Those compounds, hydrochloric acid and calcium, produce hydrogen (gas)
It gives the product as calcuim-sulphate.
Water vapor is produced when baking soda and hydrochloric acid are mixed.
ozone
Carbon Dioxide
Carbon dioxide gas is produced when calcium carbonate and hydrochloric acid are mixed. This reaction occurs as the acid reacts with the calcium carbonate, releasing carbon dioxide gas as a byproduct.
Magnesium nitrate (salt) and water are produced.
When iron oxide and sulfuric acid are mixed, iron sulfate and water are produced. The chemical reaction can be represented as Fe2O3 + H2SO4 → Fe2(SO4)3 + H2O.
Hydrogen gas was produced when zinc and hydrochloric acid were mixed. This is because when zinc reacts with hydrochloric acid, hydrogen gas is released as one of the products of the reaction.
When hydrochloric acid is mixed with an alkali, such as sodium hydroxide, water and a salt are formed. There is no gas produced in this reaction.
Formic acid is the organic molecule necessary to detect mixed acid fermentation by bacteria. It is produced as a byproduct of this fermentation process and can be detected through various chemical tests.
Iron oxide + Sulphuric Acid iron sulphate + water
CaCO3 + 2HCl -> CaCl2 +H2O +CO2
