If the aqueous solution in the above problem with ammonia was also allowed to equilibrate with an atmosphere containing 103.5 atm carbon dioxide, estimate the new equilibrium pH for the solution. Try the log concentration-pH approach. Will it be possible to solve this problem algebraically? How?
The concentration of Mg2+ in seawater is 0.052 M. At what pH will 72% of the Mg2 be precipitated as the hydroxide salt? [Ksp for Mg(OH)2 = 8.9 multiplied by 10-12.]
Consider the following equation: 2Mg(s) + O2 (g) → 2MgO(s). How many grams of MgO are produced when 40.0 grams of O2 react completely with Mg?
Use the density of copper (8.95 g/cm3) and its molar mass (63.55 g/mol) to calculate an approximate atomic radius for copper.
Metals and nonmetals can react with each other to form ions. Complete these statements. A potassium atom gain or loses(electrons/protons/neutrons)and to form how many ion?
Identify what complementary functional group would need to be present in the neuraminidase active site for (a) hydrogen bonding and (b) ioic interactions to oseltamivir to be observed?
Determine At what temperature will Kp 2.00? if it is given that Delta H = +57.2 kJ/mol,Kp = 0.113 at the temperature of 298 Kelvin?
An electron in an excited state of a hydrogen atom emits two photons in succession, the first at 1817 nm and the second at 97.20 nm, to return to the ground state (n=1).
Consider the cell described below. Al | Al3+ (1.00 M) || Pb2+ (1.00 M) | Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.32 mol/L. (Assume T = 25°C.)
Organic chemistry- When 2-butene reacts with hydrogen chloride gas, only one product is detected, whereas when 1-butene reacts similarly
liquid NCl3 in a 2.50L closed container is heated until it decomposes completely to gaseous products. the resulting mixture exerts a pressure of 745mm Hg at 95 degrees celsius
Calculate the theoretical yield of C2H5Cl when 110 g of C2H6 reacts with 226 g of Cl2, assuming that C2H6 and Cl2 react only to form C2H5Cl and HCl.
