A chemist dissolves silver nitrate (AgNO₃) in water. He also dissolves ammonium chloride (NH₄Cl) in water. He mixes the two solu

zhuklara [117]

Answer:

c. AgNO₃(aq) + NH₄Cl(aq) ->AgCl(s) + NH₄NO₃(aq)

Explanation:

We have to follow the solubility rules to check the states of each compound.

-) All the cholride salts are soluble EXCEPT those also containing: lead, silver or mercury. $Pb^+2~Ag^+~Hg_2^+^2$

-) All the nitrate $NO_3$ and ammonium salts $NH_4^+$ are soluble.

With this in mind $AgNO_3$ , $NH_4Cl$ and $NH_4NO_3$ would be soluble, so we have to use the aqueosus state (aq).

The $AgCl$ then would have a solid state (s).

Romashka-Z-Leto [24]

Answer:

Aristotle's Model :

geocentric

planets fixed on nested spheres

Ptolemy's model:

geocentric

planets fixed on epicycles

accurately predicted the positions of the planets

Explanation:

Let's begin by the fact both models are geocentric and make a brief explanation of them:

Aristotle's Model :

Aristotle built his model based on observations and philosophical assumptions, not on measurements or calculations, then he mistakenly thought the Earth was the center of the universe.

So, according to this model, the universe was spherical and finite, with the Earth immobile at its center, composed of the four fundamental elements (made up of spherical layers): ground, water, air and fire; and the Sun along with the fixed planets in their respective concentric spheres (also called nested spheres) revolving around the Earth.

Ptolemy's model:

Ptolemy's model of the universe was also geocentric, placing the Earth motionless in the center of the known universe and was the accepted model for a long time during the Middle Ages.

In this sense, ccording to Ptolemy's model of the universe our planet remains stationary while the other planets, the Moon and the Sun describe complicated orbits around it (called epicycles).

However, this model predicted with an acceptable accuracy for that time the motion of the known planets, until Copernicus appeared with the revolutionary Heliocentric model.

MATCH THE TERM WITH THE DEFINITION:

arlik [135]

Weathering definition= wear away or change the appearance or texture of (something) by long exposure to the air.

Erosion definition= the process of eroding or being eroded by wind, water, or other natural agents.

Deposition definition= the action of deposing someone, especially a monarch.

these definitions are out of my textbook but in my own words.
