Answer:
Concept: Chemical Analysis
- Start by taking inventory of the elements that you have
- Make a list, one for the right side and another for the left side
- Then add coefficients to the elements to the right or left side to balance out the equation
Explanation:
We calculate the amount of carbon fixed as follows.

=
kg
= -1273.1 kJ/mol
= -393.5 kJ/mol
= -285.8 kJ/mol
Hence, total
reaction will be as follows.

= 
= 2802.7 kJ/mol
Therefore, calculate the number of moles of fixed carbon as follows.

= 
= 
Thus, we can conclude that the annual enthalpy change resulting from the photosynthetic carbon fixation over the land surface is
.
Molarity = moles of solute/volume of solution in liters.
There are 2.66 moles of KOH, the solute, and the volume of the solution is 0.750 L.
The molarity of this solution would thus be (2.66 moles KOH)/(0.750 L) = 3.55 M KOH.
Answer:
Correct answer is (D). as a weak acid it can cross the membrane when in its uncharged form.
Explanation:
Aspirin (acetylsalicylic acid, ASA) is an analgesic and anti-inflammatory agent use in the treatment of gentle to moderate pain, inflammation and fever. It is absorb in the stomach and intestine in an unchanged form.
