On food labels, we can read the food-calories of the product. The food calorie is written as “Cal” and it corresponds to 1,000 calories with the lower case ‘c’. In summary, one food-calorie = 1 kcal = 1 Cal = 4,186 Joules
How many Joules will be released by combustion of 1 kg of rice, if rice has 3,200 food-calories per kilogram? Show your work.

Solutions

Expert Solution

1 food-calorie =1 kcal =1 Cal =4186 Joules

So, energy released by combustion of 1 kg of rice = 3200 food-calories

                                                                         = 3200 x 4186 Joules

                                                                         = 13.3952 x 106 Joules

You have been asked to experimentally determine the Calorie (1 Calorie = 1000 calories) values of various desserts. You realize that a combustion reaction is analogous to the digestive reaction occurring during metabolism and the amount of energy released from combustion will tell us how much nutritional energy we can expect from the food. You then need to apply the principles of calorimetry to measure the energy released by the desserts upon combustion. After some research, you discover that calorimetry...

A study was undertaken to see how accurate food labeling for calories on food that is considered "reduced calorie". The group measured the amount of calories for each item of food and then found the percent difference between measured and labeled food. The group also looked at food that was nationally advertised, regionally distributed, or locally prepared. The data is in the following table ("Calories datafile," 2013). Table: Percent Differences Between Measured and Labeled Food National Advertised Regionally Distributed Locally...

A study was undertaken to see how accurate food labeling for calories on food that is considered reduced calorie. The group measured the amount of calories for each item of food and then found the percent difference between measured and labeled food, (measured ! labeled) labeled *100%. The group also looked at food that was nationally advertised, regionally distributed, or locally prepared. The data is in table #11.3.5 ("Calories datafile," 2013). Do the data indicate that at least two of...
