Sodium Chloride is a example of a ionic bond one atom is positively charged while the other is negatively charged both end up becoming neutral charge after they bond. check my answer to make sure that statement is accurate.
The correct answer would be the second option. When the gibbs free energy of a system is negative and the electromotive force (EMF) of the system is positive then the reaction is to occur readily without any input of energy. With this, the reaction is said to be spontaneous. The higher the value of the EMF of a cell then it means the driving force for the reaction to occur is also high.
the particles from solid to liquid start to move around faster then it was at the first state
Temperature,as the temperature and therefore, kinetic energy,of a gas changes the ,the RMS speed of the gas molecules also changes
