You have 15.0 L of nitrogen gas at 100°C and 200 kPa. What volume of gas will you have at STP?
Pavel [41]
Actually, you do NOT need to calculate the number of moles, so you do NOT need to convert the volume and pressure. (You DO have to convert the temperature.) That's because for this problem, pV/T is constant, so the units cancel (but the temperature scale matters). 

<span>200kPa * 15L / 373K = 101kPa * V / 273K </span>
<span>V = 21.7 L </span>

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}

Using complete sentences, explain how to predict the products and balance the reaction between sulfuric acid and potassium hydro
My name is Ann [436]

Answer:

The answer to your question is given below.

Explanation:

The reaction of sulfuric acid and potassium hydroxide is called neutralisation.

Neutralisation is a reaction involving an acid and a base which produces salt and water only.

For the react between sulfuric acid, H2SO4 and potassium hydroxide, KOH, we can predict the products obtained as follow:

H2SO4 + KOH —>

In solution, H2SO4 and KOH will dissociate as follow:

H2SO4(aq) —> 2H^+(aq) + SO4^2-(aq)

KOH(aq) —> K^+(aq) + OH^-(aq)

H2SO4 + KOH —>

2H^+(aq) + SO4^2-(aq) + K^+(aq) + OH^-(aq) —> K^+(aq) + SO4^2-(aq) + 2H^+(aq) + OH^-

H2SO4 + KOH —> K2SO4 + H2O

Now, we can balance the above equation as follow:

H2SO4 + KOH —> K2SO4 + H2O

There are 2 atoms K on right side and 1 atom on the left side. It can be balance by writing 2 in front of ko as shown below:

H2SO4 + 2KOH —> K2SO4 + H2O

There are 2 atoms of H on the right side and a total of 4 atoms on the left side. It can be balance by writing 2 in front of H2O as shown below:

H2SO4 + 2KOH —> K2SO4 + 2H2O

Now,the equation is balanced.
