(3) HF. The strength of hydrogen bonding between molecules depends on the difference in the electronegativities of each atom in the molecule. Since fluorine is the most electronegative element, HF has the strongest hydrogen bonding.

Define and explain what an atom is
QveST [7]
Hi,

Atom is the second smallest form of any matter behind elementary particles. They are not visible to human eye. It consists of protons and neutrons in the atom core and electrons outside its core. All protons, neutrons and electrons are a part of atomic nuclei.

The more neutrons atom haves the bigger the mass of an atom is.

Number of electrons determines which element does atom represent. The more electrons atom haves the heavier element atom represents.

Different elements have different properties.

Hope this helped you understand what atom is better.

Hope this helps.

Hydrogen is prepared commercially by the reaction of methane and water vapor at elevated temperatures. CH₄(????) + H₂O(????) ⇌ 3
sammy [17]

Answer:

6.2846

Explanation:

Given that:-

Concentrations at equilibrium :-

[CH_4]=0.126\ M

[H_2O]= 0.242\ M

[CO]= 0.126\ M

[H_2]= 1.15\ M

The equilibrium reaction is:-

CH_4+H_2O\rightleftharpoons 3H_2+CO

The expression for equilibrium constant is:

K_{c}=\frac {\left [ H_2 \right ]^3\left [ CO \right ]}{\left [ CH_4 \right ]\left [ H_2O \right ]}

Applying the values as:-

K_c=\frac{1.15^3\times 0.126}{0.126\times 0.242}=6.2846

<u>The equilibrium constant for the reaction is:- 6.2846</u>
