Answer:

All liquid glow products depend on a chemical process known as CHEMILUMINESCENCE to produce their light. Chemiluminesence is a chemical reaction that causes a release of energy in the form of light. To produce this light the electrons in the chemicals become excited and rise to a higher energy level.To utilise this process glowsticks contain two liquids; hydrogen peroxide and tert-butyl alcohol. When mixed together it is these liquids that create the glow. Fluorescent dyes are also used in the alcohol to alter the colour of the light emitted. Chemiluminesence is a chemical reaction that causes a release of energy in the form of light.

Un gas ocupa un volumen de 1475 ml a la presión de 1145 hPa .Se le permite expandir, trabajando isotérmicamente, hasta que su pr
Gnom [1K]

Answer:

2465.63 mL o 2.65 L

Explanation:

En este caso, como ya el ejercicio está diciendo que el gas se expande de forma isotérmica, significa que la temperatura en la cual se está trabajando es constante. Por ejemplo, si al principio estaba a 25 °C, entonces al final del proceso también estará a esa temperatura.

Como la temperatura es constante, la expresión para un gas ideal no puede ser utilizada. En su lugar, usamos la ley de Boyle que es para temperatura constante y es la siguiente:

P₁V₁ = P₂V₂

Entonces, solo debemos tomar en cuenta que las unidades respectivas de presión y volumen son las correctas y además, que sean las mismas.

En este caso P1 = 1145 hPa. Debemos convertir las unidades de Pascal a atmosfera. en este caso, la conversión es la siguiente:

1 atm -------> 1.01325x10⁵ Pa

Pero tenemos hPa, y 1 hPa son 100 Pa, entonces:

1145 hPa * 100 Pa / 1 hPa = 114500 Pa

Ahora aplicamos la conversión previa para tener la presión en Atm:

P₁ = 114500 Pa * 1 atm / 1.01325x10⁵ Pa = 1.13 atm

Ahora podemos calcular el volumen final del gas. Debería estar en Litros pero podemos trabajar en mililitros y luego convertirlo a Litros.

V₂ = P₁V₁ / P₂

V₂ = 1475 * 1.13 / 0.63

V₂ = 2645.63 mL o simplemente 2.65 L

Este sería el volumen final del gas.

You preform an experiment using 4.0 m hcl. And 2.4 m naoh. The experiment calls for 5.0 ml of hcl and 10.0 ml of naoh. How many
Gnom [1K]

Answer:

0,020 moles of NaCl

Explanation:

For the reaction:

NaOH + HCl → NaCl + H₂O

The moles of NaOH are:

10,0 mL ≡ 0,0100L × 2,4mol/L = 0,024 moles of NaOH.

In the same way, moles of HCl are:

5,0 mL ≡ 0,0050L × 4,0mol/L = 0,020 moles of HCl.

The limiting reactant is the reactant that is completely used in the reaction.

In this case, as moles of HCl are less than moles of NaOH, limiting reactant is HCl.

That means that moles of NaCl that are produced are the same moles of HCl, <em>0,020 moles</em>

<em></em>

I hope it helps!

Xco3 enter the group number of x
Mademuasel [1]

We know that C has a formal charge of +4 while each O element has a formal charge of -2, therefore the formal charge of X is:

X + 2 – 2 * 3 = 0

X + 2 – 6 = 0

X = 4

<span>So X has a group number of 4.</span>
