions. Write the ionic equation for the reactions. Write the net ionic equation for the reactions.
If you were given a clear colorless solution as well as asked to determine whether or not protein was present, would a UV scan of the solution be adequate to answer the question. Explain.
Problem- Draw the Lewis structure (including resonance structures) for methyl azide (CH3N3). For each resonance structure, assign formal charges to all atoms that have formal charge.
In ESI, it is very important to regulate the pH of the solution. Therefore, the solution is usually buffered or has added acid. How does the solution pH influence the ionization efficiency and the distribution of charged species formed?
A student mixes 88.6g of water at 74.3 degree Celsius with 57.9g of water at 24.8 degree Celsius in an insulated flask. What is the final temperature of the combined water.
