Explanation:
Answer: The original volume in liters was 0.0707L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 0.85 atm
= final pressure of gas = 456 mm Hg = 0.60 atm (760mmHg=1atm)
= initial volume of gas = ?
= final volume of gas = 94.0 ml
= initial temperature of gas = 
= final temperature of gas =

Now put all the given values in the above equation, we get:

(1L=1000ml)
Thus the original volume in liters was 0.0707L
Answer:
Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. ... Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium.
Answer : The ions present in the solution of
are
and
in aqueous state.
Explanation :
When
is in aqueous solution then they dissociates into their ions.
The reaction in aqueous medium is,

The charge on potassium ion is +1 and on carbonate ion is -2. To neutralize the charge on carbonate ion, two potassium ion must be used.
Therefore, the ions present in solution of
are
and [tex]CO^{2-}_3[tex] in aqueous state.
