How do you find the buoyant force of a balloon? Buoyant Force of Balloons The formula for buoyant force is: (B) = ρ V g. ρ = Density of Fluid (We used density of the air because the balloons were afloat, not submerged) V = Displaced Volume. g = 9.8 (gravity) Density of air(ρ)= 1.225 […]

What is produced when aluminum reacts with hydrochloric acid?
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 […]
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 […]
Who is often called the father of modern aviation?
Who is often called the father of modern aviation? Cayley was an aeronautical engineering pioneer and is often referred to as “the father of aviation.” He discovered and defined the four forces acting on a heavier-than-air flying vehicle: weight, lift, drag and thrust. Can planes fly without a tail? Can an airplane fly without a […]

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 […]
