Answer:
Step-by-step explanation:
The diagram of the right angle triangle is shown in the attached photo. To determine EF, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
12² = 8² + EF²
144 = 64 + EF²
EF² = 144 - 64 = 80
EF = √80 = 8.94
1) To determine Sin G, we would apply the Sine trigonometric ratio which is expressed as
Sin θ = opposite side/hypotenuse. Therefore,
Sin G = 8.94/12
CSC G = 1/Sin G = 12/8.94
2) taking F as the reference angle,
EG = opposite side
FG = hypotenuse
SinF = 8/12
3) Tan F = opposite side/adjacent side
Tan F = 8/8.94

Answer:
Step-by-step explanation:
From the given information:
ΔG° = -30.5 kJ/mol
By applying the following equation to calculate the value of K.
ΔG° =-RT㏑K
making ㏑ K the subject of the formula:
where;
Temperature at 25° C = (25 + 273)K
= 298K
R = 8.3145 J/mol.K (gas cosntant)
㏑K = 12.309
K = 221682.17
K = 2.22 × 10⁵
b) The reaction for the metabolism of glucose is given as:
From the above expression, let calculate the Gibbs free energy by using the formula:
At standard conditions;
The values of corresponding compounds are substituted into the equation above:
Thus,
Now, the no of ATP molecules generated =
= (-2875000 J/mol ) / -30500 J/mol
= 94.26
≅ 94 ATP molecules generated
