Juliette [100K]

Answer:

The  pressure is P_f  =  0.93 \  atm

Explanation:

From the question we are told that

   The  volume of  Ne  is  V_N  = 2.50 \ L

    The volume  of  CO is  V_C =  2.00 \  L

    The  pressure of  Ne is  P_N  =  1.09 \ atm

      The  pressure of  CO is P_C =  0.773 \  atm

The  number of  moles of  Ne present is evaluated using the ideal gas equation as

      n_N  =  \frac{P_N  *  V_N}{R T}

=>   n_N  =  \frac{1.09  *  2.50 }{R T} =  \frac{2.725}{RT}

The  number of  moles of  CO present is evaluated using the ideal gas equation as

      n_N  =  \frac{P_C  *  V_C}{R T}

=>   n_N  =  \frac{0.73  *  2.00 }{R T} =  \frac{1.46}{RT}

The  total number of moles of gas present is evaluated as

        n_T  =  n_N  +  n_C

        n_T  =  \frac{2.725}{RT}  +   \frac{1.46}{RT}

      n_T  =  \frac{4.185}{RT}

The  total volume of gas present when valve is opened is  mathematically represented as

                V_T  =  V_N  + V_C

    =>        V_T  =  2.50 + 2.00 =  4.50 \  L

So

  From the ideal gas equation the final pressure inside the system  is mathematically represented as

         P_f  =  \frac{n_T  *  RT }{ V_T}

=>      P_f  =  \frac{[\frac{4.185}{RT} ]  *  RT }{ 4.50}

=>       P_f  =  0.93 \  atm

Provide background information about different types of chemical reactions.
Zepler [3.9K]

Answer:

.

Explanation:

-Synthesis reactions are reactions that appear when two distinct atoms or molecules engage to structure a specific molecule or compound. Most of the time, when a synthesis response occurs, electricity is launched and the response is exothermic. However, an endothermic consequence is additionally possible.

-A decomposition response starts offevolved from a single substance and produces extra than one substance; that is, it decomposes. One substance as a reactant and greater than one substance as the merchandise is the key attribute of a decomposition reaction. For example, in the decomposition of sodium hydrogen carbonate (also recognized as sodium bicarbonate)

-A single-replacement response (sometimes referred to as a single-displacement reaction) is a chemical response in which one aspect is substituted for every other factor in a compound, producing a new aspect and a new compound as merchandise

-A double-replacement response (sometimes referred to as a double-displacement reaction) takes place when components of two ionic compounds are exchanged, making two new compounds. A attribute of a double-replacement equation is that there are two compounds as reactants and two distinctive compounds as product

-A combustion response happens when a reactant combines with oxygen, many instances from the atmosphere, to produce oxides of all different factors as products; any nitrogen in the reactant is transformed to elemental nitrogen, N2. Many reactants, referred to as fuels, incorporate normally carbon and hydrogen atoms, reacting with oxygen to produce CO2 and H2O
