<h2>Answer :</h2><h3><u>QUESTION ①)</u></h3>

✔ C5H4 has a molecular molar mass of :

M(C5H4) = 5 x 12 + 4 x 1
M(C5H4) = 60 + 4
M(C5H4) = 64 g/mol

✔ The molecular mass of C5H4 is therefore 64 g/mol.

But, 128/64 = 2

<h3>This is double the molar mass of C5H4, this molecule has the formula 2C5H4.</h3>

Arrange the molecules H2O, NH3, Ar, NaCl in order of expected increasing boiling points. 1. None of these 2. NaCl, H2O, NH3, Ar

Aleks04 [339]

Answer:

Option (4) is correct

Explanation:

NaCl is an ionic solid. $Na^{+}$ and $Cl^{-}$ ions are held together by strong coloumbic attractive force. Hence NaCl has highest boiling point'
Ar is a monoatomic molecule. Hence only weak london dispersion force exists between Ar atom/molecules. Hence it requires lowest amount of energy to boil and thereby possess lowest boiling point.
$NH_{3}$ and $H_{2}O$ are polar protic molecules. Hence they possess london dispersion force, dipole-dipole force and hydrogen bonding as intermolecular forces.
Dipole-dipole force is stronger in $H_{2}O$ than $NH_{3}$ due to more polar O-H bond than N-H bond. Also molecular weight of $H_{2}O$ is higher than $NH_{3}$ . So, more energy is required to boil $H_{2}O$ . So, $H_{2}O$ has higher boiling point than $NH_{3}$

Hence order of boiling point : $NaCl>H_{2}O>NH_{3}>Ar$

7. Which of the following pairs of atoms are isotopes? a) C14 & N14 b) U235 & U238 c) C12 & C12 d) C12 & N14 e)

Ede4ka [16]

Answer:

b) U235 & U238

Explanation:

Isotopes are the variants of a element which differ in the number of neutrons , and in the nucleon number consequently . All isotopes of the element have same number of the protons but different numbers of the neutrons.

(a) Isotopes are the properties of an element. Hence, not isotopes.

(b) Uranium is the element which exists in mass number 235 and 238 and they are the isotopes of the uranium element. Hence, they are isotopes.

(d) Isotopes are the properties of an element. Hence, not isotopes.
