Complete Question

The complete question is shown on the first uploaded image

Answer:

The pressure is  P  = 0.76 \ atm

Explanation:

From the question we are told that

   The mass of the carbon monoxide  is  m_c  =  17 \ g

   The temperature at which takes place  T  = 30 .0^oC =  30 + 273 =  303 K

   The volume of the sealed vessel  is  V  =  20 .0L

Generally the ideal gas law is mathematically represented as

        PV  =  nRT

Where R is the gas constant with value  R =  0.0821  \ L \ atm \ mol^{-1} K^{-1}

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

             n =  \frac{m_c}{M_c}

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

        M_c  =  28 \ g/mol

So     n  =  \frac{17}{28}

         n  =0.6071

Now Making P the subject we have

           P  =\frac{ 0.6071 * 0.0821 * 303}{20}

           P  = 0.76 \ atm

Why reactivity of elements in group 1 increase from lithium to francium?
labwork [276]

Answer:

As you go down group 1, the number of electron shells increases – lithium has two, sodium has three, and so forth. The attraction from the positive nucleus to the negative electron is less. This makes it easier to remove the electron and makes the atom more reactive.
