A gas initially at 273k is heated such that it volume and pressure became twice their original volume what is the new temperatur
lord [1]

Answer:

<u>1092K</u>

Explanation:

We can use the combined gas law to answer this question:

P1V1/T1 = P2V2/T2,

where P, V and T are the Pressure, Volume, and Temperature for initial (1) and Final (2) conditions.  Temperatures must be in Kelvin.

The problem states that V2 = 2V1 and P2 = 2P1.

Let's rearrange to solve for T2, which is the question:

      T2 = T1(P2/P1)(V2/V1)

Note how the pressure and temperature values are written:  as ratios.  Enter the values:

       T2 = (273K)(P2/P1)(V2/V1)

        T2 = (273K)(2P1/P1)(2V1/V1)  [Use the expressions for V2 and P2 from above]

        T2 = (273K)(2)(2)

                       T2 = 1092K

Pls help! 2CO + O2 → 2CO2
jok3333 [9.3K]

The bond energy of each carbon-oxygen bond in carbon dioxide is d. 736 kJ

Since the chemical reaction is 2CO + O₂ → 2CO₂ and the total bond energy of the products carbon dioxide CO₂ is 1,472 kJ.

Since from the chemical reaction, we have 2 moles of CO₂ which gives 1,472 kJ and there are two carbon-oxygen, C-O bonds in CO₂, then

2 × C-O bond = 1,472 kJ

1 C-O bond = 1.472 kJ/2

C-O bond = 736 kJ

So, the bond energy of each carbon-oxygen bond in carbon dioxide is d. 736 kJ

What are the representative elements? Where are they located
WINSTONCH [101]
The representative elements are elements where the s and p orbitals are filling. The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling, and the inner transition metals are the elements where the f orbitals are filling.
