WebInside the guts of a microwave, a device called a magnetron channels electrical energy from a power outlet to a heated filament, creating a flow of electrons that in turn transmits microwaves into the cooking chamber through an antenna. WebBoth molecules experience hydrogen bonding, and individually a hydrogen bond in hydrogen chloride is stronger than one in hydrogen sulfide. However hydrogen sulfide has more hydrogen atoms and can therefore make more hydrogen bonds per molecule compared to hydrogen chloride.
