Question

What’s the reaction types?

treuellons. 1. The first reaction involves reacting aluminum with base to form salt and hydrogen gas. The unbalanced chemical reaction is shown below that the number of each atom on the reactants is equal to the number of each Then identify the type of reaction, keeping in mind that any reaction may be more the Finally, record your observations during this step of the reaction. ning aluminum with base to form a potassium aluminum hydroxide reaction is shown below. Balance the reaction so is equal to the number of each atom in the products. Unbalanced Chemical Reaction Al(s) + KOH(aq) + H,O(l) → KAI(OH),(aq) + H, (g) Balanced Chemical Reaction 2A1 (5) + 2 KOH COG) + 6 H 20(1) - 2 KAICOH)2(aq) + 3 H2(a Reaction Type(s) Cacid-base.gas formation, precipitation,COMBIN OHION decomposition, redox or single displacement ) Observations
