Describe how hydrogen and oxygen form water.

Chemistry

bekas [8.4K]3 years ago

Hydrogen and Oxygen by themselves have 1 and 6 valence electrons, respectively. 8 valence electrons is stable, so the atoms form bonds with each other to achieve 8 valence e-.

1 H atom + 1 H atom + 1 O atom = 8 valence e-

The oxygen atom requires 2 electrons to complete its valance shell. Hydrogen is special in that it can eighter give or take one electron and still be stable. So hydrogen gives its electron  to oxygen, and two hydrogens fill up all of oxygen's  valance shell, and it forms water.

What are all of the elements that end with F electrons
jonny [76]

The elements whose electron configurations end with f electrons are in the Lanthanide and Actinide series: those long series at the bottom of the Periodic Table (see image).

The atoms are adding electrons into f orbitals, but the f electrons are not always the last electrons in the electron configuration.

For example, the electron configuration of Eu is [Xe]6s²4f⁷, but that of Gd

is [Xe] 6s²4f⁷5d.

I have blocked off in <em>red</em> all the <em>exceptions</em> like Gd.

scientific description about the pizza dough doubles its size when it is placed in a warm place . how does this happen
Marina CMI [18]
Answer is: because carbon(IV) oxide is released.
For example if baking soda is used for <span>the pizza dough, than on heat carbon(IV) oxide is product of chemical reaction:
2NaHCO</span>₃ → Na₂CO₃ + CO₂ + H₂O.
If we use yeast (<span>single-celled microorganism)</span>, also carbon(IV) oxide produced, because yeast turns sugars into carbon(IV) oxide.

The gas phase reaction 2 N2O5(g) → 4 NO2(g) + O2(g) has an activation energy of 103 kJ/mol, and the first order rate constant is
vaieri [72.5K]

Answer:  The rate constant at 296 K is 1.51\times 10^{-3}min^{-1}

Explanation:

According to the Arrhenius equation,

K=A\times e^{\frac{-Ea}{RT}}

or,

\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]

where,

K_1 = rate constant at 266 K = 1.35\times 10^{-5}min^{-1}

K_2 = rate constant at 296 K = ?

Ea = activation energy for the reaction = 103 kJ/mol = 103000 J/mol

R = gas constant = 8.314 J/mole.K

T_1 = initial temperature = 266 K

T_2 = final temperature = 296 K

Now put all the given values in this formula, we get

\log (\frac{K_2}{1.35\times 10^{-5}})=\frac{103000}{2.303\times 8.314J/mole.K}[\frac{1}{266}-\frac{1}{296}]

\log (\frac{K_2}{1.35\times 10^{-5}})=2.049

K_2=1.51\times 10^{-3}min^{-1}

Thus the rate constant at 296 K is 1.51\times 10^{-3}min^{-1}
