Describe how you could show that a compound is an acid
Charra [1.4K]
An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic.

soldier1979 [14.2K]

Hello! My name is Zalgo and I am here to help you out today. The most common form of matter in the universe would be "Plasma".  Plasma is gas that is heated a lot so it turns into high energy (high energy would be said "Plasma").

I hope that this helps! :D

A rock can be broken down into different kinds of substances by physical processes. No chemical reactions are needed to separate
denpristay [2]

Answer:

I believe the correct answer is a mixture. Most rocks are just different compounds or elements somewhat fused through heat and pressure. The substances are not chemically bonded together which means that they all retain their chemical identity and therefore can be separated by breaking them up. A good example of this is granite where you can see the different compounds that got fused together and can falls apart when you grind it. I hope this helps. Let me know if anything is unclear.

Explanation:

HOPE THIS HELPS :)

El osmio es un metal sólido que tiene una densidad
pentagon [3]

Respuesta:

4.42 × 10⁻⁶ m³

Explicación:

Paso 1: Información provista

  • Densidad del osmio (ρ): 22600 kg/m³
  • Masa de osmio (m): 100 g

Paso 2: Convertir 100 g a kilogramos

Usaremos el factor de conversion 1 kg = 1000 g.

100 g × 1 kg/1000 g = 0.100 kg

Paso 3: Calcular el volumen ocupado por 0.100 kg de osmio

La densidad es una propiedad intensiva, igual al cociente entre la masa y el volumen.

ρ = m/V

V = m/ρ

V = 0.100 kg / (22600 kg/m³) = 4.42 × 10⁻⁶ m³
