The offspring will have white hair is the correct answer, as white hair is the recessive gene.
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: It is charged because Protons are Positively charged, and it has 1 proton.
Answer:
Vapour pressure of a liquid varies with temperature
Explanation:
The vapour pressure of any liquid is directly proportional to the temperature of the liquid. This implies that, as the temperature of the liquid increases, the vapour pressure increases likewise and vice versa.
Since the vapour pressure of liquid varies with the temperature of the liquid, it is essential to know the water temperature in the experiment to determine the vapour pressure of water.
Answer:
The molar concentration of normal saline is 0.15 mol/L.
Explanation:
The mass of NaCl in 0.85% of normal saline is:
The molar concentration can be found using the following equation:
So we need to find the number of moles of NaCl in 1 liter of solution.
Where:
M: is the molar mass of NaCl = 58.44 g/mol
Hence, the molar concentration is:
Therefore, the molar concentration of normal saline is 0.15 mole per liter.
I hope it helps you!
