Answer:
Potassium iodide increases the decomposition rate of hydrogen peroxide.
Explanation:
Potassium iodide increases the decomposition rate of hydrogen peroxide because potassium iodide act as a catalyst. A catalyst speed up the process of chemical reaction without reacting with the molecules present in reaction. If the potassium iodide is not present as a catalyst for the decomposition of hydrogen peroxide then the decomposition of hydrogen peroxide takes too much time because the catalyst is absent that speed up the reaction.

Answer:
A. The molecular orbital theory of bonding is based on the mixing of atomic orbitals of similar shapes and energies to form molecular orbitals that extend to two or more atoms
Explanation:
When two atoms come close to each other, the waves of their atomic orbitals can interfere constructively or destructively, to form two new molecular orbitals that encompass the whole molecule.
B is wrong. It refers to Lewis structures.
C is wrong. It refers to VSEPR theory.
D is wrong. It refers to ionic bonding.
E. is wrong. It refers to valence bond theory.

Answer: 893.7K
Explanation:
From the question, we obtained the following:
V = 54L
n = 2.8moles
P = 3.8 atm
R = 0.082atm.L/mol /K
T =?
Applying the ideal gas equation, we have:
PV = nRT
T = PV /nR
T = (3.8x54)/(2.8x0.082)
T = 893.7K
