If your choices are the following: A.Neutrons released during a fusion reaction cause other nuclei to fuse.
B. Neutrons released during a fission reaction cause other nuclei to split.
C. Helium nuclei released during a fission reaction cause other nuclei to split.
D. Helium nuclei released during a fusion reaction cause other nuclei to fuse.
Then the answer is B. In fission, the nuclei is splitted and releases neutrons causing another chemical to form.
Answer:
C₆H₅COOH Benzoic Acid
Explanation:
Here we are using the extraction method to separate benzoic acid from naphtalene in the ether solution by reacting it with the base sodium bicarbonate to produce the salt sodium benzoate ( naphtalene remains in the organic layer ) .
The sodium benzoate is completely soluble in the aqueous layer being a salt, and reacts with hydrochloric acid ( again an acid base reaction ) which precipitates the benzoic acid since the it is insoluble in water hence separating it.

There are few reasons <span>why mercury is used in liquid barometer instead of water:
1. </span>Mercury (13.69 g/cm³) is more dense than water (1.00 g/cm³), so if we use water in barometar, <span>length of barometer would be much longer.</span><span>
2. </span><span>Mercury has lower vapor pressure than water.
3. </span>Mercury has lower freezing point (-38.83°C) than water (0°C)<span>.
