Answer: pH = 2,897 , basic![[H+][OH-] = 10^{-14} ==> [H+] = \frac{10^{-14}}{7,89*10^{-12} } =\frac{1}{789} \\pH= -lg([H+]) = 2,897 \\pH basic](https://tex.z-dn.net/?f=%5BH%2B%5D%5BOH-%5D%20%3D%2010%5E%7B-14%7D%20%3D%3D%3E%20%5BH%2B%5D%20%3D%20%5Cfrac%7B10%5E%7B-14%7D%7D%7B7%2C89%2A10%5E%7B-12%7D%20%7D%20%3D%5Cfrac%7B1%7D%7B789%7D%20%5C%5CpH%3D%20-lg%28%5BH%2B%5D%29%20%3D%202%2C897%20%5C%5CpH%3C7%20%3D%3D%3E%20basic)
Explanation:
They look like gases plasmas have no fixed shapes or volume and are less dense tan solids or liquids
Galaxies are the lump of matter. The shape of major galaxies is spiral shape. Thus, the given statement is false.
<h3>What are the shapes of galaxies?</h3>
The galaxies are the lump of dust and mass, held together by the gravitational force. The galaxies are continuously moving in the universe.
The formation of galaxies is believed to be due to the force of attraction between the components.
The shape of major galaxies is assumed to be spiral-shaped, however, the irregular shape galaxies are also present.
Thus, the given statement about the shape of galaxies is false.

The phenomenon is known as the Greenhouse Effect.
When the sun's energy reaches the Earth, some is reflected into space, but the rest is absorbed by gases and warms the atmosphere. The phenomenon is known as the Greenhouse Effect.
