Answer:
The answer to your question is below
Explanation:
A.
[H₃O⁺] = 2 x 10⁻¹⁴ M
pH = ?
Formula
pH = - log [H₃O⁺]
Substitution
pH = - log [2 x 10⁻¹⁴]
Result
pH = 13.7
B.
[H₃O⁺] = ?
pH = 3.12
Formula
pH = - log [H₃O⁺]
Substitution
3.12 = - log [H₃O⁺]
![10^{-3.12} = [H_{3} O^{+}]](https://tex.z-dn.net/?f=10%5E%7B-3.12%7D%20%3D%20%5BH_%7B3%7D%20O%5E%7B%2B%7D%5D)
Result
[H₃O⁺] = 7.59 M
Answer: Extinction
Animals on the verge of extinction are considered endangered species. Some could argue that the phrasing "threatened" is synonymous to "endangered". Some classify extinction based on if the species is completely wiped out in the wild, or if the species is completely gone (both in the wild and in zoos for instance). Extinction events are not solely due to the changes in atmosphere, but also due to lack of food or habitat, among other possible factors.
Answer:
Lipids.
Explanation:
Steroids are known as the type of lipid which consists of 4 rings of carbon atoms. All steroids have 1 five-sided carbon ring and a 3 six-sided carbon ring. They are works as a hormone in the body and secreted by the ovaries and testes.
Steroids differ in functional groups. When this functional group attached to the steroid ring it gives steroids with a different function. They are composed of largely carbon, and hydrogen atoms. They are insoluble in nature in water.
Answer:
Ethane can be converted into 1- butanol in 4 different steps and reactions.
Explanation:
Step 1 : Ethane follows Markovnikov's rule and reacts with a protic acid called Hydrogen chloride to form Chloroethane.
Step 2: Chloroethane undergoes Wurtz reaction where it reacts with sodium metal in the presence of dry ether to form an higher alkane called butane.
Step 3: Butane undergoes chlorination where it reacts with an halogen called chlorine to form 1-chlorobutane.
Step 4: 1-chlorobutane reacts strong aqueous Potassium hydroxide (KOH) to form 1-butanol.
Attached to this answer is the handwritten conversion of Ethane to 1-butanol showing all the reagents and molecules synthesized along the way.
