Answer:
The half reaction occurring at this electrode will be given as:
Explanation:
In electrochemical cell reduction occurs at anode.
But the gold wire is connected to the positive terminal of the battery which means that gold wire will act as a cathode nad reduction will take place
The half reaction occurring at this electrode will be given as:
Answer:
I think the answer is 6.022*10^23
<span>Kr has 8 valence electrons plus 1 for each Kr-F single bond. Total = 10 elcetrons

I think E sorry if I’m wrong
Answer:
B?
Explanation:
In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles. Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
