Answer:
Option C; NONE.
Explanation:
A chemical reaction forms new chemicals called the products from the initial chemicals called the reactants. The reaction between an acid and a base is called neutralization, and the products formed are water and a salt.
When hydrochloric acid and sodium hydroxide is mixed together, they interact, and result in salt and a release of heat.
The result of the interaction of these two highly aggressive compounds is table salt and water, these resulting compounds are ultimately harmless, and even beneficial, to human beings.
Therefore, NO TOXIC GAS WOULD BE FORMED BY MIXING HYDROCHLORIC ACID WITH SODIUM HYDROXIDE.

4.42 × 10⁻⁶ m³
Explicación:
Paso 1: Información provista
- Densidad del osmio (ρ): 22600 kg/m³
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
Answer:
Explanation:
We know from laws of diffusion that .
In the given question , it is said that temperature is same in both the cases .
So for rate to become half , molecular mass must be 4 times,<em>ie,</em>
Mass of required gas = 4×mass of He=4×4=16.
Therefore the gas is
You are a cell membrane.
