When trying to balance a chemical equation and it includes a triangle (delta) symbol, does that affect how I balance the equation?

The delta symbol above the arrow in a chemical equation simply indicates that in order for the reaction to take place heat must be applied to the reactants. The delta symbol does not affect how you balance the chemical equation.

Does the introduction of catalysts to assist the reaction change the equation?

The introduction of a catalyst does NOT change the chemical equation. The catalyst only assists in a reaction by lowering the activation energy and making the reaction happen faster. In the one step equations we are looking at the catalyst is not included in the reaction.

When balancing the equations, only the atoms of the molecules that are reactants or products need to be considered. Small symbols that occur on top of the arrow are typically the reaction conditions or catalysts you need in order for the reaction to proceed.

No, you can balance just as you normally would. All these symbols do it keep the integrity of the equation. If these equations were applied in a real lab example, the delta indicates that heat must be added for the reaction to proceed. The idea of these equations is that they can occur in real life, so the equations provide all the information necessary to replicate the reaction.
