The limiting reactant here is P4O10 . The percent yield of the product is caculated as 33.3%.

<h3>What is the limiting reactant?</h3>

The limiting  reactant is the reactant that is in a minute quantity.

Number of moles of P4O10 =  85.5 g/284 g/mol = 0.3 moles

Number of moles of H2O =  74.9 g / 18 g/mol = 4.2 moles

From the reaction equation;

1 mole of P4O10 reacts with 6 moles of H2O

x moles of P4O10 reacts with 4.2 moles of H2O

x = 0.7  moles

Hence, P4O10 is the limiting reactant.

1 mole of P4O10 yields 4 moles of H3PO4

0.3 moles of P4O10 yields

0.3 moles * 4/1 = 1.2 moles

Mass of the H3PO4 = 1.2 moles * 98 g/mol = 117.6 g

Percent yield = 39.2 g/117.6 g * 100/1 = 33.3 %

Number of charge = 5018 C

<h3>Further explanation</h3>

Given

1000 C of charge for x grams of copper

Required

Number of charge

Solution

Faraday's Law :

\tt W=\dfrac{e.i.t}{96500}\\\\W=\dfrac{e.Q}{96500}

For 1000 C, W = x grams

\tt x=\dfrac{1000.e}{96500}=0.0104e

For 5x grams :

\tt 5x=\dfrac{e.Q}{96500}\\\\5\times 0.0104e=\dfrac{e.Q}{96500}\\\\Q=\dfrac{96500\times 5\times 0.0104e}{e}=5018~C

What is the difference between random decay and theoretical?
denis-greek [22]

Answer:

Spontaneous and random. Decay is called spontaneous because the occur on their own and are unaffected by external factors like temperature, pressure, and many more. Decay is called random because we cannot determine the rate at which it decays but can only determine the probability of the decay.Oct 21, 2015

What are humic acids?
Dominik [7]

Answer:

Los ácidos húmicos son restos de vida orgánica totalmente descompuestos. Son moléculas de cadena larga que son de alto peso y de color marrón oscuro. No son un solo ácido. Más bien, "ácido húmico" es un término amplio que se refiere a una mezcla compleja de muchos ácidos diferentes que son solubles en soluciones alcalinas. Existen de forma natural como parte del ciclo de vida de la naturaleza en suelos, océanos y arroyos. Cómo se forman?

Cuando las plantas y los animales mueren, sus moléculas quedan disponibles en el suelo para ser utilizadas por otros organismos. Bacterias, hongos, protozoos, lombrices de tierra e incluso insectos consumen el material fresco. Después de largos períodos de tiempo, cuando la materia en descomposición se ha comido y transformado a través de varios ciclos, lo que queda es un material resistente que resiste una mayor descomposición, llamado humus. (Este proceso se conoce como "humificación"). El humus es un término general que se refiere a compuestos estables y altamente complejos que son resistentes a una mayor descomposición. Y el humus consta de tres componentes: ácidos húmicos, ácidos fúlvicos y humus. Los ácidos húmicos y fúlvicos han demostrado ser invaluables para entornos de suelo saludables, particularmente por sus contribuciones a la estructura del suelo y la transferencia de nutrientes entre el suelo y las plantas.
