I think the answer must be B, although A is technically somewhat true too. Though the liver can regulate acid secretion, thus helping to balance the pH of blood by increasing or decreasing the acid secretion (can rid the body of excess acid through urine), the question doesn't specify that it balances the pH levels of BLOOD, and equally, multiple factors in the body have a role in balancing bodily pH levels, thus it is not the primary function of the liver. Thus, it must be B. The cells in the liver release an enzyme called renin, which activates angiotensin, which in turn activates the hormone aldostrene, which controls salt retention and elimination of potassium in the kidneys, thus affecting blood pressure and fluid balance.

Answer:
55641.656 × 10^23 molecules
Explanation:
Get the molar mass, multiply by amount of stuff, multiply by Avogadros number.
More detail in picture attached.
Hope it helps. Brainliest Appreciated. :)
Answer:
Explanation:
= Half-life of carbon = 5700 years
t = Time at which the remaining mass is to be found = 10400 years
= Initial mass of carbon = 11 g
Decay constant is given by
Amount of mass remaining is given by
The amount of the substance that remains after 10400 years is .
Answer:
Explanation:
the chemical equilibrium constant can be easily calculated since the concentrations at equilibrium are given.the calculation shows the value of Kc for the reversible reaction and forward reaction
It is a constant-volume type calorimeter that measures the heat of a particular reaction or measures the calorific value of the fuels. Bomb calorimeters are built in such a way that they can withstand the large pressure produced within the calorimeter due to the reaction or burning of fuel.
