Answer:
Intermolecular forces (IMF) (or secondary forces) are the forces which mediate interaction between atoms, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules. Both sets of forces are essential parts of force fields frequently used in molecular mechanics.

Answer:
Probably D, Electron Cloud.
1 can of soda has 12 ounces * 2.01 mg/oz = 24.12 mg of caffeine.
1 gram = 1000 mg
10 grams x 1000 mg = 10,000 mg
Divide total mg by mg per can:
10,000 / 24.12 = 414.59 cans
Round to 415 cans
1. <em>Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. </em>
<em>2. Physical state of the reactants and surface area.</em>
Answer:
1
The heat of reaction is
The enthalpy is
2
The concentration of HCl is
Explanation:
From the question we are told that
The volume of is
The number of concentration of is
The volume of HCl is
The number of concentration of is
The temperature difference is
Now the heat of reaction is mathematically represented as
Where
is the specific heat of water with value
Now
where is the molar mass of NaOH with the value of 0.04 kg/mol
So
While
Where is the molar mass of with the value of 0.03646 kg/mol
So
=>
The enthalpy is mathematically represented as
=>
From the second question we are told that
The volume of HCl is
The volume of NaOH is
The concentration of NaOH is
The first temperature change is
The second volume of
The mass of NaOH is
substituting values
The mass of the product formed is
substituting values
The multiplication by 1000 is to convert it from kg to grams
Now the mass of HCl is
substituting values
Now the concentration of HCl is
The multiplication of is to convert it from kg/mol to g/mol
