Your lungs infuse the blood with oxygen and get rid of the carbon diox
<span>the digestive system extracts glucose from the food you eat and deposits it in the blood </span>
<span>the circulatory system moves the oxygen, glucose, and carbon diox through our bodies enabling the cells to get the materials they need and remove the ones they dont</span>
I can't answer this question without knowing what the specific heat capacity of the calorimeter is. Luckily, I found a similar problem from another website which is shown in the attached picture.
Q = nCpΔT
Q = (1.14 g)(1 mol/114 g)(6.97 kJ/kmol·°C)(10°C)(1000 mol/1 kmol)
<em>Q = +6970 kJ</em>
The structure of proteins is ultimately determined by the sequence of nucleic acids.
Answer:
pH = 9.29
Explanation:
- C5H5N + H2O ↔ C5H5NH+ + OH-
∴ pKb = 8.75 = - Log Kb
⇒ Kb = 1.7783 E-9 = [OH-][C5H5NH+]/[C5H5N]
mass balance:
⇒ <em>C</em> C5H5N = 0.215 M = [ C5H5N ] + [C5H5NH+]
charge balance:
⇒ [OH-] = [C5H5NH+]
⇒ Kb = 1.7783 E-9 = [OH-]² / ( 0.215 - [OH-] )
⇒ [ OH-]² + 1.7783 E-9[OH-] - 3.8233 E-10 = 0
⇒ [OH-] = 1.9552 E-5 M
⇒ pOH = 4.708
∴ 14 = pH + pOH
⇒ pH = 9.29
Answer:
C. hydrogen bonding
Explanation:
Ammonia and hydrogen fluoride are both able to exhibit hydrogen bonding due to containing nitrogen (in ammonia) and fluoride (obviously in hydrogen fluoride). Remember the unique qualities of NOF. :)
