I think is A) made of only one king of atom.
Answer:
A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.
Explanation:
Electrochemical cell -
Device used for the conversion of chemical energy to electrical energy is called electrochemical cell.
it is based on oxidation reduction reaction.
Electrolyte is a solvent in which ions are dissolved and two electrodes are dipped in it.
Anode electrode is responsible for oxidation, and the cathode electrode is responsible for reduction.
The electrochemical cell is composed of two electrodes dipped in an electrolyte , and which are further connect by salt bridge .
Salt bridge firstly connects the circuit and allows the movement of ions and , resists any mixing of the solution , and helps to maintain the electrical neutrality condition .
Hence , from the question , the correct option about salt bridge is the first option .
Answer:
458ml
Explanation:
According to charles law, ![$\frac{V_{1}}{T_{1}} =\frac{V_{2}}{T_{2}} $](https://tex.z-dn.net/?f=%24%5Cfrac%7BV_%7B1%7D%7D%7BT_%7B1%7D%7D%20%3D%5Cfrac%7BV_%7B2%7D%7D%7BT_%7B2%7D%7D%20%24)
Given values,
Volume occupied ![$V_{2}=500ml$](https://tex.z-dn.net/?f=%24V_%7B2%7D%3D500ml%24)
Temperature ![$T_{1}=25.0^{\circ}C=25+273=298K$](https://tex.z-dn.net/?f=%24T_%7B1%7D%3D25.0%5E%7B%5Ccirc%7DC%3D25%2B273%3D298K%24)
Second temperature ![$T_{2}=0.0^{\circ}C=273K$](https://tex.z-dn.net/?f=%24T_%7B2%7D%3D0.0%5E%7B%5Ccirc%7DC%3D273K%24)
Volume ![$V_{2}=?$](https://tex.z-dn.net/?f=%24V_%7B2%7D%3D%3F%24)
From charles law, ![$V_{2}=\frac{V_{1} \times T_{2}}{T_{1}}$ \\$=\frac{500 \times 273}{298}$\\$=458ml$](https://tex.z-dn.net/?f=%24V_%7B2%7D%3D%5Cfrac%7BV_%7B1%7D%20%5Ctimes%20T_%7B2%7D%7D%7BT_%7B1%7D%7D%24%20%5C%5C%24%3D%5Cfrac%7B500%20%5Ctimes%20273%7D%7B298%7D%24%5C%5C%24%3D458ml%24)
Volume occupied by the oxygen at 0.0°C is 458ml
Answer: Water inside the seed coat creating a pushing force, breaking the seed coat.
Explanation:
Seed germination can be defined as the process by which a new plant emerge out from a seed. The radicle is the first emerging part from a seed and it develops into a root and the plumule is the second emerging part and it develops into a shoot. The light, water, adequate temperature, and soil are the factors that are necessary for seed germination.
According to a given situation, the popcorn kernel will receive the moisture necessary for the germination process, the water will imbibe into the seed coat creating pressure inside the seed and which will cause the seed coat to break and the new plant parts or seedling will emerge out of the seed coat.
The conversion factor between yards to inches is 1 yard is equal to 36 inches. In converting 16.7 inches to yards, one must simply multiply it with the conversion factor.
16.7 inches *(1 yard/36 inches) = <span>
<span>0.463888889 yards
The answer is 0.46 yards.</span></span>
