A patient weighs 146 pounds and is to receive a drug at a dosage of 45.0 mg per kg of body weight. The drug is supplied as a solution that contains 25.0 mg of drug per mL of solution. How many mL of the drug should the patient receive? [Use: 1 pound = 454 g]
The H2O molecules above and below the equatorial plane are more loosely bound. For convenience this ion is often written as Cu^2+(aq) Addition of NaOH to the Cu^2+ (aq) solution causes a precipitate of Cu(OH)2. write a balanced equation regarding ..
Oxalic acid, H2C2O4 has acid dissociation constants Ka1 = 5.9 x 102 and Ka2 = 6.4 x 105. What is the pH after 20.00 mL of 0.0500 M NaOH is added to 5.00 mL of 0.2000 M H2SO3
The relationship between Kp and Kc for gaseous reactions depends on the change in the total moles of gas between reactants and products. For each of the equations given at the right, select the correct relationship between Kp and Kc from the list ..

If a solution containing 46.46 g of mercury(II) acetate is allowed to react completely with a solution containing 7.410 g of sodium sulfide, how many grams of solid precipitate will be formed?
The equilibrium expression for the reaction: 2C(s) + 2H2O(I) ? CH4(g) + CO2(g) is Keq = [CH4][CO2]. If an equilibrium reaction shifts to the right when the system is cooled, this indicates that the reaction is endothermic
Which pair is written with the first member having the higher boiling point?
