Answer:
<u>solution A: 14% salt solution solution B: 1% salt solution:</u> net flow towards solution A.
<u>solution A: 5% salt solution solution B</u>: 5% salt solution: no net flow
<u>solution A: 4% salt solution solution B</u>: 13% salt solution: net flow towards solution B.
Explanation:
<em>This is a simple case of osmosis - the movement of water molecules of the region of lower concentration of solute to the region of higher concentration of solute through a permeable membrane. </em>
The net movement of water will always be towards the solution with higher salt concentration. Hence;
- <u>solution A: 14% salt solution solution B: 1% salt solution:</u> net movement of water would be towards solution A.
- <u>solution A: 5% salt solution solution B</u>: 5% salt solution: no net movement
- <u>solution A: 4% salt solution solution B</u>: 13% salt solution: net movement of water would be towards solution B.
Answer:
The combustion of ethanol is an exothermic reaction. In addition to the formation of new compounds, the chemical reaction that takes place when ethanol is burnt also releases a lot of heat, 277.7 kJ per mole of ethanol. In summary, when ethanol burns, it reacts with oxygen to produce carbon dioxide, water and heat.
Explanation:
Solvency, cohesion, adhesion, hydrogen bonding, chemical reactivity, and thermal stability are all important properties of water.Water has the specific cappotential to dissolve many polar and ionic materials. This is vital to all residing matters because, as water travels thru the water cycle, it takes many precious vitamins along side it! Water has excessive warmness capacity.
Water's enormous functionality to dissolve a lot of molecules has earned it the designation of “regular solvent,” and it's far this cap-potential that makes water such a useful life-maintaining force. On a organic level, water's position as a solvent allows cells shipping and use materials like oxygen or vitamins.
A water molecule has 3 atoms: hydrogen (H) atoms and one oxygen (O) atom. That's why water is every so often known as H2O. A unmarried drop of water incorporates billions of water molecules.
