Bullcoin mining
secure payment. Qwc has no pre excavation and ICO, and adopts cryptonight algorithm (supporting mainstream mining machine X3 and A8 +) POW mining.
the mining revenue of IPFs is not only affected by the capacity of hard disk, but also by the network, so no matter how efficient the machine is, if it is put in the wrong place, it has little effect.
Covalent bonds are formed by sharing electron pairs
van der Waals force includes dispersion force, orientation force and inction force, which are related to molecular dipole
The van der Waals force between the particles should be the dispersive force The orientation force is the positive and negative attraction between the fixed dipoles of two polar molecules, and the inced force is the force proced by the fixed dipoles of a polar molecule incing a non-polar molecule to proce an instantaneous dipole The dispersion force is realized by the attraction of two instantaneous dipoles generated by the motion of the electrons between two nonpolar molecules. In molecular compounds, most intermolecular forces are realized by dispersive forces
extended data:
when polar molecules and nonpolar molecules are close to each other, under the influence of permanent dipole of polar molecules, the positive and negative charge centers of nonpolar molecules coincide with each other to proce inced dipole, resulting in electrostatic force between permanent dipole of polar molecules and inced dipole of nonpolar molecules, This force is called the incing force. When polar molecules are close to each other, under the influence of permanent dipoles, the distance between positive and negative charge centers of each polar molecule is enlarged, which will also proce inced dipoles, so the inced force also exists between polar molecules
