Answer:
Nucleophilicity refers to the ability of a nucleophile to displace a leaving group in a substitution reaction. We will describe trends in nucleophilicity in Chapter 10. Most common nucleophiles have a negative charge. However, it is the nonbonding electron pair that is important.
By increasing the the heat, it increases the kinetic energy of molecules.
0.05 liters of 0.40 M calcium chloride solution
Explanation:
We have the following chemical reaction:
Na₂CO₃ + CaCl₂= 2 NaCl + CaCO₃
Chalk is calcium carbonate CaCO₃.
number of moles = mass / molecular weight
number of moles of CaCO₃ = 2 / 100 = 0.02 moles
From the chemical reaction we see that 1 mole of calcium chloride (CaCl₂) produces 1 mole of calcium carbonate (CaCO₃), so to produce 0.02 moles of calcium carbonate (CaCO₃) we need 0.02 moles of calcium chloride (CaCl₂).
molar concentration = number of moles / volume (L)
volume = number of moles / molar concentration
volume of calcium chloride solution = 0.02 / 0.4 = 0.05 liters

What mass of water is needed to dissolve 34.8 g of copper(II) sulfate in order to prepare a 0.521 m solution? Calculate the freezing point of a solution made from 32.7 g of propane, C3H8, dissolved in 137.0 g of benzene, C6H6. The freezing point of benzene is 5.50° C and its Kf is 5.12° C/m.\ Calculate the concentration of nitrogen gas in a 1.00 L container exerting a partial pressure of 572 mm Hg at room temperature. Henry’s law constant for nitrogen at 25° C is 6.8 x 10-4 mol/L·atm.
