A solution is prepared by dissolving 0.15mol of acetic acid and 0.15mol of ammonium chloride in enough water to make 1.0 L of solution. Find the concentration of ammonia in the solution.
Copper(I) chloride is a slightly soluble salt. The copper(I) ion also combines with Cl- in excess chloride to form the complex ion CuCl2-. Calculate the molar solubility of CuCl(s) in 0.0667 M KCl.
Balance the following redox equation using the smallest integers possible and select the correct coefficient for the hydrogen sulfite ion.
Write the overall reaction, showing how much ATP (Adenosine tri phosphate) can be produced per pentose used also write an equation for the generation of NADPH using ribose as a sole source of carbon?
Determine what percent by weight of sodium carbonate does it contain If the specific gravity of the sodium carbonate solution = 1.25,?
Nitrogen gas has a Henry's law constant k = 6.3 × 10-4 M/atm at 25°C. The "bends" in divers results from bubbles of N2(g) being rapidly released from body fluids when a diver ascends to the surface too quickly.
Calculate the temperature change in the water upon complete melting of the ice. Hint: Determine how much heat is absorbed by the melting ice and then use q =mC Delta T to calculate the temperature change of the 304 g of water.
