Vedmedyk [2.9K]
Blue litmus paper turning red means that the solution where the litmus paper was submerged is an acidic solution with a pH of less than 7. Another verification of the nature of the solution is the turning to red of methyl orange in acidic solutions. The answer then is D.

Elemental iodine (I 2) is a solid at room temperature. What is the major attractive force that exists among different I 2 molecu
Ulleksa [173]

Explanation:

As I_{2} is a covalent compound because it is made up by the combination of two non-metal atoms. Atomic number of an iodine atom is 53 and it contains 7 valence electrons as it belongs to group 17 of the periodic table.

Therefore, sharing of electrons will take place when two iodine atoms chemically combine with each other leading to the formation of a covalent bonding.

Hence, weak forces like london dispersion forces will be present between a molecule of I_{2}.

The weak intermolecular forces which can arise either between nucleus and electrons or between electron-electron are known as dispersion forces. These forces are also known as London dispersion forces and these are temporary in nature.

thus, we can conclude that london dispersion force is the major attractive force that exists among different I_{2} molecules in the solid.

Cortisol (molecular weight 362.47 g/mole), one of the major steroid hormones, is a key factor in the synthesis of protein. Its p
frez [133]

The molecular formula of cortisol is C₂₁H₃₀O₅

Explanation:

To find the cortisol formula we use the following algorithm:

divide each element percentage by the atomic weight of the element

for carbon 69.9 / 12 = 5.83

for hydrogen 8.34 / 1 = 8.34

for oxygen 22.2 / 16 = 1.41

now the we divide the obtained numbers by the lowest one, which is 1.41

for carbon 5.83/ 1.41 ≈ 4

for hydrogen 8.34 / 1.41 ≈ 6

for oxygen 1.41 / 1.41 = 1

the empirical formula of cortisol is C₄H₆O

the molecular formula of cortisol is (C₄H₆O)ₓ

70x = 362.47

x = 362.47 / 70

x ≈ 5.2

carbon ≈ 5.2 × 4 ≈ 21

hydrogen = 5 × 6 = 30

oxygen = 5 × 1 = 5

The molecular formula of cortisol is C₂₁H₃₀O₅
