Oxygen in the air reacts with heated sphalerite to form zinc oxide and sulfur dioxide.
The word equation for heated mercury is "mercury reacts with oxygen to form mercury oxide."
Magnesium, Iron, Copper,sodium and potassium
Iron and Zinc
martinium reacts fast while wellemium still reacts but much slower
When magnesium is heated in air, it reacts with oxygen to form magnesium oxide. The total mass of the system, which includes the magnesium and the oxygen it reacts with, remains the same according to the Law of Conservation of Mass.
When silver reacts with a base, such as sodium hydroxide, it forms silver oxide and hydrogen gas. The silver oxide is then converted back to silver metal when heated.
The metal powder that turns black when heated in an open dish is likely to be magnesium. This is due to the formation of magnesium oxide on the surface of the metal powder when it reacts with oxygen in the air during heating.
When HCl (hydrochloric acid) mixes with heated copper, the copper reacts with the acid to form copper(II) chloride and hydrogen gas. The reaction releases heat and the copper may also appear to be dissolved as it reacts with the acid.
The compound formed when magnesium reacts with sulfur is magnesium sulfide (MgS).
Sodium reacts vigorously with oxygen, especially when heated, to form sodium oxide (Na2O). This reaction is exothermic and can produce a bright yellow-orange flame. However, it is not as violent as some other alkali metals like potassium or cesium.
One example is hydrogen peroxide, which reacts more effectively when heated in certain chemical reactions. Heating can accelerate the reaction by providing energy to break certain bonds in the molecules.
