Explanation:
In the stomach, during digestion there are two types of:
-Mechanics: the degradation of food occurs, distension of the stomach walls is performed when they arrive, producing the Chyme.
Chemistry: through the participation of enzymes (pepsin activated by hydrochloric acid, which digests proteins in shorter amino acid chains and; gastric lipase that breaks fat giving glycerin products and fatty acids)
Answer:
pH= 12.7
Explanation:
a)Keep an emergency kit and fresh water in your car in the event of _an unexpected event.
b) pOH= -log[OH-]
pOH= -log[5.00×10^-2]
pOH= 1.3
But pH+pOH= 14
pH= 14-pOH= 14-1.3
pH= 12.7
The reaction corresponds to the combustion of propane (C3H8). The balanced reaction is:
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
The reaction enthalpy is given as:
ΔHrxn = ∑nΔH°f(products) - ∑ nΔH°f(reactants)
= [3ΔH°f(CO2(g)) + 4ΔH°f(H2O(g)] - [1ΔH°f(C3H8(g)) + 5ΔH°f(O2(g)]
= [3(-393.5) + 4(-241.8)] - [-103.9 + 5(0)] = -2043.8 kJ
The enthalpy for the combustion of propane is -2044 kJ
Answer:
9 is the answer
