Cellular respiration is the process by which the chemicalenergy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
The change in energy level is equivalent to the energy of the released photon. This is related by Planck's equation:
E = hcf
The higher the energy change, the greater the frequency, f, of the photon.
Answer:
b) 18.5 g
Explanation:
The first step is the <u>calculation of number of moles</u> of with the molarity equation, so:
With the <u>volume in "L" units</u> (342.6 mL= 0.342 L ) we can <u>find the moles</u>, so:
Now, we have to calculate the <u>molar mass</u> to convert the moles to grams. For this we have to know the <u>atomic mass</u> of each atom:
Li ( 6.94 g/mol)
N (14 g/mol
O (16 g/mol)
With these values and the number of atoms in the molecule we can do the math:
(6.94 x 1) + ( 14 x 1) + (16 x 3 ) = 68.94 g/mol
The final step is the <u>calculation of the grams</u>, so:
<u>We will need 18.5 g of LiNO3 to do a 0.783 M solution with a volume 342.6 mL.</u>
Answer:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
For example:
Here, is loosing a proton, thus it is considered as a bronsted acid and after losing a proton, it forms which is a conjugate base.
And, is gaining a proton, thus it is considered as a bronsted base and after gaining a proton, it forms which is a conjugate acid.
The sequence of the acids and bases in the above equation are:
