Answer:

Both have a pH greater than 7, but NH₃ has a lower pH than KOH.

Explanation:

  • Both of NH₃ and KOH are bases (can produce OH⁻), so both have a pH greater than 7.
  • NH₃ is considered as a weak base (not completely ionized), while KOH is a strong base (completely ionized).
  • If both NH₃ an KOH has the same concentration, KOH produces OH⁻ higher than that of NH₃.
  • So, NH₃ has a lower pH than KOH.

  • Thus the right choice is:

<em>Both have a pH greater than 7, but NH₃ has a lower pH than KOH.</em>

The amine here is the easiest to spot since there’s only one structure that has a nitrogen atom, which would be the first (the first structure is a primary amine).

The distinguishing functional group of an alcohol is the hydroxy group (—OH). Both the second and third structures have an —OH group, but the —OH in the third structure is part of a carboxyl group (—COOH or —C(=O)OH). A carboxyl group takes priority over hydroxy group. Thus, the second structure would be an alcohol and the third structure would be a carboxylic acid.

That leaves us with the fourth structure, a hydrocarbon with a halogen substitutent, or, aptly named, a halocarbon.

Suppose hydrochloric acid reacts with potassium sulfite yielding water, sulfur dioxide, and potassium chloride. Suppose 4 moles
anzhelika [568]

Answer:

128 grams of sulfur dioxide are produced.

Explanation:

2HCl+K_2SO_3\rightarrow SO_2+2KCl+H_2O

Moles of HCl = 4 moles

According to reaction, 2 moles of HCl gives 1 mole of sulfur dioxide gas.

Then 4 moles of HCl will give:

\frac{1}{2}\times 4 moles=2 moles of sulfur dioxide gas.

Mass of sulfur dioxide gas = 2 mol × 64 g/mol = 128 g

128 grams of sulfur dioxide are produced.

How does the molecular formula of a compound differ from the empirical formula? Can a compound’s empirical and molecular formula
Y_Kistochka [10]
Molecular is every element present in the compound eg C2H6, empirical is the smallest whole number ratio of elements in a compound so that would be CH3 as you divide by the highest common factor. Some compounds only have 1 formula if they are simple or have no common factors. Eg methane, CH4 is its molecular and empirical because its the simplest whole number ratio and includes every element in the molecule
