Answer:

2KOH(aq) + NiSO₂(aq) → K₂SO₄(aq) + NiOH₂(s)

Explanation:

This reaction is an example of a <em>double-replacement reaction </em>where the cations of two compounds exchange with its anions. In the reaction:

KOH(aq) + NiSO₄(aq)

There are produced K₂SO₄ and NiOH₂ salts (The last one is insoluble, its state is (s) but K₂SO₄ is very soluble, its state is (aq). The unbalanced reaction is:

KOH(aq) + NiSO₄(aq) → K₂SO₄(aq) + NiOH₂(s)

To balance the potassiums:

<h3>2KOH(aq) + NiSO₂(aq) → K₂SO₄(aq) + NiOH₂(s)</h3>

And now, the reaction is balanced

A student performs three trials of a titration of an acid with an unknown concentration. She compares her measured concentration
Viktor [21]

Answer:

There are many errors possible while titrating the acid of an unknown concentration with a base like NaOH.

Main error that leads to the error in results is misreading of the end point volume .

End point is when the reaction between the analyte and solution of known concentration has stopped .

Sometimes Burette is not straight enough to read the volume of the end point. One way to misread the volume of burette is by looking at the burette volume at an angle .

From above , volume seems to be higher. Indicators are used to indicate the color change of the reaction. In Acid-Base titrations , indicators first lighten up then changes its color.

So, error may have occurred in wrongly judging of the end point by color change of the indicator .

compare the boiling point of water at sea leavel to the boiling point in denver (altitude = 1 mile) Explain
steposvetlana [31]

Answer:

boiling point decreases in denver

Explanation:

in higher places

theres less atmospheric pressure

it takes less energy to bring water to the boiling point.

Less energy means less heat

which means water will boil at a lower temperature
