On the left (reactant) side you have 6 N-H bonds and 1 Cl-Cl bond
<span>On the right (product) side you have 4 N-H bonds, 1 N-N bond and 2 H-Cl bonds </span>
<span>Add up the bond energies for each side (multiplying by the number of bonds) and calculate the difference for your ΔHº</span>
Answer:
true
Explanation:
osmosis is a special case of diffusion. diffusion occurs across a semipermeable membrane and only the water or other solvent moves. Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution.
Answer:
0.264 mol/L
Explanation:
Data obtained from the question includes:
Volume = 5.74L
Mass of FeCl3 = 246 g
Molarity =?
Next, we shall determine the number of mole in 246g of FeCl3.
This is illustrated below:
Mass of FeCl3 = 246g
Molar mass of FeCl3 = 56 + (35.5x3) = 162.5g/mol
Number of mole of FeCl3 =..?
Mole = Mass /Molar Mass
Number of mole of FeCl3 = 246/162.5
Number of mole of FeCl3 = 1.514 mol
Now, we can obtain the molarity of the solution as follow:
Molarity = mole /Volume
Volume = 5.74L
Mole of FeCl3 = 1.514 mol
Molarity = 1.514/5.74
Molarity = 0.264 mol/L
Answer:
condensation - B, melting - C, sublimation - A, freezing - D
Explanation:
condensation : condenstaion is process of change of phase of a substance from gaseous to liquid
evaporation : evaporation is process of change of phase of a substance from liquid to gaseous.
melting : melting is process of change of phase of a substance from solid to liquid.
freezing : freezing is process of change of phase of a substance from liquid to solid.
sublimation : sublimation is process of change of phase of a substance from solid to gaseous.
