What else can I help you with?
What happened when you mix a solution of hydrogen peroxide and saturated potassium iodide with washing up liquid?
When a solution of hydrogen peroxide and saturated potassium iodide is mixed with washing up liquid, it produces oxygen gas rapidly due to the reaction between hydrogen peroxide and potassium iodide as a catalyst. The washing up liquid helps to trap the oxygen gas in the form of bubbles, creating a foamy reaction.
Does hydrogen have a texture?
Hydrogen is a gas and thus does not have texture .
Why is KBr liquid at room temperature?
KBr (potassium bromide) is a salt that has a relatively low melting point of 734 degrees Celsius. At room temperature and pressure, it remains in a solid state. To become a liquid, KBr must be heated above its melting point to transform into a liquid form.
What is colder helium or hydrogen?
Liquid Helium is colder than Liquid Hydrogen.
What is the state of hydrogen at room temperature?
At room temperature, hydrogen is a colorless, odorless gas. It is the lightest and most abundant element in the universe. Hydrogen becomes a liquid at very low temperatures, below -252.87 degrees Celsius.
What is the temperature of liquid hydrogen?
The temperature of liquid hydrogen is around -252.87 degrees Celsius or -423.17 degrees Fahrenheit.
Is hydrogen a liquid or gas at room temperature?

What hydrogen is a liquid below what temperature?
Hydrogen is a liquid btween -252,879 oC and 259,16 oC.
Is hydrogen a liquid at room temprature?
Hydrogen is not a liquid at room temperature. H2 changes from gas to liquid state at about -253oC .
What is hydrogen gas solid liquid?

What Chinese medicine called liquid brown mixture with opium has glycyrrhiza fluid extract antimony potassium tartrate ethyl nitrite spirit?
This liquid brown mixture is known as "Laudanum" in Chinese medicine. It contains opium along with ingredients such as glycyrrhiza fluid extract, antimony potassium tartrate, ethyl nitrite, and spirit. Laudanum has been historically used as a pain reliever and sedative but is highly addictive and has significant potential for abuse.
What is the state of matter for hydrogen peroxide?
Hydrogen peroxide is a liquid at room temperature, so its state of matter is liquid.
Is hydrogen bromide a solid liquid or a gas at room temperature?
Hydrogen bromide (HBr) is a gas at room temperature.
Is hydrogen sulphide a liquid?
Hydrogen sulphide (H2S) is a gas at room temperature.
What is an example of potassium as a liquid?
The melting point of potassium is 63.5 degrees C so it is liquid above that temperature. However potassium is so reactive that it will not survive unless air and water are excluded.
