Answer: The empirical formula of vitamin C is
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
The molecular formula of Vitamin C is .
The simplest whole number ratio will be 3: 4: 3 , and thus empirical formula will be .
pOH of a solution = 5.95
<h3>Further explanation</h3>
Given
The concentration of hydronium ions : 8.9 x 10⁻⁹
Required
pOH
Solution
pOH = - log[OH]
[H₃O⁺]= 8.9 x 10⁻⁹
pH = - log[H₃O⁺]
pH = 9 - log 8.9
pH = 8.05
pH + pOH = 14
pOH = 14-pH
pOH= 14-8.05
pOH = 5.95
Answer:
Explanation:The lewis structure of ammonia shows that nitrogen is surrounded by four electron pairs.In term of electron repulsions model,the tetrahedral structure gives maximum separation .There is one lone pair electrons on nitrogen which replels the bonding pairs with the result that angles is reduced from 109 to 107.In term of hybrid orbital.model ,nitrogen utilizes is three of four sp3 orbitals to form sigma bond with three hydrogen atoms having one non bonding orbital on nitrogen.
Answer:
Earth is in the solar system.
Explanation:
Earth is our home and it is in the solar system.
Earth is the fifth-largest of the planets in the solar system and the third planet from the sun. Earth is the only planet having oxygen and water that supports life. Till now according to the research Earth is the only planet having life.
Planets are in the solar system, the solar system is in the milky way and the milky way is present in the universe. T<u>he astronomer identifies our home in the universe as "Earth is in the solar system" as Earth is our home.</u>
Hence, the correct answer is "Earth is in the solar system."
