PV = nRT
⇒P1/T1 = P2/T2
⇒500/300 = 100/T2
⇒ T2 = 100×300/500 = 60K
Answer is D
Answer: condenstation.
Justification:
The polymerization by condensation is a well know chemical reaction in which two monomers ("small" molecules), each with (at least) two functional groups, combine and relase water as by-product. Actually, even if the by-product released is not water, yet the reaction is called condenstation, since the mechanism is basically the same.
An example of such reaction is the manufacturing of nylon 6,6, which is produced from adipic acid and 1,6-diamine hexane:
HOOC - [CH₂]₄ - COOH + nH₂N - [CH₂]₆ - NH₂ → - nylon - + nH₂O
I omitted the formula of nylon because it is large, and that is not the core of the question but the fact the kind of reaction: two molecules combine to form is a larger molecule, and water is released
It depends of the temperature and the pressure. If temperature and pressure are standard 1 mol forms 22.4 liter. So 33.6 liters form 33.6/22.4 = 1.5 mols.
Now calculate the molar mass of carbon dioxide: 12 g/mol + 2x16 g/mol = 44 g/mol
The mass of the 1.5 mols is 1.5mol * 44 g/mol = 66 g.
It is easier to predict the boiling point of heptene rather than its melting point because of their geometrical isomerism.
<h3>What is melting point?</h3>
Melting point is that point at which any compound changes its state from solid to another state liquid, and at this point both the states are present in equilibrium.
It is easier to predict the boiling point of heptene as in this molecule constant number of double bond is present its not changing. But due to double bond heptance shows cis and trans isomer, and among them one isomer will be stable and another one is unstable.
That's why it is not easy to predict the melting point.
Hence, due to geometrical isomers it is not easy to predict melting point.

In order to find out how many protons a sodium atom has, you have to look at the periodic table. Sodium is Na on the periodic table and you look for the number on the top of the symbol and you can see that it has 11 protons. To find out how many neutrons, you have to subtract 11 from the mass number, which is 23. 23-11 = 12.
12 neutrons; 11 protons
