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.
Answer:b
Explanation:
When a covalent bond is nonpolar, it implies that there is a symmetric distribution of the electron cloud between the the two nuclei. That is, the electron cloud of the shared pair is positioned equidistant from the two bonding atoms. In this case, the both atoms attract electrons equally and the molecule lacks a permanent dipole.
The wire could break when your on it. Another one this is kind of personal if you don't stop yourself on the zip line you could slam off the rope or post.
Letter C would be the correct answer
The electron is travelling with a velocity of 1.123 × 10⁷m/s if it has a wavelength of 8.20 km.
<h3>How to calculate velocity of an electron?</h3>
The velocity at which an electron travels can be calculated using the following formula:
λ = h/mv
Where;
- H = Planck's constant
- m = mass of electron
- v = velocity of electron
- λ = wavelength
- Planck's constant (h) = 6.626 × 10−³⁴ J⋅s.
- mass of electron (m) = 9.109 × 10−³¹ kg
- wavelength = 8200m
8200 = 6.626×10−³⁴ / 9.109 × 10−³¹V
8200 = 7.3 × 10-⁴V
V = 8200 ÷ 7.3 × 10-⁴
V = 1.123 × 10⁷m/s
Therefore, the electron is travelling with a velocity of 1.123 × 10⁷m/s if it has a wavelength of 8.20 km.
