Please help!! A 22.4 L Sample of which of the following substances, at STP, would contain Avogadro’s number of particles?
A. Phosphorus B. Mercury C. Nitrogen

Answers

Answer 1
The “22.4 L = 1 mole” principle holds only for gases (and even then, technically only for ideal gases). In any case, the only element given here that would be a gas at STP would be nitrogen. So, the answer would be choice C.
Answer 2
I believe that the correct answer is C

Laura jala un trineo una distancia de 2000 cm usando una cuerda, con una tensión constante de 80 N. La tarea requiere de 800 J de trabajo, ¿qué ángulo forma la cuerda con el suelo?

Answers

Respuesta:

60°

Explicación:

Paso 1: Información dada

Distancia recorrida (d): 2000 cmFuerza aplicada (F): 80 NTrabajo realizado (W): 800 J

Paso 2: Convertir "d" a metros

Usaremos el factor de conversión 1 m = 100 cm.

2000 cm × 1 m/100 cm = 20 m

Paso 3: Calcular el ángulo entre la cuerda y el suelo (θ)

W = F × d × cosθ

800 J = 80 N × 20 m × cosθ

θ = 60°

What is the mass of zinc required to combine with 0.5 mol of chlorine to produce zinc chloride,ZnCI[subscript 2]?

[Relative atomic mass : Zn = 65]

Answers

Answer:

16.25g

Explanation:

Equation for the reaction = Zn + 2Cl = ZnCl2

1 molecule of Zn = 2 molecule of Cl

x mole of Zn = 0.5mol of Cl

mole of Zn = 0.25mol

mass of Zn = 0.25 * 65 = 16.25g

The mass of zinc required to combine with 0.5 mol of chlorine to produce zinc chloride is 16.25g.

What is mass?

Mass is the quantity of matter in a physical body.

The reaction is Zn + 2Cl = ZnCl₂

The ratio of moles of Zn and Cl

1 : 2

m, mol of Zn is equal to 0.5 mol of Cl

Moles of Zn = 0.25 mol

Multiply the mole of Zn and the relative atomic mass of Zn

Mass of Zn = 0.25 × 65 = 16.25 g.

Thus, the mass of zinc is 16.25 g.
