We know that the oxygen (O2) causes a glowing splint to reignite, however, let us check what is missing on the products side of the chemical equation: <span>
KBrO3 → KBr + ? 
As we see, oxygen (O2) is the element missing from the other side. Therefore the balanced chemical equation for this decomposition is as follows: </span>
<span>2KBrO3 → 2KBr + 3O2 </span>

Otrada [13]

During a neutralization reaction phosphoric acid reacts with potassium hydroxide to produce potassium phosphate and water, the reaction occurs with a 64.9% yield.

A neutralization reaction is a chemical process in which an acid and a base combine to produce salt and water as the end products. In a neutralization process, a mixture of H+ ions and OH- ions results in the formation of water.

Potassium phosphate and water are created when potassium hydroxide and phosphoric acid combine. The reaction's balanced equation is as follows: K3PO4(aq) + 3H2O = 3KOH(aq) + H3PO4(aq) (l) If six moles of potassium hydroxide react, phosphoric acid is used in the reaction.

A. 20 moles of NH3 are needed to produce how many moles of H2O?
tiny-mole [99]

a. 30 moles of H₂O

b. 2.33 moles of N₂

<h3>Further explanation</h3>

Given

a. 20 moles of NH₃

b. 3.5 moles of O₂

Required

a. moles of H₂O

b. moles of N₂

Solution

Reaction

4NH₃+3O₂⇒2N₂+6H₂O

a. From the equation, mol ratio NH₃ : H₂O = 4 : 6, so mol H₂O :

=6/4 x mol NH₃

= 6/4 x 20 moles

= 30 moles

b. From the equation, mol ratio N₂ : O₂ = 2 : 3, so mol N₂ :

=2/3 x mol O₂

= 2/3 x 3.5 moles

= 2.33 moles

Equal amounts of N2 and O2 are added, under certain conditions, to a closed container. Which changes occur in the reverse reacti
geniusboy [140]
1) The forward reaction is N2 (g) + O2 (g)  → 2NO

(that reaction requires special contitions because at normal pressures and temperatures N2 and O2 do not react to form another compound.

2) The equiblibrium equation is

  N2 (g) + O2 (g)  ⇄ 2NO

3) Then, the reverse reaction is

2NO → N2(g) + O2(g)

Answer: 2NO → N2(g) + O2(g)
