Sagot :

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.
