The circulatory system works with the digestive system. Once the food is digested, the circulatory systems absorb and uses the nutrients in the food. If the digestive system were to break down, the circulatory will not have the nutrients it needs to sufficiently run the body.
It's B) electrons, is the right answer
Given:
P = 123 kPa
V = 10.0 L
n = 0.500 moles
T = ?
Assume that the gas ideally, thus, we can use the ideal gas equation:
PV = nRT
where R = 0.0821 L atm/mol K
123 kPa * 1 atm/101.325 kPa * 10.0 L = 0.500 moles * 0.0821 Latm/molK * T
solve for T
T = 295.72 K<span />
Answer:
Protons
Explanation:
Protons are the subatomic particle that determines the identity of an element.
Answer:
E) rate of appearance of C = 0.45 M/s
rate of the reaction = 0.15 M/s
Explanation:
2A + B → 3C
Writing rate law for the reaction:
<u>Rate of reaction</u> = -
![\frac{d[A]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BA%5D%7D%7Bdt%7D)
= -![\frac{d[B]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BB%5D%7D%7Bdt%7D)
= 
![\frac{d[C]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BC%5D%7D%7Bdt%7D)
→ equation 1
Given that the rate of disappearance of A is 0.3 M/s
⇒ - = 0.3 M/s
⇒Rate of reaction = - = ×0.3 M/s
⇒<u>Rate of reaction = 0.15 M/s</u>
From equation 1, = - 
= ×0.3 M/s
⇒ = 0.45 M/s
or <u>the rate of appearance of C = 0.45 M/s</u>
