Predicting Products

Predict the products for the this Single Replacement reaction:

K + HCl →

• KCl + H₂ because H and K are cations and will switch places.

• KHCl because only one product will be formed.

• KH + Cl₂ because the cations will combine together.

• HCl + K₂ because no chemical reaction occurs.

Predict the products for the this Double Replacement reaction:

AgNO₃ + KCl →

• AgCl + KNO₃ because the cations switch places.

• AgK + ClNO₃ because the cations will combine.

• KAg + NO₃Cl because the anions will combine.

• AgCl + 3 KNO because the 3 is needed to balance the equation.

Predict the products of this single replacement reaction: Na + H₂O →

• NaO + H₂

• NaOH + H₂

• NaH + O₂

• ONaH
