If grey water is left unused for too long it evaporates and then causes sicknesses so the water should go to the sewer.
If unused chemicals are not poured back into their containers, they will be wasted. Also, they could be dangerous and should not be left lying around.
Unused TTL inputs should never be left open. Depending on how their logic levels will affect the operation you want from the device, unused inputs should always be tied to either the +5v supply (logic 1) or to the circuit ground (logic 0). If an input is left open ("floating"), then it can assume either logic level, and you literally never know which state it's in.

sorry but i cannot say but i have 12 unused codes. 1 i have used and left is 11
Are you sure it is unused? Indy tickets had added tear-offs on the left side that are very uncommon. If unused, about $100
No, canned cat food should not be left out for more than 2 hours to prevent bacterial growth and spoilage. It is best to refrigerate any unused portions promptly.
The beef goes off, probably turning grey and swelling a bit due to osmosis. the water level will go down through evaporation and osmosis, what's left will also turn grey and probably have a greasy film. The whole thing will smell.
we should save water because there is only 3% of fresh water left and most of it is in glaciers
The hot water line should be connected to the left and the cold water line should be connected to the right for proper functionality.
Turn the faucet handle to the left to get hot water.
It may be caused by other unused drains in the house. I experienced this after I became the only person living in my house & two sinks, two toilets & a shower were unused for a year. The plumber explained that not using drains allows the water left in the trap to evaporate & that allows sulphur odors to be released from the toilet that is being used. The solution is to pour some water down each unused drain once/week so there is always some water in the trap. That water blocks odors from escaping.
salt and water. let the water evaporate and the salt should be left behind.
