In a few sentences, describe how sedimentary rock forms.
photoshop1234 [79]

answer:

sedimentary rock is formed when rocks start to weather away causing them to loosen. **weathering is the breaking down of rocks, soils, minerals, and artificial materials through contact with water, atmospheric gases, and biological organisms.** sedimentary rocks are formed from older rocks. the pieces of broken rocks are then transported (through water.) and over time the layers will become compacted (salt crystals 'glue' the layers together.)

good luck :)

i hope this helps

have a nice day!

How many moles of silver atoms are there in 1. 8 x 1020 atoms of silver?.
Lilit [14]

Answer:

Taking into account the definition of avogadro's number, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.

First, you have to know that it is called Avogadro's Number or Avogadro's Constant. By Avogadro's number it is understood the number of elementary entities (that is, of atoms, electrons, ions, molecules) that exist in a mole of any substance. Its value is 6.023×10²³ particles per mole.

Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.

Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ atoms are contained in 1 mole of silver, then 1.8×10²⁰ atoms are contained in how many moles of silver?

amount of moles of silver= (1.8×10²⁰ atoms × 1 mole)÷ 6.023×10²³ atoms

amount of moles of silver= 2.98×10⁻⁴ moles

Finally, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
