Split screen multitasking. Apple is finally adding split screen multitasking support to iOS 9. With the latest update, users of iPad Air 2 will be able to run two apps side by side on their tablets, allowing you to do two things at the same time.While this has long been one of the core features of Samsungâs Galaxy smartphones, Apple is still restricting this to the iPad Air 2.ll of this points to a really good annual iOS update and it should fix a lot of issues people have had with iOS 8. This also helps Apple achieve some sort of feature parity with Android, silencing a lot of critiques at the same time. As of now, the iOS 9 update is scheduled to drop later this fall.
A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges, either between electrons and nuclei, or as the result of a dipole attraction. strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals.
Stable chemical bonds release energy as they form, and bond formation thermodynamically happens spontaneously. However, formation reactions often do require energy of activation to rearrange bonds and get reactions over activation barriers (which usually involves breaking bonds first before forming new ones).
