A teaspoon of the carbohydrate sucrose (common sugar0contains 16 Calories (16 KCal). What is the mass of the teaspoon of the suc
1 answer:
Answer:
3.902 grams is the mass of the teaspoon of the sucrose.
Explanation:
Calories in 1 teaspoon of carbohydrate sucrose = 16 calorie
The average number of calories for the carbohydrates is 4.1 Calories/g
Then number of grams in 1 calorie =
Mass of 16 calories:
3.902 grams is the mass of the teaspoon of the sucrose.

Answer: Option (b) is the correct answer.
Explanation:
A covalent bond is defined as the bond which occurs due to sharing of electrons between the combining atoms.
Generally, a covalent bond is formed between non-metals.
For example, both nitrogen and oxygen atoms are non-metals and they combine covalently to form compound.
As nitrogen has 5 valence electrons and an oxygen atom has 6 valence electrons. So, there occurs unequal sharing of electrons between the two.
Thus, we can conclude that when a covalent bond forms then electrons in valence shells are shared between atoms.
Hi, you've asked an incomplete question. Here's the diagram that completes the question.
Answer:
<u>(B) nonpolar covalent bonds</u>
Explanation:
This structure in the diagram rightly fits the description of a non-covalent bond because there is an equal sharing of electrons of Carbon (C) and Chlorine (Cl).
<em>Remember</em> too that these elements are in their solid-state, hence the CCl4 (carbon tetrachloride) molecules are held strongly together.
