4. Some biologists declare "structure determines functions." The 3-D molecular geometry in small molecules (or units of molecule

s) are critical in the final shape of larger structures. Give an example, not found in your notes or textbook that illustrate how a change a final shape can affect how the structure functions (or how other substances interact with it) and explain your choice.​

The following molecular equation represents the reaction that occurs when aqueous solutions of silver(I) nitrate and calcium chl
dsp73

Answer:

Ag+(aq) + Cl-(aq) —> AgCl(s)

Explanation:

2AgNO3(aq) + CaCl2(aq) —>2AgCl(s) + Ca(NO3)2(aq)

The balanced net ionic equation for the reaction above can be obtained as follow:

AgNO3(aq) and CaCl2(aq) will dissociate in solution as follow:

AgNO3(aq) —> Ag+(aq) + NO3-(aq)

CaCl2(aq) —> Ca2+(aq) + 2Cl-(aq)

AgNO3(aq) + CaCl2(aq) –>

2Ag+(aq) + 2NO3-(aq) + Ca2+(aq) + 2Cl-(aq) —> 2AgCl(s) + Ca2+(aq) + 2NO3-(aq)

Cancel out the spectator ions i.e Ca2+(aq) and 2NO3- to obtain the net ionic equation.

2Ag+(aq) + 2Cl-(aq) —> 2AgCl(s)

Divide through by 2

Ag+(aq) + Cl-(aq) —> AgCl(s)

The, the net ionic equation is

Ag+(aq) + Cl-(aq) —> AgCl(s)

A student determines the molar mass of a compound by the method used in this experiment. She found the temperature of the ice wa
cluponka [151]

Answer:

139.94 grams of solute is present in  kilograms of water

Explanation:

Temperature of the ice water = T = 1.0°C

Temperature of the mixture = T_f =-3.0°C

Depression in freezing point \Delta T_f=T-T_f

\Delta T_f =1.0°C-( -3.0°C)=4°C

\Delta T_f=k_f\times m=k_f\times \frac{\text{Moles of solute}}{\text{mass of solvent (kg)}}

m = molality of the solution

k_f = Molal depression constant

4^oC=1.86^oC kg/mol\times \frac{\text{Moles of solute}}{0.0793 kg}

Mole of solute = 0.1705 moles

Mass of solute = 11.1 g

Moles of solute = 0.1705 mol=\frac{11.1 g}{M}

Molar mass of the solute= M

M = 65.088 g/mol

Molality of the solution = m = \frac{0.1705 mol}{0.0793 kg}

m\times M=\frac{0.1705 mol}{0.0793 kg}\times 65.088 g/mol=139.94g of solute /kg of water

139.94 grams of solute is present in  kilograms of water
