Answer:
Explanation:
Homogeneous mixture is a mixture in which the components of the mixture are in the same proportion throughout any sample extracted from the mixture while an heterogeneous mixture is a mixture in which the components of the mixture differ in term of proportion when different samples of the mixture are extracted and compared.
For example, a sandy water will have some parts (usually the bottom) of the mixture with more sand than other parts of the mixture, hence, it (sandy water) is a heterogeneous mixture. While salty and ocean water has it's salt dissolved in the same proportion throughout the water in the mixture, hence salty and/or ocean water is a homogeneous mixture.
Sandy water can be separated by filtration (i.e using a filter paper to separate the sand from the water when the mixture is poured over a filter paper) while salty and ocean water can be separated by distillation (i.e boiling of the mixture so the water molecules can boil and move through a tube as gas or steam into another container where they are cooled and converted back to liquid or water while leaving the solid salt component of the mixture in the boiling tube).
Answer:
A) 8.51 × 10²⁴
Explanation:
1. Gather all the information
2H₂S + SO₂ ⟶ 3S + 2H₂O
n/mol: 9.42
2. Calculate the moles of S atoms
The molar ratio is 3 mol S:2 mol H₂S
3. Calculate the atoms of S
The information that the third quantum number of an electron gives is the direction the electron in spinning. That is option A.
<h3>What are quantum numbers?</h3>
Quantum number are those numbers that are used to specify the properties of the atomic orbitals and the electrons in those orbitals.
The types of quantum numbers include the following:
The third quantum number is shows the direction of the electron while spinning through specifying its angular momentum.

Answer:
La reacción se convierte en reversible porque en un recipiente cerrado el gas no escapa y puede reaccionar con el óxido
Explanation:
Basados en la reacción:
3Fe + 4H₂O → Fe₃O₄ + 4H₂(g)
<em>3 moles de hierro con 4 moles de agua producen 1 mol de óxido de hierro y 4 moles de hidrógeno (gas)</em>
Cuando la reacción se está produciendo con un recipiente abierto, todo el gas de hidrógeno está escapando a la atmósfera y no habrá forma de que reaccione con el óxido de hierro.
Pero, si el recipiente está cerrado, el hidrógeno no podrá escapar y podrá reaccionar con el óxido de hierro, así:
Fe₃O₄ + 4H₂(g) → 3Fe + 4H₂O
De esta manera,
<h3>la reacción se convierte en reversible porque en un recipiente cerrado el gas no escapa y puede reaccionar con el óxido</h3>
