Answer: 62g

Explanation: You add 24g and 38 grams because when a substance reacts with another substance there is the same amount of grams in the product, so there would be 62 grams in the product because that is the amount of grams there is in the reactants.

Una masa de aire ocupa un volumen de5litro a una temperatura de 120c Cual será el nuevo volumen si la temperatura se reduce ala

zalisa [80]

Answer:

1. $V_2=2.5L$

2. $V_2=8000mL$

3. $V_2=176.3L$

Explanation:

¡Hola!

En este caso, dada la información para estos problemas, procedemos de la siguiente manera, basado en las leyes de los gases ideales:

1. Una masa de aire ocupa un volumen de 5 litros a una temperatura de 120 °C Cual será el nuevo volumen si la temperatura se reduce a la mitad:

Aqui, utilizamos la ley de Charles, asegurándonos que la temperatura está en Kelvin:

$\frac{T_2}{V_2} =\frac{T_1}{V_1} \\\\V_2 =\frac{V_1T_2}{T_1} \\\\V_2 =\frac{5L*196.5K}{393K} \\\\V_2=2.5L$

2. Un gas ideal ocupa un volumen de 4000 ml a una presión absoluta de 1500 kilo pascal Cual será la presión si el gas es comprimido lentamente hasta 750 kilo pascal a temperatura constante?

Aquí, utilizamos la ley de Boyle, dado que la temperatura se mantiene constante, calculando el volumen, ya que lo que se da es la presión final:

$\neq P_2V_2=P_1V_1\\\\V_2=\frac{P_1V_1}{P_2}\\\\ V_2=\frac{4000mL*1500kPa}{750kPa}\\\\V_2=8000mL$

3. Un gas ocupa un volumen de 200 litros a 95°C y 782 mmHg Cual será el volumen ocupado por dicho gas a 65°C y 815 mmHg:

Aquí, utilizamos la ley combinada de los gases ideales, asegurándonos que las temperaturas están en Kelvin:

$\frac{T_2}{P_2V_2} =\frac{T_1}{P_1V_1} \\\\V_2 =\frac{P_1V_1T_2}{P_2T_1} \\\\V_2 =\frac{782mmHg*200L*338K}{815mmHg*368K}\\\\V_2=176.3L$

¡Saludos!

While setting up a beaker to boil a solution on a hot plate, you notice that the stirring is erratic and unstable. What should y

Mama L [17]

Given what we know about lab safety, we can confirm that when dealing with unstable and erratic equipment such as the stirring mechanism, in this case, the best course of action is to deactivate the equipment until further notice.

<h3>Why should we turn off the equipment?</h3>

The erratic nature of the stirring mechanism is making the entire system unstable.
When dealing with a hot plate, and heating substances, we need to maintain stability at all times.
We do this to avoid spills that may cause burns or other unwanted damages.
Therefore, until we know why the stirring was erratic, we must turn the mechanism off.

Therefore, we can confirm that when dealing with faulty or unstable lab equipment, we must deactivate the equipment immediately in order to preserve our lab safety.
