Answer:

35.45 amu is the average atomic mass of chlorine.

Explanation:

The average atomic mass is given :

\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i

Atomic mass of 35-Cl = 34.968 amu

Percentage abundance of 35-Cl = 75.53%

Fractional abundance of 35-Cl = 0.7553

Atomic mass of 37-Cl = 36.956 amu

Percentage abundance of 37-Cl = 24.47%

Fractional abundance of 37-Cl = 0.2447

Average atomic mass of chlorine:

=34.968 amu\times 0.7553+36.956 amu\times 0.2447=35.45 amu

35.45 amu is the average atomic mass of chlorine.

A decrease in the magnitude of velocity is called
IceJOKER [234]
<span>The answer is deceleration. Acceleration is the general term to refer to the change in velocity. Acceleration = change in velocity / change in time. When you want to highlight the fact that the change in velocity is a decrease in the magnitude, you can use the term deceleration, which means that the acceleration is negative.</span>

Write a net ionic equation to show that hydrobromic acid, hbr, behaves as an acid in water.
Harrizon [31]
The net ionic equation of hydrobromic acid would be HBr = H+ + Br-. As we can see, the HBr compound dissociates into ions where one ion is the hydronium ion which characterizes an acid. According to Arrhenius, an acid is a compound which releases hydronium ion in solution.
