If you lived in Alaska, which of the following natural gases could you keep in an outdoor storage tank in winter: a. Methane (CH
wariber [46]

Answer:

Methane

Explanation:

The gas that you could keep in an outdoor storage tank in winter in Alaska is Methane.

The reason is the extreme low temperature during the winter. The boiling point of butane is 44 ºF ( -1ºC) and that of propane is a higher -43.6 º F but still within the range of average minimum winter temperature in Alaska (-50 ªF). Therefore we will have condensation in the tanks and not enough gas pressure.

Methane having  a boling point  of  -259 ºF will not condense at the low wintertime temperatures in Alaska.

Suppose you want to use a combustion chemical reaction to cook hot dogs and hamburgers. what type of reaction would you want? a
guajiro [1.7K]

Answer : The correct answer is a) an exothermic reaction that releases energy.

Combustion reaction is generally referred as burning or when hydrocarbon reaction with oxygen to produce carbon dioxide and water . Combustion reaction releases energy. Example :

CH₄ + O₂ → CO₂ + H₂O + Energy or heat .

The reaction which releases energy or heat are known as Exothermic reactions .

Since it says hot dogs and hamburgers are cooked means they are undergoing combustion chemical reaction and so they are exothermic reactions. So option a) an exothermic reaction which releases energy is correct .

Explain how Beer’s law can be applied in food, drug or medical testing
KonstantinChe [14]
<h2>Answer with explanation:</h2>

<em><u>Beer's Law is described as if a light passes from a solution, the concentration of the solution is directly proportional to the  absorbance of light by that solution.</u></em>

Every element has a definite of absorbance of light.

In the testing of food, drugs or in medical testing, the light is passed from the sample.

Them transmitted light from these samples are measured. The difference between target light amount and transmitted light is the amount of absorbed light.

From this absorbed light value, we can identify an element in sample and its quantity.

Spectrophometry is based on this law.
