Answer:
pH = 2.56
Explanation:
The Henderson-Hasselbalch equation relates the pH to the Ka and ratio of the conjugate acid-base pair as follows:
pH = pKa + log([A⁻]/[HA]) = -log(Ka) + log([A⁻]/[HA])
Substituting in the value gives:
pH = -log(1.77 x 10⁻⁴) + log((0.0065M) / (0.10M))
pH = 2.56
Answer:
Your answer is ATOM
Explanation:
Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements.
Basically, they are the building block of life because everything made of matter has atoms
C. Saturated
When something is Saturated, it means that it is unable to absorb or dissolve any more of a solute at the given temperature and pressure.
Answer:
5 neutrons
Explanation:
There five isotopes of lithium. The most stable and abundant is lithium-7.
Its percentage is 92.5%. It has four neutrons. All lithium isotopes have same atomic number but different atomic mass because of different number of neutrons.
Lithium-8 have five neutrons.
Lithium-9 have six neutrons.
Lithium-11 have eight neutrons.
Lithium-4 has one neutron.
Lithium is alkali metal.
It is present in 1st group.
Its atomic number is 3.
Its atomic mass is 7 amu.
Lithium salts are used in psychiatric medicine.
