Answer:
According to Le Chatelier’s Principle, a stress placed on a system at equilibrium will cause the equilibrium to shift to counteract the stress. For example, a temperature increase in the above reaction will favor the reverse reaction to use the excess heat and form brown NO2 gas. A temperature decrease in the above reaction favors the forward reaction to produce heat and form colorless N2O4 gas.
Answer:
The answer to your question is the first option
Explanation:
Just remember that to balance using this method,
first look for the elements that change their oxidation number, and
later count the number of electrons that changed,
later identify which element oxidazes and which reduces and
finally cross the number of electrons that change in each semireaction and write these numbers in the main reaction.
2Cr⁺³ (aq) + 6Cl⁻ (aq) ⇒ 2Cr(s) + 3Cl₂ (g)
2 Cr 2
6 Cl 6
Plants combine water and Carbon dioxide from the air to make glucose for themselves, and giving off oxygen in the process. So CO2 and H2O would be on ther reactant side (left) with O2 and C6H12O6 being on the product side (right).
