Answer : The work done on the gas mixture is -164 kJ

Explanation :

Formula used :

w=-p\Delta V\\\\w=-p(V_2-V_1)

where,

w = work done  = ?

p = pressure of the gas = 58.0 atm

V_1 = initial volume = 33.0 L

V_2 = final volume = 61.0 L

Now put all the given values in the above formula, we get:

w=-p(V_2-V_1)

w=-(58.0atm)\times (61.0-33.0)L

w=-1624L.atm=-1624\times 101.3J=-164511.2J=-164.5kJ\aprrox -164kJ

conversion used : (1 L.atm = 101.3 J)

Therefore, the work done on the gas mixture is -164 kJ

1 mole of no2(g) has a greater entropy than 1 mole of n2o4(g). true or false
bija089 [108]
In order to answer this, you need to find the empirical data for the standard entropies. Please refer to this link: http://www.mrbigler.com/misc/energy-of-formation.PDF

For NO₂ gas, the entropy is 240 J/mol-K. For N₂O₄ gas, the entropy is 304.2 J/mol-K. Therefore, <em>the statement is false.</em>

The kinetic molecular theory (KMT) deals specifically with
fgiga [73]
This kind of questions cannot be open because there might be many different answers depending of the focus.

In fact, I found the set of options that comes with this questions. This is:

A. behavior of ions.
B. molecular bonding.
C. molecular shape.
D. molecular motion.

Of course, the answer is the option D. molecular motion.

And, of course, you need an explanation.

It is good to know that the word kinetic refers to motion, so definetly kinetic molecular theory is a theory about the motion of the molecules.

With that you likely had been able to answer the question. But it is good to know what the molecular theory is.

The molecular kinetic molecular theory explains the properties and behavior of the gases in terms of the motion of its particles (molecules) making several assumptions about the energy, size and motion of such particles.

The characteristics of two different types of reactions are shown downwards
a_sh-v [17]

Answer:

Valence electrons are involved in Reaction B but not in Reaction A.

Explanation:

The description of reaction A in which protons are lost or gained by the atom of the element is a nuclear reaction. In nuclear reactions, the nucleons which are the protons and neutrons drives the reaction. No valence electrons in the orbiting shells are involved in this kind of reaction. During this type of reaction, an atom changes it identity to that of another.

Reaction B in which no identity change occurs is a chemical reaction. In chemical reactions bonds are formed by the atoms using the valence electrons that orbits round the central nucleus. The atoms remain the same but it chose to attain stability and an inert configuration by losing or gaining electrons.
