Answer:
the answer is Fe2O3
Explanation:
The thermite reaction is described by the equation below: A welder has ... How much of this reactant should he order to make sure he runs out of both reactants at the same time? Round to the nearest hundredth and do not round any of your work until the very end. He should order Fe2O3 g of the limiting reactant.
Answer is: standard metal cations are sodium cation (Na⁺), potassium cation (K⁺), magnesium cation (Mg²⁺) and calcium cation (Ca²⁺).
Soap<span> is a </span>salt<span> of a </span>fatty acid. When soap have sodium and potassim cations, that is toilet soap and when soap have magnesium and calcium cations, that soap is called <span>metallic soap.</span>
Answer:

Explanation:
Hello,
At first, we compute liquid-phase molar fractions:

Now, by means of the fugacity concept, for hexane, for instance, we have:

In this manner, at 25 °C the vapor pressure of hexane and heptane are 0.198946 atm and 0.013912 atm repectively, thus, the total pressure is:

Finally, from the hexane's fugacity equation, we find its mole fraction in the vapour as:

Best regards.
1.194 mol
