the electron pair geometry of a molecule is tetrahedral. what is its bond angle if it shows one lone pair of electrons and three
r-ruslan [8.4K]

<span>I think the correct answer is 109.5 degrees. The bond angle of a chlorite ion or ClO2- ion is 109.5 and has a bent shape. This is because of two groups of bonding electrons and two lone pairs of electrons. Another example of a molecule that has a bent molecular geometry is water. It results from its tetrahedral electron pair shape.</span>

There are 50 fish in the pond that have tags. You catch 25 fish, and 5 of them have tags. What is the best estimate of the numbe
sergeinik [125]

Answer: 250


Explanation:


You work this problem by using proportions.


A proportion is the equalization of two ratios.


Here you assume that the ratio of fish with tags to total fish that you catch is the same than the ratio of fish with tags to total fish in the pond.


Mathematically:

  • 5 fish with tag / 25 fish = 50 fish with tag / x
  • 5 / 25 = 50 / x

Solve for x:

  • Multiplication property of equality: x × 5 = 50 × 25
  • Division property of equality: x = 50 × 25 / 5
  • Result: 250
