What is produced when aluminum reacts with hydrochloric acid? Aluminum metal reacts with hydrochloric acid to form hydrogen gas and an aluminum chloride solution. In this investigation, you will predict the mass of hydrogen gas produced by a given amount of reactants, then measure the amount, and compare them. Hydrochloric acid is an aqueous solution […]
What acetone Cannot dissolve?
What acetone Cannot dissolve? Many kinds of plastic do not dissolve in acetone. Polypropylene and nylon are unaffected, PTFE unsurprisingly handles it just fine as well. Two kinds of plastic that do dissolve in acetone are PVC and polystyrene. Why is nail polish soluble in acetone but not in water? Nail varnish does not dissolve […]
What are chemical properties of steel?
What are chemical properties of steel? Alloy Steel Alloy steels (like carbon steels) contain both carbon and iron, but add additional elements such as silicon, nickel, chromium, manganese, or vanadium. The extra elements added are what provide the additional features and varied chemical properties compared to carbon steels. Is gold a metal? Gold (Au), chemical […]
Why hydrogen ion does not exist?
Why hydrogen ion does not exist? Because the bare nucleus can readily combine with other particles (electrons, atoms, and molecules), the isolated hydrogen ion can exist only in a nearly particle-free space (high vacuum) and in the gaseous state. Why are H+ ions? Loss of an electron from H atom results in H+ . ion […]
What is the name of ch2?
What is the name of ch2? Methylene What functional group is ch2? methylene group What is och3 substituent called? methoxy-2-chlorobutanone. Is nitro electron-donating or withdrawing? Numerous studies on nitro group properties are associated with its high electron-withdrawing ability, by means of both resonance and inductive effect. Is MEO an electron withdrawing group? A methoxy group […]
Does light slow down in glass?
Does light slow down in glass? We all know that light bends when it travels through glass, water, or other transparent material. Electromagnetic waves simply travel slower through glass than through air. So the wave crests are closer to each other, but the light still oscillates the same number of times per second. It stays […]

What is the importance of rice and harm?
What is the importance of rice and harm? If you’ve ever hurt your ankle or had another type of sprain or strain, chances are your doctor recommended rest, ice, compression, and elevation (RICE) as one of your first treatments. The RICE method is a simple self-care technique that helps reduce swelling, ease pain, and speed […]
How can we help you or how may we help you?
How can we help you or how may we help you? The more polite expression is “How may I help you?” (“may,” not “many”). You will also hear people say “How can I help you?” To the punctilious, “may” is preferable to “can,” but both expressions are gracious and acceptable, much better than “Whassup?” How […]
Which biogeochemical cycles are key to life?
Which biogeochemical cycles are key to life? The nitrogen cycle is another biogeochemical cycle critical to life (Fig. 6.10). Nitrogen is especially important to ecosystem dynamics because many ecosystem processes, such as primary production and decomposition, are limited by the available supply of nitrogen. Which biogeochemical cycle is most important? carbon cycle Which cycle is […]
