At ST P, according to Ideal GasLaw, ALL gas (element, mixture, etc) are 22.4L per mole. Mole is 6.02 r 10^23 particlesof a particular matter. Molar mass is calculated by adding the mass number of each element. So for the first question, since 22.4L is one mole of nitrous oxide ...
In the chemical reactor there's a vacuum very close to that of interstellar space. And the temperature is minus 200° Celsius.在化学反应堆中有一个非常接近星际空间的真空空间。温度是- 200摄氏度。We made the ice, we can see a bit here, a sort of growth on the edge of the window. The ...
What is the pressure of the gas in the mercury manometer if h = 55 mm and atmospheric pressure is 760 mmHg? A. 815 mmHg B. 760 mmHg C. 55 mmHg Manometer: In fluid mechanics, manometers are the devices used to measure...
but sometimes, you have to consider what you're cleaning also. Although household bleach is mostly water, it can still be irritating on its own because of the strong smell. The sodium hypochlorite that is the main ingredient in bleach reacts when it is mixed with either ammonia-based cleaner...
A 0.029 m^3 tank contains 0.072 kg of Nitrogen gas (N2) at a pressure of 3.67 atm. Find the temperature of the gas in Celsius. Take the atomic weight of nitrogen to be N2 = 28 g/mol. If 37.5 mol of an ideal gas occupies 28.5 L at 437 K, what is the pressure of the gas?
This involves adjusting temperature, pressure, and flow controls so the system operates efficiently. Regular calibration aligns the system’s operation with its intended design, preventing inefficiencies from developing. When dealing with systems that use ammonia as a refrigerant, prioritize safety. ...
Also known as solid-state coolers, thermoelectric fridges use metals like copper or zinc and thermal energy — instead of liquid or gas refrigerants — to keep things cold. Electricity consumption is considerably higher than with compressor or ambient fridges. While you can operate one with a batt...
In chemistry,organic compoundsare generally anychemical compoundsthat containcarbon-hydrogen bonds. Almost all theplastic compoundsused today are organic, constituted of very big molecules made by long chains of carbon atoms. For instance,Polyethilene(PE) is anorganic polymerwith every carbon atom bon...
Examples of Heterogeneous catalysis: Oxidation of sulphur dioxide: Haber process: Ammonia into nitric acid: Homogeneous catalysis: When the catalyst and the reactions are both in the same phase (i.e. solid, liquid or gas). It is stated that the homogeneous catalyst. The reactions, products, an...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
