Hello!
The compound that forms from potassium and chromate is Potassium Chromate (K₂CrO₄)
This compound has a yellow lime color and is used in enamels, leather finishes, stainless steels and for the identification of silver ion in a silver nitrate solution. It is a powerful oxidizing agent and is produced by the treatment of potassium chromate with potassium hydroxide. It is a very toxic compound an is a known carcinogenic agent.
Have a good day!

Voltage<span>, </span>also called<span> electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
So ACTUALLY an "electromotive force", but of your answer choices.

4X + 3O₂ = 2X₂O₃
n(X₂O₃)=0.02225 mol
m(X)=4.000 g
x - the molar mass of metal
m(X)/4x=n(X₂O₃)/2
x=m(X)/{2n(X₂O₃)}
x=4.000/{2*0.02225)=89.89 g/mol
X=Y (yttrium)
Its running pressure in torr would be :
5.10 x 10^8 pa x 1kPa/1000 Pa x 760 / 101.325 kPa
= 5.10 x 10 ^5 x 76 x 10^-1 x 1.01325 x 10 ^-2
= 392.7375 x 10^2
= 3.927275 x 10^4
ope this helps
