Answer: the concentration of C6H5 NH3+ = 0.031M
Explanation:
From question pH= 5.47
pH+pOH= 14
pOH= 14-5.47= 8.53
Using the Henderson Hasselbalch equation
pOH =pKb + log (salt/base)
8.53 = 9.13 + log(salt/0.125)
8.53-9.13= log(salt/0.125)
-0.6= log(salt/0.125)
Antilog (-0.6)=salt/0.125
0.251= salt/0.125
Salt conc.= 0.125×0.251=0.031M
Answer: 1.325x10^24 atoms S
Explanation:
2.2*avogadro number because S is monoatomic.
Compounds are pure substances made of different kinds of atoms chemically bonded together. Briefly discuss the difference between an element and a compound. An element is a pure substance and it's made on only kind of atom. A compound is a pure substance made of two or more elements that are combined chemically.
Answer: It depends on the concentration of all solutes in the solution (ie, its osmolarity). A solution with low osmolarity is hypotonic and vice versa. Solutions having the same osmolarity are isotonic. Water in pools and rivers is hypotonic compared with sea water, but water from the Dead Sea is hypertonic.We do not swell and pop when we go swimming in a hypotonic swimming pool because our skin protects us from the external environment and does not let water cross into or out of our body surfaces. ... hope this helps have a great day
