Calculate the food energy (joules/
Anna007 [38]

Calculate the food energy (joules/g) of one of your food samples. one chemistry calorie is equal to 4.186 joules. convert the energy you calculated to kilojoules (1 kj = 1000 j). since nothing is given, an example is avocadoes have 160 cal/100 g serving

(160 cal/ 100 g)(4.186 J/ 1 cal) (1 kJ/1000 J) = 0.0067 kJ/g

Why would you need a locating agent in an experiment to separate amino acids by chromatography
Nadusha1986 [10]

A locating agent is needed in an experiment to separate amino acids by chromatography as it helps to analyze colorless substances on paper.

<h3>What is chromatography?</h3>

Chromatography is an analytical method frequently used to separate a chemical mixture into its components, allowing for in-depth analysis of each component.

There are many different types of chromatography including liquid, gas, ion-exchange, and affinity chromatography, but they all use the same basic principle.

<h3>What is the use of a locating agent in Chromatography?</h3>

In paper chromatography, colorless compounds are examined using a locating agent.

It is a chemical that combines with colorless substances to produce colorful compounds that are easy to see for analysis. Ninhydrin spray is an example of a locating agent of this type.

Thus, a locating agent is used in an experiment to separate amino acids by chromatography as it helps in determining colorless substances on paper.

What is the situation when I might travel high velocity but low acceleration
Anna007 [38]
Cruising at 35,000 feet in an airliner, straight toward the east, 
at 500 miles per hour.  

Since your speed is not changing and you're moving in a straight line,
your acceleration is zero.

A sealed can of your favorite soda has a carbon dioxide gas (C0) volume of 0.05 L. When it is refrigerated, the
liubo4ka [24]

Answer:

<h2>0.102 L</h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{207000 \times 0.05}{101000}  =  \frac{10350}{101000}  \\  = 0.102475...

We have the final answer as

<h3>0.102 L</h3>

Hope this helps you
