"In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms. ... In fact, in certain extreme environments, such as neutron stars, extreme temperature and pressure prevents atoms from existing at all."
This is an Engineering question, and the answer is reasonably simple. The mechanical advantage is given by:
MA =
on a lever or ramp system.
MA =
MA = 6.67 (there are no units, as MA is a ratio)
Answer: Neutral Value
Explanation: pH of the blood is maintained at 7.0 to 7.5that is neutral value.
This is because if the pH of the is lower than the maintained value then it will become acidic .
Acidic pH can cause the medical urgency known as acidosis leading to vomiting, diarrhea etc.
If the pH becomes higher, then the blood will become basic in nature and it can also leas to the death of the person.
That is why the pH of the blood is maintianed at neutral value of 7.0 to 7.5
1 mole ------------- 22.4 L ( at STP )
?? mole ---------- 12 L
12 x 1 / 22.4 => 0.5357 moles
