Answer:
E°= E°cathode- E° anode= 0.271-0.330= -0.59V
Explanation:
NB: the stoichiometry does not affect E°values,
And the more positive the E° values , the greater it's tendency to become spontaneous and hence irreversible, and the more negative the E° values the more likely to become less spontaneous and reversible, hence the above reaction is reversible
Answer:
90% of people marry there 7th grade love. since u have read this, u will be told good news tonight. if u don't pass this on nine comments your worst week starts now this isn't fake. apparently if u copy and paste this on ten comments in the next ten minutes you will have the best day of your life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say i love you
Explanation:
<u>Answer:</u>
<em>Substances known as </em><u>electrolytes</u><em> are found in blood which includes sodium and potassium.</em>
<u>Explanation:</u>
<em>Electrolytes are electrically charged particles</em> and they help in moving nutrients into the cell and removing waste particles out of the cell. Other <em>functions of electrolytes</em> include maintaining the salt level as well as <em>pH level of the body. </em>
The electrolyte potassium is present in <em>small quantities in the fluid part of blood, namely plasma.
</em>
Regulating body muscle contraction is the main function of potassium. The fluid region outside cells contains a <em>major portion of sodium which maintains the water balance of the body.
</em>
The standard temperature is 0c.
the standard pressure is 1atm.

So,
The octet rule really only holds up for the second period elements, and only certain elements in that period, for that matter. Elements in the third periods and beyond can have expanded octets.
Draw Lewis dot diagrams for each molecule.
:
P is the central atom bonded individually to each Cl. The only logical diagram is that with three lone pairs surrounding each Cl and the P single-bonded to each Cl atom. If you count the bonds, you will find that P has five pairs, or 10 electrons. This exceeds the octet rule.
:
The Lewis dot diagram for this molecule is a linear molecule with the Be in the center, singly bonded to both F's, each of which have three lone pairs. This means Be has only two pairs, or four electrons. While not an example of a central atom that exceeds the octet rule, Be is one of the special elements that can stably have an incomplete octet.
:
The most stable diagram for this molecule is with S in the center with two lone pairs and singly bonded to each H atom. With four pairs, or 8 electrons, this molecule obeys the octet rule.
:
The diagram for this molecule is C in the center doubly bonded to each O atom. Each O atom has 2 lone pairs. C has four pairs, or 8 electrons. This molecule also obeys the octet rule.
Hope this helps!
