How can black chert be distinguished form black limestone?
If you have a small sample bottle of dilute hydrochloric acid, the limestone will fizz as it is calcium carbonate and will dissolve in the acid, releasing carbon dioxide gas. The same acid will not react with the inert silica of a black chert. Sometimes chert and limestone are finely inter-bedded and the acid will pick out the limestone bands!
What is a colorless mineral that's powdered form bubbles with acid?
The colorless mineral you're referring to is likely calcite. When powdered calcite is combined with acid, such as hydrochloric acid, it reacts to produce carbon dioxide gas, which causes the characteristic bubbling or fizzing. This reaction is a key identification test for calcite in mineralogy. Its colorless form is often found in sedimentary rocks like limestone.
How would the electrons produced in a cathode ray filled with neon gas compare with the electrons produced in a cathode ray filled with chlorine gas?
the results are the same regardless of the gas
What happens to iron pyrite when it burns?
When iron pyrite (FeS₂) burns, it undergoes a chemical reaction with oxygen, resulting in the formation of iron oxide (Fe₂O₃) and sulfur dioxide (SO₂) gas. The burning process releases heat and can produce a bright flame due to the oxidation of sulfur. This reaction can also lead to the generation of sulfuric acid when SO₂ reacts with moisture in the atmosphere, contributing to environmental concerns such as acid rain.
What raw materials does England produce?
Oil and natural gas. Coal Iron Ore. Limestone. Small amounts of lead, tin and gold. Salt
Which Gas is made when limestone reacts with an acid?
Carbon dioxide gas is produced when limestone, which contains calcium carbonate, reacts with an acid. This reaction forms calcium acetate, water, and carbon dioxide gas.
What gas is given off in hydrochloric acid?
Hydrochloric acid gives off hydrogen gas when it reacts with certain metals, such as magnesium or zinc. When hydrochloric acid reacts with limestone (calcium carbonate), carbon dioxide gas is produced.
What gas is produced when calcium carbonate reacts with acid?
Carbon dioxide gas is produced when calcium carbonate reacts with acid. This is a common reaction that can be observed when a calcium carbonate-containing substance like limestone or chalk is exposed to an acid such as hydrochloric acid.
What is the name of the gas that is produced when a metal reacts with acid?
A salt. The type of salt depends on the type of acid.
Which gas is produced when an acid reacts with metal?
Hydrogen gas is produced when an acid reacts with a metal. This is because the acid reacts with the metal to form a salt and hydrogen gas.
What gas is produced when acid rain falls on a limestone statue?
When acid rain falls on a limestone statue, carbon dioxide gas is produced as a result of the reaction between the acid rain (which contains sulfuric acid or nitric acid) and the calcium carbonate in the limestone.
What gas produced when acid rain reacts with building stone?
When acid rain reacts with building stone composed of calcium carbonate (limestone), carbon dioxide gas is produced. This reaction forms soluble calcium ions that leach out, leading to the erosion and degradation of the stone structure over time.
When citric acid reacts with baking soda a salt water and a gas are produced. What is the name of the gas?
The gas produced when citric acid reacts with baking soda is carbon dioxide.
What gas is produced when metal reacts to acid?
When metal reacts with acid, hydrogen gas is produced. This is due to the displacement reaction where the metal displaces hydrogen from the acid to form hydrogen gas and a metal salt.
What gas is produced when metal reacts with dilute acid?
hydrogen gas
Why does limestone bubbles when acid is added to its surface?
Limestone contains calcium carbonate, which reacts with acid (such as hydrochloric acid) to form carbon dioxide gas. The release of carbon dioxide gas creates bubbles or fizzing on the limestone surface.
What happens when acid reacts with limestone?
When acid reacts with limestone, a chemical reaction occurs where the acid dissolves the calcium carbonate in the limestone, forming water, carbon dioxide, and a calcium salt. This reaction is known as neutralization and can result in the limestone dissolving or fizzing as the carbon dioxide gas is released.
