Question

Question 6 (1 point) A student is adding NaOH to bring the pH of grape juice up above 10.0 As she adds more and more NaOH, the pH changes are very minimal. What should she do? Give up, as the pH should change quickly Use HCl instead of NaOH, so the pH rises more quickly Continue on the pH will not change until the buffering capacity of the juice has been saturated Double the amount of NaOH she is using Question 7 (1 point) Proteins and carbohydrates have the same caloric content, ounce for ounce. True False Question 8 (1 point) Which food source carries the highest energy content per weight? O protein O carbohydrates O vitamins O fats Question 9 (1 point) Raw sugar and honey have fewer calories than table sugar True False Question 10 (1 point) A food has 5 g of protein, 5 g of carbohydrate and 1 g of fat. What is the calorie distribution? O 1% fat, 5% protein, 5% carbohydrate 40% fat, 40% protein, 20% carbohydrate 20% fat, 40 % protein, 40% carbohydrate O 10% fat, 45% protein, 45% carbohydrate

Answer 1

Ans 6: continue on, the ph will change after the buffering capacity will get saturated

Ans 7: True as calorie content for protein and carbohydrate is the same that is 4 calorie for 1g

Ans 8: The energy density is the term used for energy content per weight so

fat has 9 calories per gram of weight as compared to carbohydrates, protein and vitamins

Ans 9: Raw sugar (4 calories per gram of weight)+ Honey(3.04 calories per gram weight) = 7.04 calories

Table sugar (3.87 calories per gram of weight)

so the ans is false

Ans 10: protein: for 5g has 20 calories

cabohydrate for 5g has 20 calories

fat for 1g has 9 calories

so the proportion for protein:carbohydrate: fat is approximately 1:1:2 which in options is 40: 40:20
