Plasma is the fourth state of matter. Plasma occurs at extreme high temperatures. It is found in stars, lightning, and neon lights. Plasma is the most commonly found matter in the universe, even though its not common on earth.
In crystalline solids, the particles are arranged in a repeating, three dimensional pattern called a crystal. Some forms of crystalline solids are table salt, sugar, sand, and snow. Diamonds are also crystalline solids.
Gas is a matter that does not have a definite shape or volume.The particles in gas are much father apart than those in a liquid or solid. Gas particles move at high speeds in all direction.
Plasma is different because it can only exist in extremely high temperatures. It is not common on Earth, like the other states of matter. It is only common in the universe. Plasma is found in a lot of things in space. Plasma is not bound to one atom, so it is free. Plasma is formed by adding more heat to the molecules of gas. Eventually, the molecules are moving so fast, that they break apart from their atoms, and then they are positively charged ions, or plasma.
Answer:
0.246M
Explanation:
0.123M x 2 = 0.246M
Due to Sr(OH)2 has the coefficient of 2.
The masses are always equal. Since matter can not be created nor destroyed, you will have the same amount of mass as you did before the reaction as you do after.
Answer:
Ne with eight dots
Explanation:
On the periodic table, Neon is in group 8A. The group can be used to determine the number of valence electrons.
The dots in the Lewis structure diagram represent the number of valence electrons.
The average distance a gas particle travels between collisions (with the wall or another particle is called the mean free path.
According to the kinetic theory of gases, the particles of a gas (atoms or molecules) have the highest kinetic energy and travel at high speeds. At standard temperature and pressure, a gas particle can reach speeds of about 470m/s.
Despite the high speeds gas particles travel, it still takes a while for the fragrance of an opened perfume to diffuse to the other end of the room. This is because when moving, the molecules do not have a free path. They constantly collide with other particles and the walls of the container and change direction randomly. The average distance a single particle can travel without colliding with other particles, or the wall of the container is called the mean free path.
