It forms an octahedral complex
Rh[NH3]5I
Explanation:
Or see structure attached below
<h2>Answer:</h2>
<u>Option B (S ^-2) is the correct answer</u>
<h2>Explanation:</h2>
Sulfur or sulfur is a chemical element with symbol S and atomic number 16. It means that it has 16 protons and 16 electrons. But when an atom of Sulfur gains two electrons, a minus 2 charge comes over it. Therefore it becomes an ion. So if it gained two electrons its electrons become 18 that is why S-2 is the correct answer.
There is a time delay of almost two to three minutes before the reaction proceeds because of the following processes:
<span>1) </span><span> The acid starts to go yellow as the dehydration begins.</span>
<span>2) </span><span> The rate of dehydration then accelerates as the acid heats up because the reaction is exothermic/chemical (releases energy by light or heat). As the sugar molecules are stripped of water, the heat generated turns the water into steam which then expands the remaining carbon into a porous, smoking, black column.</span>
<span>3) </span>This expands out of the reaction vessel, producing a choking acrid vapor and the smell of burned sugar.
<span> At this stage, sulfuric acid is highly corrosive and will burn skin so one must avoid contact with it. </span>
It acts as a skeleton for plants, protects the internal contents of the cell, and regulates cell growth
