8 0

The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.

The moles of reactant and product in a chemical reaction to the whole number ratio is given by the stoichiometric coefficient of the balanced chemical equation.

Given the equation: HCl + Na2SO4 → NaCl + H2SO4, if you start with 8 moles of hydrochloric acid, how many grams of sulfuric acid
Simora [160]

Answer:

392g sulfuric acid are produced

Explanation:

Based on the balanced equation:

2HCl + Na2SO4 → 2NaCl + H2SO4

<em>2 moles of HCl produce 1 mole of sulfuric acid</em>

<em />

To solve the problem we need to find the moles of sulfuric acid produced based on the chemical equation. Then, using its molar mass -<em>Molar mass H2SO4 = 98g/mol- </em>we can find the mass of sulfuric acid produced:

<em>Moles sulfuric acid:</em>

8mol HCl * (1mol H2SO4 / 2mol HCl) = 4 mol H2SO4

<em>Mass sulfuric acid:</em>

4mol H2SO4 * (98g / mol) =

392g sulfuric acid are produced

The electron configuration of an element is 1s22s22p4.
MissTica

The likely thing which happens when two atoms of this element move toward each other is covalent bonding.

<h3>What is Covalent bonding?</h3>

This involves the atoms of element sharing electrons in order to achieve a stable octet configuration.

The element is oxygen which has an atomic number of 8 and needs two electrons to complete its outermost shell which results in the formation of two covalent bonds.

En que se fundamento Moseley para describir la tabla periódica actual?
Burka [1]

Answer:

La tabla periódica de moseley fue una manera de dar solución a esta problemática, ya que nos permite tener a la mano todos los elementos que se han descubierto hasta la actualidad y sus propiedades químicas más resaltantes.

A continuación se Describe una linea del tiempo de la creación de la tabla periodica:

1820 -  se crean las tríadas de Dobereiner.  

1863 - se crea el cilindro de chancourtois.  

1864 - se crean las octavas de newlands.  

1869 - se crea el primer prototipo de la tabla periódica.  

1914 - se fórmula la ley periódica moderna por Moseley.
