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.
Notice the lack of asteroids with periods exactly Â½, 1/3 or Â¼ of Jupiter's â Jupiter has cleared gaps in the asteroid belt, knocking out asteroids that used to live there. Once pushed out of the asteroid belt, these asteroids either crashed into a planet or moon or were flung out of the solar system altogether. Asteroids with unusual orbits are the result of Jupiter's gravity, tugging the asteroid out of its original orbit into a new one.
