Answer:
Quantitative observation is an objective collection of data which is primarily focused on numbers and values.
Answer:
See the answer below
Explanation:
<em>First, it should be understood that an endothermic reaction is one that absorbs energy in the form of heat from the surrounding.</em> The products of endothermic reactions usually have higher energy than their reactants. Hence, the ΔH° which is referred to as the enthalpy change is usually positive.
<u>Forgetting to cover the coffee-cup calorimeter means some of the heat energy absorbed by the reactants would be exchanged back to the surroundings - a loss.</u> It also means that the enthalpy change would be smaller compared to if the cup had been covered because some of the heat has been lost to the surrounding.
Answer:
Project scope statement?
Explanation:
it's good one just do research on it
C. ionization reaction...
THANKS!!
Answer:
In this process, the coffee beans are soaked in caffeine-free green coffee extract, allowing the caffeine to be extracted from the bean and into the solution while the flavor components are retained in the beans. The Swiss Water Process results in coffee that is 99.9% caffeine-free.
Explanation:
Coffee: Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain Coffee species. When coffee berries turn from green to bright red in color – indicating ripeness – they are picked, processed, and dried. Dried coffee seeds are roasted to varying degrees, depending on the desired flavor.
Water: Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients.
