Answer:

8.5gm O2 produced

Explanation:

When heated, KClO3 decomposes into KCl and O2. 2KClO3⟶2KCl+3O2 If this reaction produced 13.2 g KCl, how many grams of O2 were produced?

for every 2 moles of KCl produced, 3 moles of O2 are produced

Mol weight of KCl =39+35.5=74.5gm

13.2 gm KCl = 13.2/74.5 = 0.177 moles

this will make (3/2) X 0.177 = 0.2655 moles of O2

O2 mol wt is 32  0.2655 X32 = 8.5gm O2 produced

In solution, strong acids and bases ionize completely, but weak acids and bases ionize only partially.
Vadim26 [7]

Answer:

The given statement is true.

Explanation:

Strong acids and bases act as strong electrolytes.They undergo complete dissociation in an aqueous medium to generate cations and anions.

   For example HCl ⇄ H+  +  Cl-

Hydrochloric acid is a strong electrolyte,it undergo complete dissociation in an aqueous solution to generate H+ ion and Cl- ion.

On the other hand acetic acid is a weak acid and act as weak electrolyte.In aqueous solution acetic acid under partial dissociation to form acetate anion and proton.

  CH3COOH  ⇄  CH3COO- + H+

PLEASE HELP, I ONLY NEED THE RIGHT ANSWER IN LITERS
grandymaker [24]
You can form 9.20 L of NH₃ gas at 93.0 °C and 37.3 kPa or 2.56 L at STP. The balanced chemical equation is N₂ + 3H₂ → 2NH₃ Since all substances are gases, we can use litres instead of moles in our calculations. You don't specify the pressure and temperature of the NH₃, so I will calculate its volume in two ways.
