Answer:
His mistake was that he also gave the plants in the music room some fertilizer
Explanation:
When carrying out a reliable experiment, the only variable should be the question being tested. The question here is whether playing music for plants helps them grow faster. Therefore, all the plants should be grown in exactly the same conditions apart from the presence or absence of music.
However, Jo also added fertilizer to the plants in the room where music was playing. Therefore, we don't know whether the fertilizer or the music caused the plants to grow faster.
Instead, Jo should have not given fertilizer to any of the plants, or given fertilizer to all the plants.
I think the effect of increasing temperature would be; the equilbrium will shift back wards. Increase in temperature favors backward reaction since the forward reaction is exothermic and the backward reaction is endothermic. Therefore, the equilibrium will shift back wards, and there will be more reactants (H2 and Cl2) compared to the products
This is the water cycle and the process is Evaporation.
The reaction will generally form more reactants than products.
