When dilute sulphuric acid is added to zinc granules the gas produced is?
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
Will there be a reaction between zinc and water?
Zinc reacts with steam to form Zinc oxide(yellow when hot and white when cold) and hydrogen. Zn+H2O=ZnO +H2
What is the effect on zinc granules when added to dilute sulphuric acid?
the test tube which holds the zinc becomes hot , the zinc turns into zinc chloride and hydrogen gas is produced. It is a chemical change.
When zinc reacts with hydrochloric acid will salt and hydrogen be produced?
yes
Name the salt that is produced when zinc reacts with dilute sulfuric acid?
Zn + H2SO4 --> ZnSO4 + H2Zinc + Sulfuric acid --> Zinc Sulfate + Hydrogen
Is zinc produced?
Yes, zinc is produced by extraction from ores.
When dilute sulphuric acid is added to zinc granules the gas produced is?
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
How was zinc first used?
The history of ZincCenturies before zinc was discovered in the metallic form, its ores were used for making brass and zinc compounds were used for healing wounds and sore eyes. Brass was produced by the Romans in the time of Augustus (20 B.C. - 14 A.D.). By 1374, zinc was recognized in India as a new metal and at Zawar, India, both zinc metal and zinc oxide were produced from the 12th to the 16th century. From India, zinc manufacture moved to China in the 17the century. Zinc was recognized as a separate metal in Europe in 1546. In 1743, the first European zinc smelter was established at Bristol in the United Kingdom.
Will there be a reaction between zinc and water?

Which out of carbon dioxide zinc chloride water and hydrogen is not produced from zinc carbonate and dilute hydrochloric?
This is hydrogen.
What does zinc plus hydrochloric acid react to give?
The products are zinc chloride and hydrogen.
When zinc is added to sulphuric acid what gas produced?
The gaseous product in this reaction is 'hydrogen' and the salt is zinc sulfate.
What is the effect on zinc granules when added to dilute sulphuric acid?
the test tube which holds the zinc becomes hot , the zinc turns into zinc chloride and hydrogen gas is produced. It is a chemical change.
What is the solid produced when zinc carbonate decomposes?
zn o2 ?
Which will melt first zinc or iron?
Zinc
What is made when you add zinc to sulfric acid?
Zn + H2SO4 --> ZnSO4 + H2 Zinc sulphate and hydrogen gas are produced.
When was zinc discovered?
Although zinc compounds have been used for at least 2,500 years in the production of brass, zinc wasn't recognized as a distinct element until much later. Metallic zinc was first produced in India sometime in the 1400s by heating the mineral calamine (ZnCO3) with wool. Zinc was rediscovered by Andreas Sigismund Marggraf in 1746 by heating calamine with charcoal. Today, most zinc is produced through the electrolysis of aqueous zinc sulfate (ZnSO4).
