Problem- Enough of a monoprotic acid is dissolved in water to produce a .0159 M solution. The pH of the resulting solution is 6.43. Calculate the Ka for the acid.
Explain each and every step in detail. I need proficient help in the above problems.
Distinguish between a bonding orbital and an anti bonding orbital in terms of their contributions
12.00 g of an unknown nonelectrolyte in enough water to make 2.00 L of solution. The osmotic pressure of this solution is 0.750 atm at 25.0°C. What is the molecular weight of the unknown solute (R = 0.08206 L•atm/K•mol)
At room temperature (20 degrees Celsius), milk turns sour in about 64 hours. In a refrigerator (3 C) milk can be stored 3 times as long before it sours. Explain how long should it take milk to sour at 40 C
The rate constant of a reaction is 4.7 10-3 s-1 at 17°C and the activation energy is 33.6 kJ/mol. What is the value of k at 75°C.
Can some explain clearly how to determine the valence electrons of transitional metals and also their ions. for ex Mo, Mo2+, Ag, Pb. Pb2+. Confuse about what makes up their outer shell.
Draw the two possible products of the reaction between benzaldehyde and ethylpropylketone
indicate how the partial pressure of hydrogen will change if the following stresses are applied to the equilibrium
Explain how much energy in kilojoules is needed to heat 5.00g of ice from -10.0 degrees Celsius to 30.0 degrees Celsius? The heat of the fusion of water is 6.01 kJ/mol, as well as the molar heat capacity is 36.6 j/(k . mol) for ice as well as 75.3..
A general statement concerning the solubility of organic compounds is: The smaller molecules dissolve best in a solvent with a low molecular weight.
The reaction is thought to follow second order kinetics which follows the relationship 1/[A]=1/[A]0+kt where [A] is the molarity at time, t, and [A]0 is the initial concentration.
