The correct answer is Period B. Exponential growth is an increase in size at a constantly growing rate. Period A appears to be linear growth, Period C is no growth at all and Period D is exponential decline.
Answer: beta, gamma, alpha
Explanation: Beta is weakest gamma is middle alpha is strongest
Answer: Thus
is a secondary alkanol.
Explanation:
Alkanol are compounds which contains carbons bonded by single bonds and contains hydroxy (-OH) as functional group.
Primary alkanol are those compounds which contain hydroxyl group attached a carbon which is further attached to a single carbon atom. Example:
and 
Secondary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to two more carbon atoms.Example:
Tertiary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to three more carbon atoms. Example: 
Thus
is a secondary alkanol.
Answer:
Mass = 4.44 g
Explanation:
Given data:
Number of moles of Ne = 0.220 mol
Mass in gram = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of Ne = 20.2 g/mol
by putting values,
0.220 mol = mass/ 20.2 g/mol
Mass = 0.220 mol × 20.2 g/mol
Mass = 4.44 g
CO2 contains one atom of carbon and two atoms of oxygen.
The molecule is called Carbon dioxide, indicating that it is covalent and that there are two oxygen present.
