a. H2Te b. H2O c. H2S d. H2Se Acid and Bases: Acids are those substances that give hydrogen ions in the water while bases give hydroxide ions in water. A strong acid will fully dissociate into its ions, while a weak acid will only partially dissociate, giving a lesse...
Melamine formaldehyde is stain-resistant and resistant to strong solvents and water. Melamine formaldehyde is affected by alkalis and concentrated acids–such as sulphuric acid (H2SO4) and oxalic acid (H2C2O4). Melamine formaldehyde utensils are not microwave safe. They absorb radiation, which causes ...
