In an aquarium the water quantity is limited and fish excrete ammonia through their gills and body, this dissolves in water and creates toxins.
<u>Explanation</u>:
- In an aquarium the water quantity is limited and fish excrete ammonia through their gills and body, this dissolves in water and creates toxins. Over some time some bacteria develop in water which converts this ammonia into nitrites and then into nitrates. Till this process is complete, the aquarium remains a death trap.
There are some reasons for a fish to die early,
- This one is common for beginners. They don’t have any idea about the nitrogen cycle. And they simply buy a fish tank and fish on the same day, go home and set it up.
- Ammonia spikes - Even in a cycled tank, you can have occasional ammonia spikes due to overfeeding. Incompatible tank mates - If you put a too docile fish with a very aggressive cichlid, it will get harassed and eventually die due to stress.

Answer:
400.197mmHg
Explanation:
P1V1 / T1 = P2V2 / T2
Where P1=524 mm Hg V1 =275 ml T1 = 35°C +273 = 308k
V2= 325-ml T2= 5°C+273 = 278k , P2= ?
Substituting the values into the formula.
524 mm Hg ×275 ml /308k = P2×325-ml/278k
Cross multiply
524 mm Hg ×275 ml×278k=308k×P2×325-ml
40059800= 100100×P2
P2 = 40059800/100100
P2= 400.197mmHg
Hence, the second pressure will be 400.197mmHg
