Answer:
True
Explanation:
Diffusion is the movement of the particles of a substances from a region of higher concentration to a region of lower concentration.
Diffusion occurs in response to a concentration gradient.
In this case, the dye is at a higher concentration at the middle of the shallow dish of water. Diffusion causes the dye to spread out gradually thereby causing the red cloud to grow larger with time.
Answer:
450 g/mol
Explanation:
To solve the problem the problem, it is necessary to use Graham's Law of effusion
This answer is consistent with what we know. A heavier gas will require more time to effuse than a lighter gas

Answer:
ΔErxn = -6212.6kJ/mol
Explanation:
When 0.538 g of biphenyl (C₁₂H₁₀) undergoes combustion in a bomb calorimeter, the temperature rises from 26.1 ⁰C to 29.8 ⁰C.
Matrix-derived protons are translocated across the mitochondrial membrane by altering pKa values of functional groups located on the inner and outer faces of the membrane.
<u>Explanation:</u>
The translocation of protons occurs across the inner mitochondrial membrane by two mechanisms. This dislocation occurs with the electron transport system protein complexes. The two mechanisms are described below.
First one is the redox loop mechanism. In this mechanism a redox reaction takes place. The separation of H+ and e- thereby resulting in the electron transport system protein. The opposite side of inner mitochondrial membrane is the place where it gets deposited.
Next one is the proton pump mechanism. Here the translocation of matrix-derived protons take place on the inner mitochondrial membrane . this takes place with the alteration of pKa values of functional groups that have the location the inner and outer faces of the membrane.
