Barium chloride and magnesium sulfate are chemical compounds, not "changes".
The magnesium burns readily in air to produce a white ash which is magnesium oxide. This is due to the "oxidation" of the metal.
Sublimation of any pure substance such as ammonium chloride by definition is a physical change, because sublimation is defined as passage of substance from the solid to the gas phase without passing through an intermediate liquid phase.
When chemical changes occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. Eg of a chemical change is the reaction between sodium hydroxide and hydrogen chloride to produce sodium chloride, or common salt.
No. Burning magnesium, or burning anything for that matter, is a chemical change. The magnesium reacts with oxygen to form magnesium oxide, and to some degree reacts with nitrogen to form magnesium nitride.
chlorine atom will first convert to the gaseous chlorine atom which will then add one electron to form chloride ion.
In presence of chlorine, sodium atoms will discharge electrons to give sodium ions to combine with chloride ions followed by forming a lattice of sodium chloride.
Yes. Magnesium metal reacts in hydrochloric acid to form magnesium chloride and hydrogen gas.
Barium chloride and magnesium sulfate are chemical compounds, not "changes".
potassium chloride
"ide" as in lithium chlorIDE
It is a chemical change.2NaCl --> 2Na + Cl2
Chemical
They combine to make sodium chloride, commonly known as table salt.
because when sodium combines with chlorine, the properties change.
It is a chemical change, where a chemical such as oxygen or chlorine combines with a metal, forming an oxide or chloride of that metal.
The magnesium burns readily in air to produce a white ash which is magnesium oxide. This is due to the "oxidation" of the metal.
