A sample of neon gas at 745 torr and 60.0 L is compressed to 14.5L. If the temperature remains constant, what is the final pressure of the gas?

Which substance has the weakest intermolecular forces?

The mole ratios among the reactants and products in a chemical reaction.

How many grams of sodium chloride (NaCl, 58.44 g/mol) are needed to make up 250. mL of a solution that is 2.00 M?

In the chemical equation below, in the direction in which it is written, which is the oxidizing agent? Sn2+ + Br2 –> Sn4+ + 2Br-

For an ideal gas, considering the number of moles being constant, which one of the following graphs describing the relationship between pressure (P), volume (V), and temperature (T), is INCORRECT ?

What is the net ionic equation for the balanced reaction of aqueous ammonium chloride with aqueous lead (II) nitrate?                                    NH4Cl(aq) + Pb(NO3)2(aq) –>  ?

Use the dropdown boxes to balance the reactions below.  If a coefficient is one, normally we would leave it blank.  However, for the sake of testing it will be okay to choose “1” for balancing an equation.  Fe2O3 + H2SO4 –> Fe2(SO4)3 + H2O

NaOH forms a strong electrolyte in an aqueous solution.

Using formal charges, predict the most favored structure.
