Single-Replacement Reactions 1. Copper reacts with silver nitrate to form silver metal and copper(II) nitrate. copper metal + silver nitrate silver metal + copper(II) nitrate 2. Zinc metal reacts with hydrochloric acid to produce zinc chloride and hydrogen.
The first is by composition. The typical composition of an asteroid depends on its distance from the Sun. At the outer edges of the asteroid belt, that is between three and three and a half times further from the Sun than the Earth, over eighty percent of the asteroids are known as C-type.rom piles of 'rubble' to complex mixtures of metals, and carbon and silicon compounds, asteroids are not just dull grey lumps of cratered rock... We find that asteroids are fascinating objects, varying in composition and shape.
Asteroid Belt. The asteroid belt is situated between the orbits of Mars and Jupiter around 280 million miles (450 million km) from the sun. There are millions of asteroids residing in this area ranging from 600 miles (950 km) in diameter, all the way down to particles of dust.steroid Belt Facts. 1  There are 200 objects in the asteroid belt larger than 60 miles (100 km) in diameter and almost 1 million objects over 1 km in diameter. 2  The average surface temperature of an asteroid is -73C (-100F).
