Answer:
Is a substance that can maintain certain range of pH
Explanation:
A buffer is mixture of two salts that are complementary, one salt is acid and another is basic, but since then share some part of their structure, if you add to this mixture another acid, the basic salt can absorb it and still maintaining the same pH. If you pour a base, the acid salt will absorb it and again the final pH will remain the same. So the buffers are used to maintain the same pH does not matter if you add small quantities of an acid or base.
When we are performing IR spectroscopy for Cyclohexane and cyclohexene, we can distinguish them as cyclohexene has C-H carbon-hydrogen stretching so, it shows the absorption at 3000-2850 cm⁻¹ range, where the cyclohexane do not have this and it shows the -C=C- stretch at 1640-1680 cm⁻¹ range in the spectrum. So that is how we can distinguish both.
<h3>Answer:</h3>
0.0011 mol
<h3>Solution:</h3>
Data Given:
Mass of Mn = 62.0 mg = 0.062 g
Atomic Mass of Mn = 54.94 g.mol⁻¹
Calculate Moles of Mn as,
Moles = Mass ÷ M.Mass
Putting values,
Moles = 0.062 g ÷ 54.94 g.mol⁻¹
Moles = 0.0011 mol
