Answer:
pH = 2.4
Explanation:
pH is defined as the negative log of the hydronium concentration.
Thus, we can plug in the given hydronium concentration:
pH = -log[H⁺] = -log[0.0042] = 2.4 (two significant figures)
The pH of the solution is 2.4.
P.S: Although I referred to [H⁺] as hydronium concentration, it is more accurate to express it as [H₃O⁺], though they are interchangeable and means the same thing.
Answer:
C) They all have single covalent bonds.
Explanation:
The given hydrocarbons Butane,Ethane,Methane,Propane belongs to alkane group.
In alkane group consists of hydrogen and carbon in which carbon_carbon bonds are single and carbon_hydrogen bond is also single.
The elements of this group makes bond by sharing of electrons that means they form single covalent bond.
Butane have 4 , Ethane has 2, Methane has 1, and Propane has 3 carbon atoms.
Since they have different number of carbon atoms so their structural formula also differs.
