When adding sugar to tea, it was observed that the sugar kept dissolving. After a

The molecule of  mixture  cannot be seen hence, it will be considered as homogeneous mixture.

<h3>What is molecule?</h3>

A molecule is just a collection of more than two atoms bound together by chemical bonds; depending on the context, the phrase doesn't have to include ions that meet this requirement.

<h3>What is homogeneous mixture?</h3>

Solids, liquids, as well as gases, can all be homogeneous mixtures. Through, they have almost the same look and chemical makeup.

When sugar will be dissolved, the sucrose molecules get separated from one another. The materials that make up individual molecules stay together like sucrose molecules sucrose molecules, so the molecule will not break up.

Therefore mixture can be considered as molecule and homogeneous mixture.

6. El oxígeno gaseoso se calienta a presión constate de 50 °C a 300 K. Se conoce que inicialmente el volumen del sistema era de
frez [133]

Answer:

El volumen final del sistema es 1.2L

Explanation:

La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:

V₁/T₁ = V₂/T₂

<em>Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.</em>

<em />

Reemplazando:

V₁ = 1.3L

T₁ = 50°C + 273.15K = 323.15K

V₂ = Incógnita

T₂ = 300K

1.3L/323.15K = V₂/300K

1.2L = V₂

<h3>El volumen final del sistema es 1.2L</h3>

valentina_108 [34]

The spontaneous disintegration of a nucleus into a slightly lighter and more <u>radioactive </u>nucleus is accompanied by the emission of particles, electromagnetic radiation, or both.

Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei into atomic nuclei to shape greater energetically strong atomic nuclei.

Radioactive decay is a tremendously exoergic, statistically random, first-order system that occurs with a small amount of mass being converted to strength.

Spontaneous disintegration of a radionuclide with the emission of lively particles or radiation, consisting of alpha or beta debris or gamma rays.

I guess you could call them that. In chemistry, we call them Metalloids though.
