Answer:
The correct answer is option C.
Explanation:
A. The -COOH group would experience hydrogen bonding with water.
The statement is true because , double bonded oxygen atom of carboxylic group interacts with hydrogen atom of water molecule and oxygen atom of water molecule is in same interaction with hydrogen atom of carboxylic acid.
B. The long alkane ''tail" 
, is hydrophobic.
The statement is true because , region which do not interacts with water molecule is termed as hydrophobic region and region which do interacts with water molecule is termed as hydrophilic region. Generally ,alkanes are are hydrophobic in nature so is the alkane chain in stearic acid.
C. Stearic acid and water are probably miscible.
The statement is false because of higher hydrophobic region the interaction between the acid molecules and water molecules results in immiscibility.
D. Stearic acid would probably dissolve in non polar solvents such as hexane 
.
The statement is true because of hydrophobic part in stearic acid is larger so that is why it get easily dissolve in non polar solvents.
E. Stearic acid contains hydrophobic regions
The statement is true because of higher hydrophobic region due to which they easily get dissolved in organic and non polar solvents.
Answer:
Mixing of salt is physical change.
Explanation:
Mixing of salt is physical change because no chemical reaction occur between them. Sand is non polar while salt is polar.
Physical Change:
The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.
These changes were reversible.
They have same chemical property.
These changes can be observed with naked eye.
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Answer:
Species
Explanation:
Species is the group of organisms able to interbreed and produce fertile offspring.
Let's break down each word in the question:
"Organisms" means living thing. It can be a plant or animal like we usually think of, but it also includes the really small single-celled living things like some bacteria.
"Interbreed" means to mate with each other.
"Fertile" means that the living thing can also have babies.
"Offspring" means the children that are born.
"Fertile offspring" means that the children that are made must be able to have babies of their own. For example, if a frog and a bird could interbreed, they might produce offspring (children). But, if those frog-birds cannot also have children, then frog-bird is not a species.
