Identify the four parts of the potential energy diagram

Chemistry
1 answer:
Leni [432]2 years ago
4 0

Answer:

Reactants, Activation energy, Energy released by the reaction and Products

Explanation:

This energy profile is that of an exothermic reaction. In an exothermic reaction, heat is liberated to the surrounding. The surrounding becomes hotter than the environment.

The first box to the left is the reactants which signifies the species combining together.

The topmost box is the activation energy which is the energy barrier that must be over come before a reaction takes place.

The box underneath is the energy change. Here, energy is being released.

The right most box is the product of the reaction.

A mothball, composed of naphthalene (c10h8), has a mass of 1.64 g . part a how many naphthalene molecules does it contain?
OLga [1]
The molar mass of Naphthalene is 128g/mol
Therefore; a mass of 1.64 g of Naphthalene contains'
   = 1.64g/128 g
    = 0.0128 moles
But, from the Avogadro's law 1 mole of a substance contains 6.022 × 10^23 particles
Therefore 1 mole of Naphthalene contains 6.022×10^23 molecules
Hence; 0.0128 moles × 6.022 ×10^23 molecules
          = 7.716 × 10^21 molecules

A molecular orbital is a region of space in a covalent species where electrons are likely to be found. The combination of two at
lara [203]

Answer:

bonding molecular orbital is lower in energy

antibonding molecular orbital is higher in energy

Explanation:

Electrons in bonding molecular orbitals help to hold the positively charged nuclei together, and they are always lower in energy than the original atomic orbitals.

Electrons in antibonding molecular orbitals are primarily located outside the internuclear region, leading to increased repulsions between the positively charged nuclei. They are always higher in energy than the parent atomic orbitals.
