Can someone provide an in-depth explanation (around 200-300 words) on how increasing surface area of a solid reactant affects the rate of reaction?
grams is added to a flask with a volume of 24.5 mL. It is found that 18.52 grams of water (d=0.9970 g/ml) must be added to fill the flask. What is the density of the metal?
what is the mass of 2.50 liters of an intravenous glucose that has a density of 1.05g/ml. A patient is required to take 0.400 mg of ampicillin / day. Ampicillin is available as a liquid suspension at a concentration of 50.0mg/5.0 m. How many ml of..
The Ka of HNO2 is 7.1 x 10^-4. Use this to find the volume (mL) and pH of 0.0588 M KOH needed to reach the equivalence point(s) in titrations of 28.5 mL of 0.0380 M HNO2.
In a closed 1.00 L flask, 2.60 atm of CO reacts with 5.80 atm of O2 according to the equation below. Assuming that the temperature remains constant, what is the final pressure in the flask?
