It might not exactly spoil with mold and bacteria, but it might have oxidized and changed color and flavor to the extent that it isn't good any more.
You can, but i wouldn't, unless it hasn't been open yet
Only if it is left out a long time to ferment or spoil.
Eventually bacteria will grow and cause it to spoil.
It depends what kind it is first you have to check if there is an expiration date.
It does expire. But it does not spoil, it just weakens.
I don't think so.
yes it dose

No they cant spoil because they're dry products but if you leave them out they will get stale!! Not true. I just ate some crackers that hadn't been opened but had an expiration date of 14 months ago (which I didn't realize until after the fact). They were crispy and appeared okay, but tasted like they were rotting. I smelled them, and there's no doubt there was something growing in them.
no.. because the minerals and vitamins that water has, and plants need, tomato juice doesn't have. besides, it would spoil plant, and blog its roots.
If by go off you mean spoil, then yes, but due to the higher acid content, any pathogen that causes canned tomato juice to spoil is pretty hardy, and if the spoilage occurred before the container is opened, something unsanitary happened during the canning process.
If the juice is within a sealed container, it may last a couple of days before beginning to spoil. If left in an open container, it can begin to ferment within hours, especially in warm weather. Storage in refrigeration or a dark closed space will help to last beyond a week.
