Introduction:
Elements combine to form compounds. Compounds have unique characteristics. They are formed from specific combination of elements in a fixed ratio. The force that holds the atoms together in a molecule of a compound is called
Answer to Problem 1STP
Correct answer :
The correct answer is option C. CF4
Explanation of Solution
Explanation/justification for the correct answer:
Option C. CF4−Carbon has four electrons in its outermost shell and fluorine has seven electrons in its outermost shell. Onecarbon atom can share electrons with four different fluorine atoms to complete its outer energy level. It forms four covalent bonds, one with each fluorine atom.Hence one carbon atom can combine with four fluorine atoms to form a compound CF4.
Hence this is the correct option.
Explanation for incorrect answer:
Option A. CF2−One carbon atom can share electrons with four different fluorine atoms to complete its outer energy level. It forms four covalent bonds, one with each fluorine atom. Hence one carbon atom can combine with four fluorine atoms to form a compound CF4. Carbon cannot satisfy outer energy level with only two fluorine atoms.
Hence this is not the correct option.
Option B. CF3- One carbon atom can share electrons with four different fluorine atoms to complete its outer energy level. It forms four covalent bonds, one with each fluorine atom. Hence one carbon atom can combine with four fluorine atoms to form a compound CF4. Carbon cannot satisfy outer energy level with only three fluorine atoms.
Hence this is not the correct option.
Option D. CF5- One carbon atom can share electrons with four different fluorine atoms to complete its outer energy level. It forms four covalent bonds, one with each fluorine atom. Hence one carbon atom can combine with four fluorine atoms to form a compound CF4. Carbon cannot combine with five fluorine atoms.
Hence this is not the correct option.

In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forward

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references.
