Calcular la fraccion molar de NaClO en una solucion blanqueadora comercial que comtiene 3,62% en masa de NaClO en agua
muminat

<em>Calculate the molar fraction of NaClO in a commercial bleach solution that contains 3.62% by mass of NaClO in water</em>

<em />

<h3>Further explanation</h3>

convert mass to mol

mol NaClO (MW=74.5 g/mol) :

\tt \dfrac{3.62}{74.5}=0.0486

mol H₂O (MW= 18 g/mol) :

\tt \dfrac{96.38}{18}=5.354

Total mol :

0.0486 + 5.354 = 5.4026

mol fraction of NaClO :

\tt X_{NaClO}=\dfrac{0.0486}{5.4026}=0.009=9.10^{-3}

The specific heat of gold is 0.126 J/gºC. How much energy is released
Schach [20]

Explanation:

Specific heat capacity of gold (S)

= 0.126 J /kg°C

mass (m) = 350 g = 0.35 kg

difference in temperature (dt)

= 88.5°C - 24.6°C

= 63.9° C

Now

Energy released (Q)

= m*s*dt

= 0.35 * 0.126 * 63.9

= 2.81799 Joule

Hope it will help :)

20. What happens to the wavelength of a wave if the frequency is increased?
nata0808 [166]

A wavelength's frequency and energy (E) drop as it becomes longer. You may conclude from these equations that the wavelength grows shorter as the frequency rises. The wavelength lengthens as the frequency drops.

Since frequency and wavelength are inversely related to one another, the wavelength of the wave falls as frequency increases.
