Bingel [31]
Equation is:

Ca(NO3)2 + Na3PO4 —> NaNO3 + Ca3(PO4)2

Balance it out

3Ca(NO3)2 + 2Na3PO4 —> 6NaNO3 + Ca3(PO4)2

You have 96.1g of Calcium Nitrate

Moles = Mass/Molar Mass

Molar mass of Calcium Nitrate is 164.088 g/mol

96.1g / 164.088 g/mol =0.586 moles

Mole ratio is 3:1

Therefore 0.586/3 moles of calcium phosphate

Moles x molar mass = mass

0.586/3 x 310.18 g/mol = 60.6~g roughly as theoretical yield

El volumen de un gas en un recipiente cerrado es de 3.5 litros a una temperatura de 25oC y una atmósfera constante de presión. ¿
polet [3.4K]

Answer:

El volumen del gas en el recipiente es 3.29 L si se disminuye la temperatura a 7°C

Explanation:

La Ley de Charles es una ley de los gases que relaciona el volumen y la temperatura de una cierta cantidad de gas a presión constante.

Esta ley establece que el volumen es directamente proporcional a la temperatura del gas. Es decir que si la temperatura aumenta, el volumen del gas aumenta, mientras que si la temperatura del gas disminuye, el volumen disminuye.

Matemáticamente, si la cantidad de gas y la presión permanecen constantes, el cociente entre el volumen y la temperatura siempre tiene el mismo valor:

\frac{V}{T}=k

Suponiendo un cierto volumen de gas V1 que se encuentra a una temperatura T1 al comienzo del experimento, al variar el volumen de gas hasta un nuevo valor V2, entonces la temperatura cambiará a T2, y se cumplirá:

\frac{V1}{T1}=\frac{V2}{T2}

En este caso, sabes:

  • V1= 3.5 L
  • T1= 25 °C=298 °K (siendo 0°C=273°K)
  • V2=?
  • T2=7 °C=280 °K

Reemplazando:

\frac{3.5 L}{298 K}=\frac{V2}{280 K}

Y resolviendo obtienes:

V2=280 K*\frac{3.5 L}{298 K}

V2= 3.29 L

<u><em>El volumen del gas en el recipiente es 3.29 L si se disminuye la temperatura a 7°C</em></u>

Differentiate between Fundamental unit and derived unit​
Serga [27]

Answer:

Fundamental Units are the units which are independent of any other unit.

They do not depend on any other physical quantity for their measurements .

Derived Units are derived from Fundamental Units.

They are are products and/or ratios of the fundamental quantities that exist in a system of units.
