Answer:
None of the given options show polymer made up of H₂C=CH-CN (Acrylonitrile).

Explanation:
Acrylonitrile (H₂C=CH-CN) which is a monomer on self linkage results in a large chain polymer called as Polyacrylonitrile.
The structure of Polyacrylonitrile is as follow,

--(H₂C-CHCN-)n--

Where n shows the number of Acrylonitrile units joined together in the formation of Polyacrylonitrile. This polymerization reaction can take place by different mechanisms including free radical mechanism, acid catalyzed addition or base catalyzed addition reaction.

The polymerization is shown below,

Which of the following is a definition of an acid? O a. releases heat when dissolved in water. O b. turns cloudy when dissolved

adell [148]

Answer: Option (d) is the correct answer.

Explanation:

According to Bronsted-Lowry an acid is defined as the specie which is able to donate hydrogen ions when dissolved in water.

For example, $HCl \rightarrow H^{+} + Cl^{-}$

On the other hand, bases are the species which are able to donate hydroxide ions when dissolved in water.

For example, $NaOH \rightarrow Na^{+} + OH^{-}$

Thus, we can conclude that a definition of an acid is that it donates H ions when dissolved in water.

when 1.570 grams of the compound is vaporizedar 300 degrees celius and 1 atmosphere, the gas occupies a volume of 577 milliliter

Archy [21]

Answer:

128 g/mol

Explanation:

The molar mass is how much a mol of the substance weight.

In this question the weight is given (1.570 g).

To find the number of moles in the sample, we use the ideal gas law: PV=RnT

P= 1atm

V= 577mL= 0.577L

R (universal gas constant)= 0.08206( $\frac{atm*L}{mol*K}$ )

n= number of moles

T= 300°C= 573.15K

Solving for n:

n= $\frac{1 atm*0.577L}{0.08206\frac{atm*L}{mol*K}*573.15}$ <em>k</em>

n=0.0123mol

Molar mass= $\frac{1.570g}{0.0123 mol}$

Molar mass=128 $\frac{g}{mol}$

As an electron in an atom moves from the ground state to the excited state, the electron (1) gains energy as it moves to a highe

yawa3891 [41]

Electron requires energy to move from ground state to excited state(higher energy levels). Hence option 1 is correct. Hope this helps!
