The atmosphere is a mixture of gasses.
<u>Answer:</u> The standard EMF of the cell is 1.11 V
<u>Explanation:</u>
For the given chemical equation:

The half reaction follows:
<u>Oxidation half reaction:</u>
( × 3)
<u>Reduction half reaction:</u> 
To calculate the
of the reaction, we use the equation:

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
Calculating the
using above equation, we get:

Hence, the standard EMF of the cell is 1.11 V
Wind abrades rock by sandblasting, this is the process in which wind causes the
Answer:
2) HClO3 is stronger because chlorine is more electronegative than iodine.
Explanation:
The more electronegative the element is the more strong or acidic it becomes.
Chlorine being more electronegative than Iodine makes it easier for it to pull the electron of hydrogen more strongly and hence has a higher tendency to release a H+ unit. Hence that makes it stronger.
