How is electronegativity related to covalent bonding?

Chemistry
1 answer:
Vinvika [58]3 years ago
4 0
Covalent bonds form when atoms share electrons. This sharing allows each atom to achieve its octet of electrons and greater stability. Methane, CH 4<span>, the simplest organic compound, contains covalent bonds. Carbon has four valence electrons, while hydrogen has one valence electron. By sharing these outer‐shell electrons, carbon and hydrogen complete their valence shells and become more stable. The duet of electrons on the hydrogen is isoelectronic with helium and forms a complete shell.</span>

Why is an earth called natural green house. explain in brief​
crimeas [40]

Answer:

The greenhouse effect is a natural process that warms the Earth's surface. ... The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth's temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.

Need help calculating atomic mass (see pohoto for more info)
polet [3.4K]

Answer:

28.1

Explanation:

Divide the percentage abundances by 100:

92.2% ÷ 100 = 0.922

4.7% ÷ 100 = 0.047

3.1% ÷ 100 = 0.031

multiply them by their corresponding mass number:

0.922×28 = 25.816

0.047×29 = 1.363

0.031×30 = 0.93

add them all together to get your final answer:

25.816 + 1.363 + 0.93 = 28.109

to one decimal place:

28.1

I hope that helps!!!

The reaction between nitrogen dioxide and carbon monoxide is NO2(g)+CO(g)→NO(g)+CO2(g)NO2(g)+CO(g)→NO(g)+CO2(g) The rate constan
Alex17521 [72]

Answer : The rate constant at 525 K is, 0.0606M^{-1}s^{-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 701K = 2.57M^{-1}s^{-1}

K_2 = rate constant at 525K = ?

Ea = activation energy for the reaction = 1.5\times 10^2kJ/mol=1.5\times 10^5J/mol

R = gas constant = 8.314 J/mole.K

T_1 = initial temperature = 701 K

T_2 = final temperature = 525 K

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

\log (\frac{K_2}{2.57M^{-1}s^{-1}})=\frac{1.5\times 10^5J/mol}{2.303\times 8.314J/mole.K}[\frac{1}{701K}-\frac{1}{525K}]

K_2=0.0606M^{-1}s^{-1}

Therefore, the rate constant at 525 K is, 0.0606M^{-1}s^{-1}
