Answer: The correct answer is a) Acetylcholine.
Explanation:
The acetylcholine is a very important neurotransmitter involved in the mediation of synaptic activity between neurons. Among its most important functions we find: expression of mood states, vasodilation, gastrointestinal motility, bronchoconstriction, circular iris muscle contraction and sweat gland secretion.
Therefore the correct answer is a) Acetylcholine.
Answer:
it’s D. to reduce indigestion
Explanation:
Answer:
energy required is 0.247kJ
Explanation:
The formula to use is Energy = nRdT;
Where n is number of mole
R is the molar gas constant
dT is the change in temperature
n = reacting mass of mercury / molar mass of mercury = 27.4/200.59 = 0.137
dT = final temperature - initial temperature = 376.20 - 158.30 = 217.90K
R = 8.314Jper mol per Kelvin
Energy = 0.137 x 8.314 x 217.90 = 247.12J
Energy in kJ= 247.12/1000= 0.247kJ
El ácido sulfúrico es un ácido fuerte y por eso disocia completamente. La concentración de H+ será igual a la concentración de ácido sulfúrico (0.000475 M).
Para encontrar el pH, calcula -log[H+] = -log(0.000475) = 3.323
Para encontrar el pOH, sabes que pH + pOH = 14, y por eso pOH = 14 - pH = 14 - 3.323 = 10.677.
