Brrunno [24]3 years ago

Since there are 23 days and 24 hours in each day, you multi-ply them and get 552 hours. Since each hours is 60 minutes, 552*60 is 33120 minutes. Since one minute is 60 seconds, 60*33120 is 1,987,200 seconds. Therefore, there are 1,987,200 seconds in 23 days.

How does the calorie compare to the metric unit the joule? How do you calculate a calorie? Is it the same for all types of food?
wlad13 [49]

Calorie (cal) or small calorie, is the amount of energy needed to heat one gram of water by one degree Celsius.

One small calorie is approximately 4.2 joules.

A calorie is a unit of energy.

For example:

Q = 150000 J; released energy.

Convert Jules in calories:

Q = 150000 J ÷ 4.186 J/calorie.

Q = 35833.73 calorie.

The large calorie or nutritional calorie (symbols: Cal, kcal) is the heat energy needed to raise the temperature of one kilogramof water by one degree Celsius.  

A nutritional calorie, or kilocalorie, is equal to 1000 calories.

One large calorie is 4.184 kilojoules: 1 Cal = 4.184 kJ.

For example:

E = 2500 Cal; energy burnt.

E = 2500 Cal · 4.184 kJ/Cal.

E = 10460 kJ.

All of the following are examples of allotropes of carbon EXCEPT Choose the one alternative that best completes the statement or
Leona [35]

Answer:

quartz

Explanation:

<em>The correct option would be </em><em>quartz.</em>

<u>Allotropy is a phenomenon that describes the natural existence of the same element in different forms with different physical characteristics. Allotropes are therefore different forms of the same element.</u>

Carbon as an element has several allotropes which include diamond, graphite, graphene, amorphous carbon, and fullerenes. Quartz is a crystalline solid that is composed of silicon dioxide and not carbon.

Hence, all the options are carbon allotropes except quartz.
