What is the correct balanced equation for the reaction of sodium with water?
Wittaler [7]

Answer:

 A.    2Na       +    2H₂O   →    2NaOH   +  H₂

When sodium is reacted with water, a single replacement reaction occurs. The product of the reaction is typically sodium hydroxide and hydrogen gas.

Reactants:

        Sodium +  water

Product:

        Sodium hydroxide + hydrogen gas

So;

         2Na       +    2H₂O   →    2NaOH   +  H₂

100cm³of a solution of potassium hydroxide contains 0.56g of the dissolved solute. What is the molar concentration of this solut
s2008m [1.1K]

Answer:

[KOH] = 0.10M in KOH

Explanation:

Molar Concentration [M] = moles solute/volume solution in liters

moles KOH = 0.56g/56g/mole = 0.01mole

Volume of solution = 100cm³ = 100ml = 0.10 liter

[KOH] = 0.01 mole KOH / 0.10 liter solution = 0.10M in KOH

Cacodyl, which has an intolerable garlicky odor and is used in the manufacture of cacodylic acid, a cotton herbicide, has a mass
Papessa [141]

Answer:

The molecular formula of cacodyl is C₄H₁₂As₂.

Explanation:

<u>Let's assume we have 1 mol of cacodyl</u>, in that case we'd have 209.96 g of cacodyl and the<u> following masses of its components</u>:

  • 209.96 g * 22.88/100 = 48.04 g C
  • 209.96 g * 5.76/100 = 12.09 g H
  • 209.96 g * 71.36/100 = 149.83 g As

Now we convert those masses into moles:

  • 48.04 g C ÷ 12 g/mol = 4.00 mol C
  • 12.09 g H ÷ 1 g/mol = 12.09 mol H
  • 149.83 g As ÷ 74.92 g/mol = 2.00 mol As

Those amounts of moles represent the amount of each component in 1 mol of cacodyl, thus, the molecular formula of cacodyl is C₄H₁₂As₂.
