Unit conversion is a multi-step process, in which division or multiplication by a numeral factor is involved.
Density = 
(given)
Since, 
and
Now, converting to 
:
= 
.
Hence, density is .
Answer:
0.23 V.
Explanation:
<em>∵ ΔG° = -RT lnK.</em>
∴ ΔG° = -RTlnK = -(8.314 J/mol)(298 K) ln(7.3 × 10⁷) = - 44.86 x 10³ J/mol.
<em>∵ ΔG° = - nFE°</em>
∴ E° = - ΔG°/nF = - (- 44.86 x 10³ J/mol)/(2 x 96500 s.A/mol) = 0.2324 V ≅ 0.23 V.
Ionic bond I think. It is the only one related to ions.
Remember that in water, the concentration of hydronium ions, or H⁺, will equal the concentration of hydroxide ions. That is [H⁺] = [OH⁻].
Remember that Kw = [H⁺][OH⁻] for water and if [H⁺] and [OH⁻] are both equal, we can easily solve for them by taking the square root of Kw.
[H⁺] = sqrt(0.12*10^-14) = 3.46*10^-8
(2 sig figs. Keep some extra so there will not be a rounding error.)
and remember that pH = -log[H⁺] = -log(3.46*10^-8) = <span><span>7.46
</span>
</span>(The rules for sig figs are that if you take the log of a number with x significant figures, then the result should have x significant decimal places.)
The pH of water is <span>7.46</span>
Answer:
As balloons rise, air pressure around them diminishes. When the ballon is made of elastic material, it expands because of the excess pressure inside. Its volume increases and its internal pressure decreases
