acid precipation
It contributes by the burning of fossil fuels like coal that realeases sulphur
Burning creates oxides such as C02 and nitrous oxides. These react with the water in the air (H20), combining with the hydrogen in the water to form acids: carbonic acid and nitric acid respectively.
Hydrogen sulfate would be an alternate name for sulfuric acid, H2SO4. It is a very strong acid.
Two of the gases that form from burning petrol are nitrogen and carbon dioxide. These are two gases that are contributing to the acid rain affect.
If it was a reaction between sodium hydroxide and an unknown acid the acid would be nitric acid (HNO3)
You would see bubbles (effervescence) of Hydrogen gas being given off as the reaction happens.Magnesium + Hydrochloric acid ------> Magnesium Chloride + HydrogenMetal + acid ------> Metal Salt + Hydrogen
These gases are sulfur dioxide and nitrogen dioxide.
Magnesium metal would displace hydrogen from Sulphuric acid and form Magnesium sulphate anh Hydrogen gas would be liberated.
HPO4 does not exist. HPO42- would be the dibasic form of phosphoric acid and be the hydrogen phosphate ion. H3PO4 also exists and is phophoric acid. So if two moles of NaOH were reacted with phosphoric acid 2Na+ HPO42- would be formed disodium hydrogen phosphate.
Hydrochloric acid itself is a chemical, i assume you mean elements, these would be Hydrogen and Chlorine. Also it is important to note there is water present which contains Hydrogen and Oxygen. So the three elements present in Hydrchloric acid would be Hydrogen, Chlorine and Oxygen.
hydrogen chloride is an acid
