3. List the temperatures in order from warmest to
amid [387]

Answer:

3°F, 0°F, -11°F,  -16°F, -20°F

Explanation:

The Fahrenheit scale is a temperature scale proposed in 1724  by the physicist Daniel Fahrenheit.

In this scale:

- The freezing point of water is set at 32 degrees

- The boiling point of water is set at 212 degrees

One degree in the Fahrenheit scale is indicated with the symbol ^{\circ}F.

The equivalence between temperature in Celsius degrees and Fahrenheit degrees is as follows:

T(^{\circ}C)=\frac{5}{9}(T(^{\circ}F)-32) to convert from Fahrenheit to Celsius

T(^{\circ}F)=\frac{9}{5}(T(^{\circ}C)+32) to convert from Celsius to Fahrenheit

The Fahrenheit  scale is an increasing monotonic scale, it means that temperature goes from negative values towards positive values without interruption. Therefore, the temperatures listed from warmest to coldest are:

3°F, 0°F, -11°F,  -16°F, -20°F

What do I scan to confirm that a book is relevant and valuable as a source
Elden [556K]
It's genre. Look for something either on a final or starting page near the cover, and check to look if it's non fiction, or anything else that could prove it as reliable.

(a) a 0.2 m potassium hydroxide solution is titrated with a 0.1 m nitric acid solution. (i) balanced equation: (ii)what would be
Stells [14]

\text{KOH} (aq) + \text{HNO}_3 (aq) \to \text{KNO}_3 (aq) + \text{H}_2\text{O} (l)

The solution shall contain only \text{KNO}_3 (aq) (and water) at the equivalence point. Both potassium hydroxide and nitric acid exist as strong electrolytes. As a result,  \text{KNO}_3 (aq), the salt derived from a reaction between the two species would undergo hydrolysis of a negligible extent. This neutralization reaction therefore be neutral at the equilibrium point.

The question states that the solution is "titrated with a ... nitric acid solution" indicating that \text{HNO}_3 is added to the initially-basic solution. PH value of the solution would keep decreasing as the volume of the acid added increases. The final solution would be acidic as it contains not only water and \text{KNO}_3 (aq), but some \text{HNO}_3 as well. Bromothymol blue would therefore demonstrates a yellow color, the color it present in an acidic solution, at the end of the titration.

gulaghasi [49]

The major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.

<h3>What are carbohydrates?</h3>

Carbohydrates are biological macromolecules that function as macronutrients by providing energy, which are composed of simple carbon-based molecules linked by glycosidic bonds.

In conclusion, the major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.
