What are the laboratory preparation of carbon dioxide?
In the laboratory, carbon dioxide is usually prepared by the action of dilute hydrochloric acid on marble chips.
What is the molarity of a solution prepared by dissolving 0.31g of HNO3 in 300ml of water?
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
How are XeO3 and XeOF4 prepared?
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.
Balance the following equation Na plus HNO3?
The balanced equation for Na + HNO3 is: 2Na + 2HNO3 -> 2NaNO3 + H2
What is the molarity of a solution dissolve 0.31 grams of HNO3 in 300ml of water?
Molarity = moles of solute/Liters of solution ( get moles of HNO3 and 300 ml = 0.300 Liters ) 0.31 grams Nitric acid (1 mole HNO3/63.018 grams) = 0.004919 moles HNO3 Molarity = 0.004919 moles HNO3/0.300 Liters = 0.0164 M HNO3

lABORATORY METHOD:Nitric acid can be prepared in he laboratory by the action of the conc. h2so4 on the potassium nitrate
What is nitric acids?
The chemical symbol for nitric acid is HNO3
How is oxygen gas prepared in the laboratory?
Oxygen can be prepared by the electrolysis of water. 2H2O + electricity --> 2H2 + O2
Why is the density of nitrogen prepared in the laboratory less than that collected in the air?
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.
Is francium synthetic and radioactive?
Francium is a radioacive chemical element; francium is natural but also may be prepared in laboratory.
Can you make crystal?
Many types of crystals can be prepared in laboratory or industry.
What is a laboratory acid that contains nitrogen?
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.

What is the first element prepared in laboratory?
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.
What is nitric?
The nitric acid is a strong inorganic acid, oxidizing agent, very corrosive but very useful in industry and laboratory; the chemical formula is HNO3.
