Answer:
Green
Explanation:
Positive: A strong green color in the flame indicates the presence of halogens (chloride, bromide, iodide but not fluoride).
Protein would be the main one.
Cellular respiration releases stored energy and glucose molecules and converts it into a form of energy that can be used by cells
Answer:
pH = 11.05
Explanation:
It is possible to answer this question using Henderson-Hasselbalch formula:
pH = pka + log₁₀ [A] / [HA⁺]
Where A in this case is weak base (dimethylamine) and conjugate acid (HA⁺) is dimethylamine hydrochloride.
As Ka= Kw / Kb = 1x10⁻¹⁴ / 7.4x10⁻⁴ = 1.35x10⁻¹¹ And pKa is -log Ka = <em>10.87 </em> pH of the solution is:
pH = 10.87 + log₁₀ [0.600] / [0.400]
<em>pH = 11.05</em>
<em></em>
