Zinc would have no effect on litmus paper. It is affected by solutions of acids and alkalis. I wonder if you have some acid and you are adding the zinc to that? If so, eventually, if there is enough zinc, the acid will be neutralized so instead of being pink with the acid, the litmus will go a purplish colour.
Red litmus paper will turn blue.
it turns litmus blue to red

Magnesium is a metal
Magnesium plus oxygen becomes magnesium oxide.
Magnesium becomes heavier after it is burnt. This is because the magnesium has chemically bonded with oxygen to form magnesium oxide. The oxygen adds the extra weight.
Magnesium oxide (MgO) is formed. When a piece of magnesium ribbon is burnt it reacts with oxygen in air according to the chemical equation: 2Mg(s) + O2(g) → 2MgO(s) The magnesium burns in a bright white light and the resulting magnesium oxide is in the form of a white powder.
The colour when coal is burnt is white,when it become ash
When Magnesium chloride is burnt in a Bunsen flame, it imparts no colour in the flame.
Burnt Magnesium ribbon ----> MgO (magnesium oxide)(basic in nature) When added to water, it forms its hydroxide MgO+H2O ----> Mg(OH)2 (which is a base) when added to litmus paper or litmus solution....it will give a light blue colour
Yes. Magnesium burns in air brightly giving Magnesium oxide, witch is a chemical change.

If it is burnt with a gas such as oxygen then yes
It forms magnesium oxide. :)

One - Magnesium Oxide (MgO)
a bright light is created and it then creates magnesium oxide
If completely burnt (in excess of oxygen), all the magnesium will be converted to magnesium oxide.
