Answer:
B. a state in which the forward and reverse reactions are proceeding at equal rates
Explanation:
"Chemical equilibrium is the state of a chemical system at which a constant concentration of products and reagents is present. Reactions, which take place in homogeneous solutions, seem to have come to rest because no changes in concentrations of the participating substances can be determined. Substance turnover occurs only on the particle level, which is why chemical equilibrium is also referred to as dynamic equilibrium."
Similarities:
they both made sediment into soil
they both form the earth
they both made sediments have cracks
differences:
physical is reliant usually on contact with atmospheric condition
chemical transforms rocks into sediments while physical only breaks it down
chemical uses chemical reactions

Answer:
properties
Explanation:
The properties of matter are the various ways in which matter behaves under certain circumstances.
Various substances have different volumes and shapes. These differences account for the various properties of matter.
1) D. An element
2) D. Suspension
3) A. Iodine
4) A. Atoms of the same element
Answer:
The metalloids are a unique group of elements that share properties of both metals and nonmetals. They're also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.
