First you calculate the concentration of [OH⁻] in <span>solution :
POH = - log [ OH</span>⁻]
POH = - log [ 0.027 ]
POH = 1.56
PH + POH = 14
PH + 1.56 = 14
PH = 14 - 1.56
PH = 12.44
hope this helps!
Herd behavior in elephants ensures that individuals are protected and the species is perpetuated.
<h3>What is her behavior?</h3>
It is a behavior that is characteristic of animals that form herds.
Herds generally refer to groups of animals that live or move together or both.
By protecting individual elephants that are weak or young from being preyed upon by lions and leopards, more members of the population survive.
When more members of the population survive, the species is perpetuated and the likelihood of going into extinction reduces.

(d) Sulfur hexafluoride, 
In this compound, there are two types of elements present sulfur and fluorine. There are 1 atom of sulfur element and 6 atoms of fluorine element.
Answer: combustion reaction.
Explanation:
Gasoline is a mixture of hydrocarbons (with some other dded substances in minor proportion).
Assuming a hypothetical composition of the gasoline as C₅H₁₂ (only for explanation purposes), the chemical reaction that occurs when gasoline is burned is represented by:
- 2C₅H₁₂ + 16O₂ → 10CO₂ + 12H₂O + energy.
Combustion is a special type of chemical reaction, in which oxygen combines with other substance (element or compound) releasing a large amount of energy in the form of heat and light. It is a very common reaction of the hydrocarbons and the products are carbon dioxide and water in the form of vapor.
The combustion of carbon (C) is a very important and common reaction that has been using to produce energy: C(s) + O₂(g) → CO₂ (g)
