The answer is F-1since it is gaining therefore you can take this as electron affinity.

Answer: Option (a) is the correct answer.

Explanation:

When an atom or element gains an electron then the atom acquires a negative charge whereas when an atom or element loses an electron then it acquires a positive charge.

for example, atomic number of fluorine is 9 and when it gains one electron then fluorine atom acquires a negative charge. Hence, neutral atom of fluorine changes into $F^{-1}$ ion.

Thus, we can conclude that $F^{-1}$ ion is formed when an atom of fluorine (F) gains one electron.

Genrish500 [490]

Moss can grow abundantly in an environment with favorable conditions. They usually grow abundantly in cool, moist and dark places. If not dark, they prefer shady areas. Also, they tend to grow in acidic soil with pH range between 5.0-5.5.

timama [110]

Answer:

pI = 6.16

Explanation:

The pI is given by the average of the pKas that are involved. In this case,

Pka of carboxylic acid was given as 2.72 and that of the Amino group was given as 9.60. the average would then be ½(2.72+9.60)

= 6.16

How many moles of calcium carbonate-CaCO3 = 4.15 g

marin [14]

Answer:

Number of moles = 0.042 mol

Explanation:

Given data:

Number of moles = ?

Mass of calcium carbonate = ?

Solution:

Formula:

Number of moles = mass/ molar mass

now we will calculate the molar mass of calcium carbonate.

atomic mass of Ca = 40 amu

atomic mass of C = 12 amu

atomic mass of O = 16 amu

CaCO₃ = 40 + 12+ 3×16

CaCO₃ = 40 + 12+48

CaCO₃ = 100 g/mol

Now we will calculate the number of moles.

Number of moles = 4.15 g / 100 g/mol

Number of moles = 0.042 mol
