The missing component is Cl₂.
The missing component is CO₂ + 2H₂O.
1. The following can be used to present the reaction:
? + 2NaBr → 2NaCl + Br₂
Both 2 Na and 2 Br are present on the reactant side, whereas 2 Na, 2 Br, and 2 Cl are present on the product side.
So the missing component is Cl₂.
2. The following is a presentation of the possible reaction;
CH₄ + 2O₂ → ?
The elements in the reactant side of the reaction are 1 Carbon, 4 hydrogen and 4 oxygen.
The elements in the product side are missing.
Therefore;
The the missing elements in the product are, 1 Carbon, 4 hydrogen and 4 oxygen. which gives;
The missing component = CO₂ + 2H₂O.
So, the missing components for reaction 1 is Cl₂ and for reaction 2 is CO₂ + 2H₂O.
