In the laboratory, carbon dioxide is usually prepared by the action of dilute hydrochloric acid on marble chips.
To find the molarity, first calculate the number of moles of HNO3: 0.31g / 63g/mol (molar mass of HNO3) = 0.0049 mol Then, convert 300ml to liters: 300ml/1000 = 0.3 L Finally, molarity = moles/volume = 0.0049 mol / 0.3 L = 0.0163 M
XeO3 can be prepared by reacting xenon oxyfluoride (XeOF4) with water. XeOF4 can be prepared by the reaction of xenon with oxygen difluoride (OF2). Both reactions are carried out under controlled conditions in a laboratory setting.
The balanced equation for Na + HNO3 is: 2Na + 2HNO3 -> 2NaNO3 + H2
The molarity of the solution would be 0.1 M. This is because you need to calculate the number of moles of HNO3 first, which is 0.005 moles, and then divide by the volume of the solution in liters (0.3 L) to get 0.1 M.

lABORATORY METHOD:Nitric acid can be prepared in he laboratory by the action of the conc. h2so4 on the potassium nitrate
The chemical symbol for nitric acid is HNO3
Oxygen can be prepared by the electrolysis of water. 2H2O + electricity --> 2H2 + O2
The density of nitrogen prepared in the laboratory is less than that collected from air because laboratory-prepared nitrogen is often in a gaseous state, while nitrogen collected from air may contain impurities or be in a mixture with other gases which affects its density. Additionally, laboratory-prepared nitrogen may be at a higher temperature compared to ambient air, causing it to have a lower density.
Francium is a radioacive chemical element; francium is natural but also may be prepared in laboratory.
Many types of crystals can be prepared in laboratory or industry.
Nitric acid is a laboratory acid that contains nitrogen. It is a highly corrosive and reactive acid that is commonly used in various chemical reactions and industrial processes.
In the laboratory, carbon dioxide is usually prepared by the action of dilute hydrochloric acid on marble chips.
The first element prepared in a laboratory was phosphorus by the alchemist Hennig Brand in 1669. He extracted it from urine through a chemical process, marking the beginning of experimental chemistry.
The nitric acid is a strong inorganic acid, oxidizing agent, very corrosive but very useful in industry and laboratory; the chemical formula is HNO3.
We cant prepare it in lab. But there are aquas ammoni in lab.
