Answer:

From what I personally know, Acenaphthylene 75%. Empirical Formula (Hill Notation): C12H8. CAS Number: 208-96-8. Molecular Weight: 152.19. Beilstein: 774092. EC Number:

Explanation:

Acenaphthylene, a polycyclic aromatic hydrocarbon is an ortho- and peri-fused tricyclic hydrocarbon. The molecule resembles naphthalene with positions 1 and 8 connected by a -CH=CH- unit. It is a yellow solid. Unlike many polycyclic aromatic hydrocarbons, it has no fluorescence. Acenaphthylene/Formula is C12H8.

I'm not sure if this will help you but this is what I know so I hope it does :)

Could you have identified a physical property of a substance before you performed the activity? Explain.
sasho [114]

You could identify a physical property of a substance before you performed the activity because the characteristics of a material known as its physical qualities are those that may be investigated independently of the substance's chemical makeup.

This is further explained below.

<h3>What is physical property?</h3>

Generally, Any attribute that can be measured and has a value that can be used to describe the state of a physical system is considered to be a physical property.

In conclusion, The changes that take place in a system's physical attributes may be utilized to provide a description of the transitions that take place between its momentary states.

Which equation represents a change that results in an increase in disorder?(1 ) I2(s)=&gt;I2(g)
ankoles [38]

Answer : The correct option is, (1) I_2(s)\rightarrow I_2(g)

Explanation :

Entropy : It measures the disorderedness or randomness of the molecule.

That means higher the disorderedness, higher will be the entropy.

As we are going from solid state to liquid state, liquid state to gaseous state, the disorderedness increases due to the less inter-molecular interaction between the molecules.

And, as we are going from gaseous state to liquid state, liquid state to solid state, the disorderedness decreases due to the more inter-molecular interaction between the molecules.

(1) I_2(s)\rightarrow I_2(g)

In this reaction, the disorderedness increases because the state changes from solid to liquid.

(2) CO_2(g)\rightarrow CO_2(s)

In this reaction, the disorderedness decreases because the state changes from gaseous to solid.

(3) 2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

In this reaction, the disorderedness decreases because the state changes from gaseous to solid.

(4) 2H_2(g)+O_2(g)\rightarrow 2H_2O(l)

In this reaction, the disorderedness decreases because the state changes from gaseous to liquid.

Hence, the correct option is, (1) I_2(s)\rightarrow I_2(g)
