A reaction between liquid reactants takes place at in a sealed, evacuated vessel with a measured volume of . Measurements show that the reaction produced of carbon monoxide gas. Calculate the pressure of carbon monoxide gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Be sure your answer has the correct number of significant digits.

Complete Question

The complete question is shown on the first uploaded image

The pressure is  

Explanation:

From the question we are told that

   The mass of the carbon monoxide  is  

   The temperature at which takes place  

   The volume of the sealed vessel  is  

Generally the ideal gas law is mathematically represented as

Where R is the gas constant with value  

n is the number of moles of carbon monoxide  which is mathematically evaluated as

where is the molar mass of carbon monoxide which is a constant with value

So    

Now Making P the subject we have

answer; capital earns interest; entrepreneurship receives a profit or incurs a loss;

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
