German physicist werner heisenberg related the uncertainty of an object's position ( δ x ) (δx) to the uncertainty in its velocity ( δ v ) (δv) δ x ≥ h 4 π m δ v δx≥h4πmδv where h h is planck's constant and m m is the mass of the object. the mass of an electron is 9.11 × 10 − 31 kg. 9.11×10−31 kg. what is the uncertainty in the position of an electron moving at 6.00 × 10 6 m/s 6.00×106 m/s with an uncertainty of δ v = 0.01 × 10 6 m/s ?
nacl, molecules are ionic bonding this is covalent
hi my dear friend,
changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing. when steam, which is gaseous water, condenses, heat is released. likewise when liquid water freezes, heat is given off. in fact heat must be continually removed from the freezing water or the freezing process will stop.
