Particles in a solution are mixed together evenly. ... This makes the solution look like one substance. Particles in a mechanical mixture are not mixed evenly. The particles stay together in groups.
The answer is C. A projectile is an object in motion from space that enters the earth’s atmosphere. When it gets to the earth, it is pulled by the force of earth's gravity. As it enters earth’s atmosphere, its inertia determines its path. The mass of the object determines its inertia. The more mass it has the higher its inertia which causes it to have a longer curvature when pulled by earth’s gravity.
Answer:
2.14 x 10^-10 M
Explanation:
[H+] = 10^(-pH) = 10^-9.67 = 2.14 x 10^-10 M
Scientists use special tools to do their work. They gather data, or information, as they seek to learn about the world. In order to solve problems they must record data that is accurate and organized. This is an important part of the scientific method.
Chemical substances can exist as solids, plasma, and gases so I guess it is none of the above.
