Answer:
0.628 M.
Explanation:
In order to solve this problem we need to keep in mind the<em> definition of molarity</em>:
- Molarity = moles / liters
We are given both the <em>number of moles and the volume of solution</em>, meaning we can now proceed to <u>calculate the molarity</u>:
- Molarity = 0.220 mol / 0.350 L
Isolated systems does not allow any matter or energy to be exchanged.
Answer:
B) weathering and erosion
Explanation:
The two processes responsible for changing metamorphic and igneous rocks into sedimentary rocks is weathering and erosion.
Weathering is the defined as the physical disintegration and chemical decomposition of rocks to form sediments and soils.
Erosion is the removal of weathered materials from the surface of the earth.
The process of erosion and weathering serves to convert igneous and metamorphic rocks into sediments by which a sedimentary rock is formed.
Mixture: matter than is composed of two or more substances that can be separated by physical means (ex; let's say you have a jar of red and blue marbles. this is a mixture. You can separate the colors with your hands (physical means.))
Compound: a substance in which two or more atoms are chemically combined in a fixed proportion (ex: water is a compound that consists of the element hydrogen and the element oxygen).
It's a type of homogeneous mixture which has a dissolved substance particle size of less than 1 nanometere.
