Tresset [83]

Answer:

See explanation

Explanation:

The overall charge on ClO3−  is shown on the image attached to this answer. If we calculate the formal charges on each atom in the structure, we will notice that one oxygen atom has a formal charge of -1 while all other atoms have a formal charge of zero.

This gives the compound an overall charge of -1 as shown in the image attached to this answer. This is the correct Lewis structure for the compound ClO3− .

Block mountains form along which type of geological landform?
ozzi

Answer:

A. Fault blocks

Explanation:

The block mountains are formed by pieces of the crust that breaks down and pieces are pushed up by the movement of the crust around them.  These type of mountains usually have a steep and a slope side, due to the irregular nature of the fracture.  Example of such mountains are the Sierra Nevada mountains in North-America.

<u>They're not caused by the collision of two tectonic plates</u>, like most of the mountains of our planet.

The amount of I₃⁻(aq) in a solution can be determined by titration with a solution containing a known concentration of S₂O₂⁻³(aq
puteri [66]

Answer: 0.22 M

Explanation:

2S_2O_3^{2-}(aq)+I_3^-\rightarrow S_4O_6^{2-}(aq)+3I^-(aq)

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{moles}{\text {Volume in L}}

moles of Na_2S_2O_3=Molarity\times {\text {Volume in L}}=0.440\times 0.025=0.011moles

Na_2S_2O_3\rightarrow 2Na^+S_2O_3^{2-}

Thus moles of S_2O_3^{2-} = 0.011

According to stoichiometry:  

2 moles of S_2O_3^{2-}(aq) require 1 mole of I_3^

Thus 0.011 moles of S_2O_3^{2-}(aq) require=\frac{1}{2}\times 0.011=5.5\times 10^{-3} moles of I_3^-

Thus Molarity of I_3^-=\frac{5.5\times 10^{-3}}{0.025L}=0.22M

Therefore, the molarity of I_3^- in the solution is 0.22 M

Scientists found a fern fossil in some rock layers of the Grand Canyon. They estimated that a sample of one of the fossils origi
icang [17]
This question is dealing with the half-life of carbon-14 which can be used to determine the age of a substance according to the following equation:

t = [ln(N/No)/(-ln2)] · t1/2

N = # of carbon-14 atoms presently = 250 atoms
No = # of carbon-14 atoms initially = 1000 atoms
t1/2 = half-life = 5730 years for carbon-14

We can now input all of the information into the formula to find the age of the fossil:

t = [ln (250/1000)/-ln2] x 5730 years

t = 11460 years

The fossil should be found to be roughly 11,460 years old.
