What will be the effect of using hot water instead of ice in distillation?
Using hot water instead of ice in distillation may affect the separation process by altering the temperature and vapor pressure relationship. The use of hot water can increase the rate of vaporization of the components being separated and potentially lead to loss of separation efficiency. Additionally, it may also impact the purity of the distillate obtained.
Is chloride mined?
Chloride is not mined directly; instead, it is usually extracted as a byproduct during the mining of other minerals, such as salt (sodium chloride). It can also be obtained from the extraction of brine from saltwater sources such as salt lakes and underground salt deposits.
Why alkali and alkaline earth metals cannot be obtained by chemical reduction method?
Alkali and alkaline earth metals are highly reactive elements that readily form compounds with other elements. This high reactivity makes them difficult to isolate using chemical reduction methods as they will easily react with any available substance, such as water or oxygen, preventing pure elemental form from being obtained. Instead, alkali and alkaline earth metals are typically extracted through more complex methods, such as electrolysis or by using reactive metals like magnesium as reducing agents.
What made alchemy unscientific in its pratices?
Alchemy was unscientific due to its reliance on mystical and spiritual elements, such as the belief in transmutation of base metals into gold through esoteric means. Additionally, alchemy lacked a systematic and empirical approach to experimentation, instead relying on secrecy and symbolism. As a result, alchemy did not follow the principles of modern scientific inquiry based on observation, experimentation, and reproducibility.
Which elements are found in calories?
"Calorie" is not a chemical name but instead is a unit of the energy value that be obtained from food. Since any food sufficient to sustain life can provide calories for energy to the organism that consumes the food, almost any element (except the noble gases) can be a source of calories, but a calorie is a unit of the abstract concept energy rather than a material substance and therefore can not be "found" in food in the usual meaning of that phrase.
Why must the zero kelvin value be obtained by extrapolation instead of direct observation?
Because it can never be physically achieved, so there's nothing to observe. Even intergalactic space is warmer than zero Kelvin ... (as if you could fly a thermometer out there to observe it).
What does visceral mean in medical term?
Internal organs are collectively called the Viscera (vis' er-ah; viscus = an organ in a body cavity) or Visceral organs. The Viscera covers and lines hollow organs in the body.
Which type of historical document is based on interpretation of other documents instead of direct observation?
Secondary source
What type of observation is a non-numerical description?
A non-numerical description is a qualitative observation. It uses words to describe qualities or characteristics of an object, event, or phenomenon instead of numerical data.
What words to use instead of got?
Some words to use instead of got are Get, Gotten, Getten, have, had!
What is another word you can use instead of fromality?
Meaningless,Regulation or act,Formal,Rigid observation of rules and regulations,
What does qualitative observation mean?
A Qualitative observation is an observation that is found using data without numbers. (hence the term quality instead of quantity which is quantitative) Ex: the dog is brown This orange has a peel People har hair
How will the values of the current obtained vary if the second source is connected in the middle section of the circuit instead?
thanks for the answer
Can a scientific theory be proven?
No, a scientific theory cannot be proven. Instead, it is supported by evidence and can be further validated through experimentation and observation.
Which type of historical documents is based on interpretation of other documents instead of direct observation?
The declaration of independence is primary source
Why is it important for a scientist to be open-minded but skeptical?
It is important for a scientist to be open minded but skeptical so that he/she will gather the information on a direct observation instead of on a feeling.
Who was the first pre socratic philosopher to use observation and reasoning in the study of?
Thales of Miletus is often credited as the first pre-Socratic philosopher to emphasize observation and reasoning in the study of nature. He sought natural explanations for phenomena instead of relying on mythological explanations.
