El arsénico puede provocar cáncer en pulmón y piel, e inclusive puede causar otros tipos de cánceres. Se observa una mayor fuerza de asociación entre la exposición crónica al arsénico y los cánceres de piel,El arsénico es un elemento químico de la tabla periódica que pertenece al grupo de los metaloides, también llamados semimetales, se puede encontrar de diversas formas, aunque raramente se encuentra en estado sólido. Se conoce desde la antigüedad y se reconoce como extremadamente tóxi ve
Símbolo: As
Configuración electrónica: [Ar] 3d104s24p3
Masa atómica: 74.9216 u ± 0.00002 u
Número atómico: 33
Electrones por nivel: 2, 8, 18, 5 (imagen)
Grupo, período, bloque: 15, 4, p.
The correct formula : BeSO₄
<h3>Further explanation</h3>
Chemical formula shows the composition number of the constituent atoms
Polyatomic ion consists of 2 or more ions
The equal charge of the two ions will cancel each other out, while the different charges of the two ions will be crossed each other
Be²⁺ (monatomic ion) has a positive charge of +2, while SO₄²⁻ (polyatomic ion) has a negative -2 charge, so that the two charges with the same magnitude but with different charges cancel each other out so that the compound form is BeSO4
Balanced chemical equation for the reaction between sulfuric acid & solid aluminum hydroxide to form liquid water and a soluble salt is 3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those in which all entities are present in same amount on both sides of the chemical equation.
Balanced chemical reaction for the given compounds will be shown as:
3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O
Above chemical equation is the balanced equation as all atoms are present in same amount on the left side as well as on the right side of the reaction.
Hence balanced equation is 3H₂SO₄ + 2Al(OH)₃ Al₂(SO₄)₃ + 6H₂O.

In a distillation model, it is better to let the cold water enter the bottom of the condenser and exit at the top because this can lead to a better cooling effect.
When water enters from the bottom, they will stay longer in the condenser, thus the vapor in the condenser can be cooled back into liquid faster.
In addition, this method can also save the amount of water used, since they water can stay longer in the condenser.
The right answer is the last one hope this helps your very welcome
