Answer 1

Тому що в повітря потрапляють Погані речовини, та змішується з ним. Вода так само може змішуватись З брудом

Answer 2

Are Air and Seawater Mixtures?

Air and seawater are not considered mixtures in the traditional sense. Let's explore the composition of air and seawater to understand why.

Composition of Air:

Air is a mixture of gases, primarily nitrogen (N2), oxygen (O2), carbon dioxide (CO2), and traces of other gases such as argon (Ar), neon (Ne), helium (He), and methane (CH4). The proportions of these gases can vary slightly depending on factors such as location and altitude. The composition of dry air is approximately 78% nitrogen, 21% oxygen, 0.04% carbon dioxide, and the remaining 1% consists of trace gases.

Composition of Seawater:

Seawater is a complex solution that contains various dissolved substances. The primary components of seawater are water (H2O) and dissolved salts, such as sodium chloride (NaCl), magnesium chloride (MgCl2), and calcium carbonate (CaCO3). Additionally, seawater contains dissolved gases, organic matter, and various trace elements. The salinity of seawater, which refers to the concentration of dissolved salts, is typically around 3.5%.

Conclusion:

While both air and seawater consist of multiple components, they are not considered mixtures in the traditional sense. Air is a mixture of gases, while seawater is a solution containing water and dissolved salts.
