Answer:
The correct answer is b the magnitude of the concentration gradient of the molecule.
Explanation:
Dffusion is one of most important membrane transport process that allow several molecules such as gases oxygen and carbon dioxide to pass directly across the plasma membrane.The is no involvement of carrier proteins or ion channels during passive diffusion.
During passive diffusion molecules are transported along their concentration gradient that means from the region of high concentration to region of low concentration,until the concentration of both regions become same.
Ag+CuSO4
Silver is lower than copper in the electrochemical series and therefore would not displace it in any reaction.
Answer:
I believe the answer is Xenon since it is a noble gas
Answer:
1. KNO3(s) ------> K^+(aq) + NO3^-(aq)
2. The dissolution is endothermic
3. The sign of the enthalpy of dissolution is positive
Explanation:
The sign of the enthalpy of dissolution depends on the hydration energy and the lattice energy.
For KNO3, the hydration energy is less than the lattice energy hence the dissolution is endothermic and the enthalpy of dissolution is positive.
Answer:
<em><u>True</u></em>
Explanation:
<em><u>Most rivers begins life as a tiny stream running down a mountain slope..... small streams meet and join together, growing larger and larger until the flow can be called river. On its way down, the water shapes the landscape by wearing away rocks and carving out a network of valley.</u></em>
