Based on your knowledge of energy resources conservation, which of the following statements is true? a) Manufacturers can increa
se a light bulb's energy efficiency by using technology that decreases the amount of electromagnetic energy the bulb converts from a given amount of electrical energy. b) Energy resources can be conserved by turning off lights when they are not in use. c) both a and b d) neither a nor b
When useful energy is conserved then this conservation is known as energy conservation.
For example, when lights of a room are switched on where no one is sitting then on switching off the lights we are conserving wastage of electricity.
Thus, we can conclude that out of the given options, the statement energy resources can be conserved by turning off lights when they are not in use is true.
Because there is only one stable ionic compound made up of potassium and chlorine, and that is KCl. So calling is "mono chloride" or similar would be redundant assuming you understand basic chemistry (i.e. knowing oxidation numbers of K is +1 and Cl is -1). When compounds can exist in multiple forms in nature like CO and CO2 you will preferably indicate it through the nomenclature, calling one a monoxide and the other a dioxide.
