It would take a lot of coffee for a 200 pound person to reach LD 50. The more the weight the more it takes.
The ld50 for humans varies depending on sensitivity of the person- between 150 and 200 mg per kilogram of weight. Using the lower value, that would be over 68 of the 12 oz cups in a very short period of time. Unlikely to happen, as ingestion of 6.3 GALLONS of coffee in a short time frame (half hours) is almost impossible.
No, when you mix coffee with water to make a cup of coffee, the coffee itself is not considered an impurity. The coffee grounds are the main ingredient and the water is used as a solvent to extract the flavor and caffeine to create the beverage. Impurities would refer to any other foreign substances present in the mixture that are not part of the intended coffee drink.
no !!!!!!!!!!!!!!!!!!! i don't drink coffee
Coffee contains a variety of chemical elements, but the main ones are carbon, hydrogen, oxygen, nitrogen, and trace amounts of minerals like potassium, magnesium, and phosphorus. These elements contribute to the flavor, aroma, and chemical composition of coffee.
Caffeine is actually a non-polar substance, and normally would not dissolve in water, but since it contains some polar bonds it is able to dissolve in hot water. This is how they decaffeinate coffee, the coffee beans are soaked in hot water and all the flavoring, caffeine and aroma are extracted. Then it is put through a carbon filter which holds back all the caffeine so the flavoring and aroma can be added back into the bean, roasted, and ground to make you morning cup of decaffeinated coffee!

Need the high from the caffeine
The answer to your question, What's a stimulant found in tea, cola, chocolate, and coffee?' The answer would be caffeine. Yes I am sure this is the answer. It truly is I know for sure! That is why most people drink coffee, tea, or cola in the morning and why people love chocolate so much.caffeine
NO why would they - unless you pour coffee on them.
The "boost" from coffee comes from the caffeine. The answer would be Yes. Regular coffee gives your metabolism a bigger boost than decaffeinated coffee. The average mg's of caffeine in an 8 ounce cup of regular coffee is about 100mg. Decaf coffee is not caffeine free and contains from 15 to 20 mg of caffeine in an 8 ounce cup
On average coffee, but that is not to say that tea does not have caffeine. Tea USA brands per 8 oz has about 40 mg Drip coffee has about 115-175 mg Just to add a little more to this answer: If you were to measure the amount of caffiene in tea leaves and coffee beans you would find more caffeine in tea but the way coffee beans are processed and ground means that more of the caffeine from coffee gets into the drink. To summarise: If you are talking about the drink: Coffee generally has more caffeine If you are talking about the plants: Tea generally has more caffeine.
There're 90-105 mg of caffeine in 8oz of coffee. The body retains up to 300mg at any time. Of course that depends on how fast you drink the coffee, and how fast you can detox it. Depending on the person, it would last in the body 4-6 hours.
Yes, unless it is made with decaffeinated coffee (which isn't as common). The ice or cold temperature would not affect the amount of caffeine present. However, the caffeine in iced coffee may not take effect as quickly as hot coffee so the onset of the affects might be less abrupt and, therefore, less noticeable.

What I would say is to drink as much as you want. Though because coffee has caffeine in it that can be bad for your body.
no. coffee contains another drug called caffeine. caffeine is much less addictive than nicotine and has far fewer negative side affects. Caffeine can cause addictions though. If a person of any age were to drink at least one cup of coffee for many weeks in a row, they would experience withdrawal symptoms if they suddenly stopped. those symptoms include headaches, nausea, irritability and sluggishness.
A Cup of Black Coffee has much more caffeine. ^^ Are you stoned, or just stupid? Why in HELL would adding milk and sugar decrease the content of a chemical present since BEFORE the coffee was prepared? If you spill some out to make room, sure there'd be less caffeine - but the difference in volume is barely perceptible.
