Write balanced net ionic equation for the reactions that take place when the following reagents are mixed together in aqueous solution: Mg(s), H2SO4
Zn(s), CuSO4
The pressure is changed to 8.75 atm and the gas is cooled to 15 C. Calculate the new volume of the gas using the ideal gas equation.
Acid chlorides are used as electrophiles in the Friedel-Crafts reaction to prepare aromatic ketones. The reaction involves the transfer of an aromatic hydrocarbon with an acyl chloride in the presence of a lewis acid
a 40.0 ml volume of ethane gas is heated from 25.0 celcius to 50.0 celcius. If the pressure remains constant, what is the final volume?
What is the molarity of a solution if 4.50 g NaF is dissolved in enough water to make 250.0 mL of solution?
Draw formulas that illustrate the hydrogen bonding that may exist between two polyamide molecules after fibers have been cold drawn. In this lab,
M.r eric castilo purchased alot for PH 1300000 and sold them 2 years later for PH1900000. At what rate did his money earn?
solution requires 14.45 mL of 1.00 M NaOH for titration. How many molesof HCl are present in the solution? The density of 3 M HCl is 1.05 g/mL
In an acid base titration a 25mL portion of a solution containing sulfuric acid (H2SO4) was titrated with a 0.200M NaOH(aq). write the chemical equation for this particular titration

Predicting nuclear stability is important when determining whether or not a nuclear reaction can take place spontaneously.
How many moles of water can be produced by 12.5 moles of C4H10 with excess oxygen?
What combination of a molecular base (that is a neutral compound, not an ion!) and a salt of the conjugate acid of that molecular base should you select to prepare a buffer solution that would maintain a pH of 9.00? For full credit, explain
