Answer:
C. ways radiation is transferred into and through Earth's atmosphere
Explanation:
Answer:
ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
Explanation:
Answer:
See explanation and images attached
Explanation:
There are two compounds that could have molecular formula of C2H6O, they are ethanol and methoxy methane (trivial name: methyl ether). The structures of the two compounds are shown in the image attached as obtained from quora.
The boiling point of methoxymethane is -24.8°C while that of ethanol is about 78.5°C. The reason for the high boiling point of ethanol is the presence of intermolecular hydrogen bonding leading to a stronger intermolecular interaction compared to methoxymethane molecules held together only by very weak dispersion forces.
Answer:
Protonated form: 96.87%
Unprotonated form: 3.13%
Explanation:
To find the percentage of protoned and unprotoned forms of salicylic acid we must use Henderson-Hasselbalch equation:
pH = pKa + log [A⁻] / [HA]
<em>Where pKa of salicylic acid is 3.49; [A⁻] is the unprotonated form and [HA]:</em>
<em />
2.0 = 3.49 + log [A⁻] / [HA]
0.03236 = [A⁻] / [HA] <em>(1)</em>
And as:
[A⁻] + [HA] = 100% <em>(2)</em>
<em></em>
Replacing (2) in (1):
0.03236 = 100 - [HA] / [HA]
0.03236 [HA] = 100 - [HA]
1.03236[HA] = 100
<h3>[HA] = 96.87%</h3>
And [A⁻]:
[A⁻] = 100 - 96.87
<h3>[A⁻] = 3.13%</h3>

You need to check the weather to make sure its safe to hang glide, think about it you wouldn't want to go out and hang glide during a storm and if its not bad weather when you start, it could change depending on the forecast. So its good to always check and make sure there are no surprises when you are up in the sky.<span />
