Since neon has 8 valence electrons, a full octet makes neon stable. It is also a noble gas. Then, you do the configuration...
1s2 2s2 2p6
2s holds 2 valence electrons while 2p has 6 that equals a full octet.
76. The level of muddy water will decrease slightly if the model is left in a sunny location for several days because of Evaporation. The sun will vaporize the water found in the mud, turning it into it's gaseous state, which will then cause it to rise up and get stuck on the plastic wrap.
77. Precipitation
78.The reason that the sediment in the muddy water will remain the same is because the Mud will never evaporate like the water will, and therefore it will remain at the bottom of the container.
Hope that helps!
Answer:
That animal is a Carnivore.
Explanation:
The skull is that of a Panther which is a carnivore. Hope this helps
A Nitrogen got 7 electrons, which means every Nitrogen got 3 pairs of electrons and 1 single electron, ready to be shared.
A second nitrogen come with the same amount of electrons, 3 pairs and 1 single ready to shared.
The 2 nitrogens put in common their single electrons to create a pair.
Which means, that 1 pair of electron is shared between the nitrogens in a molecule of N2
Hope this Helps! :)
<span>The best choice is hypochlorous acid nitrous acid (HNO2) because it has the nearest value of pK to the desired pH.
pKa of </span>nitrous acid<span> is 3.34
If we know pKa and pH values, we can calculate the required ratio of conjugate base (NO2⁻) to acid (HNO2) from the following equation:
pH=pKa + log(conc. of base)/( conc. of acid)
</span><span>3.19=3.34 + log c(NO2⁻)/c(HNO2)
</span><span>3.19 - 3.34 = log c(NO2⁻)/c(HNO2)
-0.15 = log c(NO2⁻)/c(HNO2)
c(NO2⁻)/c(HNO2) = 10⁰¹⁵ = 1.41
