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 […]
Are hydrogen or electric cars better?
Are hydrogen or electric cars better? Hydrogen fuel cell vehicles tend to be more frugal than their battery electric counterparts. According to Autocar, the Hyundai Nexo comes with a real-world range of 414 miles and filling up takes just five minutes, whereas electric charging can be an hour-long affair at the best of times. Is […]
What is the difference between structural and ball and stick model?
What is the difference between structural and ball and stick model? A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. A structural formula indicates the bonding arrangement of the atoms in the molecule. Ball-and-stick and space-filling models show the geometric arrangement of atoms […]

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 […]
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 […]
