Space probes have shown that there are mountains, dry river-valleys and volcanoes on Mars. Scientists believe Mars, like Earth, has all three types of rock: igneous, metamorphic and sedimentary. Using the information above, explain why.

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →

How many moles of magnesium is 3.01 x10^22 atoms of magnesium?

Weight is a measure of: inertia force matter mass
