Surfactants disrupt intermolecular forces inside liquids and viscosity is directly related to intermolecular forces so, if intermolecular forces are decreased, viscosity should decrease as well.
Answer:
c. −1.22 × 10^4 K
Explanation:
Generally, the slope of an Arrhenius plot can be determined either from the graph of In k against 1/T or the available experimental data of the rate constant (k) and the absolute temperature. Mathematically,
Where:
L/(mol.s)
L/(mol.s)
K
K
slope = (ln 2.9*10^-1 - ln 6.6*10^-4)/(1/500 - 1/400)
slope = (-1.238+7.323)/(0.002-0.0025)
slope = 6.085/-0.0005 = -1.22*10^4 K
Determine the mass of each of the following amounts. a. 1.366 mol of
NH3
, b. 0.120 mol of glucose,
C6H12O6
, c. 6.94 mol barium chloride,
BaCl2
, d. 0.005 mol of propane,
C3H8
Mol (n) = 29.0
molar mass (M) Na = 23 g/mol
mass (m) = ?
m = nxM
m = 29.0x23
m = 667 g
mol (n) = 29.0
molar mass (M) Cl = 35.5 g/mol
mass (m) = ?
m = nxM
m = 29.0x35.5
m = 1029.5 g
