Yes, lithium is stable at STP. That doesn't mean it is safe to handle, nor does it mean it remains stable after contacting other other halide salts, or even water (try that one; it will be good). In a nut shell, yes, lithium is stable at 30 degrees Celsius *******AS LONG AS IT'S BY ITSELF******* Look at MSDS for lithium http://www.sciencelab.com/xMSDS-Lithium-9927559
how does enzymes in your body make chemical reactions occur at safe temperature
It depends on the food. To be extra safe over 200 degrees
This depends on the temperature and the fluid.
R-600a but not safe
Within 10 hours
yes, as long as it is cooled to room temperature before freezing.
If it is in a bottle with cap at 23 C one week
So long as it was kept at room temperature, it should be fine to eat after it was left out overnight.
No. That is too long to leave potentially hazardous food sitting at room temperature.
The ideal temperature of your room should be between 68-71o F You should not go below 50o or above 82o F.
4 hours is the magic number taught at all food handling courses.
Beef jerky is filled with preservatives that keep it healthy despite the room temperature condition it's kept in.
Cooked meat should not be left at room temperature for more than 2 hours. At that point, it should be refrigerated or reheated. Cooked meat should be cooled at room temperature for an hour then refrigerated. After 2 hours it is not considered safe at room temperature. Food needs to be kept above 140F AFTER being heated to AT LEAST 160F.
Yes
Depending on how long they are or were left at room temperature. Bacteria begins to grow on foods left out at room temperature after just one hour. The longer left out the more chance of bacteria.
I would assume it would be safe, but keeping in a cool place would be ideal
