Depict a Lewis structure for each of the subsequent molecules or ions. Explain the electron-pair geometry as well as the molecular geometry around the central atom XeF4 and NH2Cl.
The melting of ice requires 1.44 Kcal/mol. If this energy goes into breaking H-bonds, how many H-bonds will there be in liquid water at 0°C?
Rubidium chloride has the rock salt structure. Cations and anions are in contact along the edge of the unit cell, which is 658 pm long. The radius of the chloride ion is 181 pm. What is the radius of the Rb+ ion?
the shark tank at an aquarium houses 5 sharks that deplete theaquarium water of a total of 50.00 grams of oxygen per
A calorimeter with a heat capacity of 4.61 kJ/K contains 18,050 g of freon-12. Benzoic acid is combusted in the calorimeter and liberates 26,400 J of heat energy causing the temperature to rise 3°C. Calculate the specific heat of freon-12 in J/g°C..
