Answer:
The value is 
Explanation:
From the question we are told that
The bond length is 
The bond dipole moment is 
Generally the dipole moment is mathematically represented as
Here Q is the partial negative charge on the bromine atom
So
=> 
=> 
Generally
1 electronic charge(e) is equivalent to 
So x electronic charge(e) is equivalent to
=> 
=>
Answer:
Conduction is heat transfer through the direct contact of two subjects. The best example of this would be C, because it is the direct transfer of heat from the lightbulb to your hand. :)

Answer:
Q1: 2. Molarity.
Q2: 2.51 x 10⁻³.
Explanation:
<u><em>Q1:</em></u>
- The molarity is defined as the no. of moles of solute in one liter of solution.
- It is can be calculated from the relation: M = (no. of moles of solute)/(Volume in L of the solution).
<u><em>Q2:</em></u>
∵ pH = - log[H₃O⁺]
∴ 2.60 = - log[H₃O⁺]
log[H₃O⁺] = -2.6.
<em>∴ [H₃O⁺] = 2.51 x 10⁻³.</em>
