This problem is about conversion and dimensional analysis. Important information to know:
1 atm = 760 torr = 101.325 kPa
For atm to torr conversion:
0.875 atm * (760 torr / 1 atm) = 665 torr
For atm to kPa conversion:
0.875 atm * (101.325 kPa / atm) = 88.7 kPa
Thus the answer is b) 665 torr and 88.7 kPa
Answer:
The answer to your question is 0.10 M
Explanation:
Data
Molarity = ?
mass of Sucrose = 125 g
volume = 3.5 l
Formula
Molarity = moles / volume
Process
1.- Calculate the molar mass of sucrose
C₁₂H₂₂O₁₁ = (12 x 12) + (1 x 22) + (16 x 11)
= 144 + 22 + 176
= 342 g
2.- Convert the mass of sucrose to moles
342 g of sucrose ------------------- 1 mol
125 g of sucrose -------------------- x
x = (125 x 1) / 342
x = 0.365 moles
3.- Calculate the molarity
Molarity = 0.365 / 3.5
4.- Result
Molarity = 0.10
Answer:
Gibbs Free Energy is given by the next equation: ΔG = ΔH - TΔS, where
ΔH - <u>change</u> in enthalpy
T - temperature in Kelvin
ΔS - <u>change</u> in entropy
ΔG can be:
- ΔG>0 positive(not spontaneous reaction)
- ΔG<0 negative(spontaneous reaction)
- ΔG=0(in equilibrium).
→ When the proteins are denatured, the entropy of the system increases. Therefore, the ΔS also increases and becomes more positive.
→ From the equation we see that positive value of ΔS contributes to negative value of ΔG.
The proteins are stable when there is no spontaneous reaction, thus, the ΔG>0 is required. Which means that ΔH has to be large and positive to counteract the influence of ΔS.
A habitat must include all of the following except C. More than one population of a given species.
