First lets do Rb..we have 1 one the left and 3 on the right. so 3RbOH will balance that
PO4 is equal on both side
since we put 3 for RbOH now we have 3 O on the left
so we put 3 for H2O
now we have 6 H on each side so everything is balanced
<u>Answer:</u> The pressure of carbon dioxide needed is 2.94 atm
<u>Explanation:</u>
To calculate the partial pressure of carbon dioxide, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= molar solubility of carbon dioxide gas =
= pressure of carbon dioxide = ?
Putting values in above equation, we get:
Hence, the pressure of carbon dioxide needed is 2.94 atm
It is a chemical reaction of the metal surface with the oxygen that causes some of the metal to corrode and form the oxidation or better known as metal oxide on the surface.
