Pyrotechnic compositions emit light by three basic processes - incandescence (blackbody radiation) atomic emission, and molecular emission.
DNA SEQUENCING is a biochemical process used for determining the order of the nucleotide bases, adenine, guanine, cytosine, and thymine, in any DNA molecule. By comparing the DNA sequence of two organisms, scientists can see if the organisms are related or not, as well as how closely they are related.
The Lewis structure the student drew is incorrect. The total number of electrons in bonds and lone pairs is equal to the total number of valence electrons available, then a valid Lewis structure is produced.
The correct structure is the following:
The structure that was drawn by the student was incorrect because the total number of electrons around Oxygen were incorrect, there were 6 instead of 8, which was against the octet rule. The correct structure should have 8 electrons around each atom.
Answer: 878 kJ of energy is there in cheeseburger
Explanation:
Given : calorific value of fat = 38kJ/g
calorific value of carbohydrate = 17 kJ/g
calorific value of protein = 17kJ/g
1 g of fat contains energy = 38 kJ
7.0 g of fat contains energy = ![\frac{38}{1}\times 7.0=266 kJ](https://tex.z-dn.net/?f=%5Cfrac%7B38%7D%7B1%7D%5Ctimes%207.0%3D266%20kJ)
1 g of carbohydrate contains energy = 17 kJ
25 g of fat contains energy = ![\frac{17}{1}\times 25=425kJ](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B1%7D%5Ctimes%2025%3D425kJ)
1 g of protein contains energy = 17 kJ
11 g of protein contains energy = ![\frac{17}{1}\times 11=187kJ](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B1%7D%5Ctimes%2011%3D187kJ)
Total energy = (266+425+187) kJ = 878 kJ
