There are three reactions in the iodine clock reaction. The first reaction is IO3-(aq) + 3 HSO3-3 SO4-(aq) + I-(aq)+ 3 H+(aq)‚ where the iodate ions become iodide ions1. The second reaction is 6 H+(aq) +IO3-(aq) + 5 I-(aq) 3 I2(aq) + 3 H2O(l) where the iodate ions become molecular iodine2. The third reaction involves molecular iodine becoming a dark blue starch;I2(aq) + starch blue-black complex3. These three reactions react in a sequence. In any reaction the concentration is exponentially related

of a propeller but not sufficient information for the detailed design. Detailed information can be obtained through analysis of the forces acting on a blade element like it is a wing section. The forces acting on a small section of the blade are determined and then integrated over the propeller radius in order to predict the thrust‚ torque and power characteristics of the propeller.

Some countries in the world use a 24 hour clock. In other words‚ instead of saying 3 a.m. and 3 p.m. to distinguish between morning and afternoon times‚ they say 0300 and 1500. In many countries‚ this is the standard and is called the 24 hour clock. In a few countries‚ like the U.S.‚ a 12 hour clock is the standard default for the general population‚ but certain sub-populations‚ such as the military‚ use the 24 hour clock. In those countries‚ this is often referred to as military time. For the

What Are Aircraft? Everyone has seen a jet streaking across the sky leaving a trail of vapor as it goes. Maybe you have heard the distinct thud‚ thud‚ thud as a helicopter slows in its descent. You have probably marveled at a plane so massive that it seems to just hang in the air by some invisible force. These wonderful marvels of human engineering have captured the hearts of many. They are known the world over as aircraft. But what is an aircraft? Aircraft’s are comprised of many different things

HOW TO BUILD A MULTICOPTER (DIY):- If you build lite and keep the aircraft lite it will fly like a dream. Usually people use payloads:- Cameras:- a GoPro HeroHD2 or HD3 ‚ a Panasonic GH2/GH3 or Nex5/Nex7 or a NikonV1/J1 camera. SLR cameras can be flown but their large heavy mirror designs are irrelavant in the air when the pilot is actually on the ground not using the mirror box. The new generation of mirrorless cameras such as the GH2/GH3 and Nex5/Nex7 which produce Pro quality video as minimal
