First, how many valence electrons does hydroxide ion have? If it has something like 6 it would need 2 to get the max total of 8. Or perhaps it's 7. Then only one is needed. But if the number is 8 then 0 is required
D.) as you can tell the temperature is the x axis while pressure (atm) is the y axis, so therefore you’d find (0,0.25) which gives u solid because its not near water or gas
Answer:
15.5 km
Explanation:
1.55 x 10^4 m means 1.55 x 10000 = 15,500 m
1 km = 1000 meters
To convert to km we divide by 1000
So 15,500/1000
= 15.5 km
Given what we know, we can confirm that in a voltaic cell, the anode loses electrons and is oxidized, meanwhile, the cathode is reduced by gaining electrons.
<h3 /><h3>What is a voltaic cell?</h3>
- It is described as an electrochemical cell.
- These cells use chemical reactions to produce electrical energy.
- During this reaction, an anode loses electrons, thus oxidizing.
- Meanwhile, the cathode gains electrons and is reduced.
Therefore, given the nature of the voltaic cell, we can confirm that during its reaction, the anode is oxidized by losing electrons while the cathode becomes reduced by gaining them.
