2. How does the director develop the tense, awkward mood during the scene in which
I am Lyosha [343]

Answer:

When reunited with Daisy, Gatsby is at first extremely nervous. He even takes a walk in the rain before she arrives. He arranges everything (the flowers all over Nick's house), but is convinced that the reunion was a mistake. Nick leaves the two of them alone, and when he returns, finds them in a rather happy mood. There is also a change of the weather - the sun is shining outside. The three of them then go to Gatsby's house, where he later reveals Daisy his ritual of staring at the green light and thinking about her.

A chemistry laboratory assistant noticed labels missing from the two reagent bottles containing hydrochloric acid and sodium hyd
aksik [14]

Answer:

Hydrochloric acid (HCL) is an acid, while sodium hydroxide (NaOH) is a base.

In this case the two labels are missing, one method to differentiate them is by mixing each reagent with a base. Let's say we mix sodium carbonate(Na2C03) which is a base with each of the reagent, the sodium carbonate will likely react with Hydrochloric acid which is an acid to form NaCl and H2O, but it will not react with sodium hydroxide which is a base.

Therefore, by mixing the each reagent with a base, we could help place the correct label.

Another way to place the labels correctly is, the bottle containing hydrochloric acid will be sticky while the sodium hydroxide will be slippery. It is a known fact that acids are generally sticky while bases are slippery when touched.
