3.00 L of CH4 is known to contain 0.650 moles at a certain temperature and pressure. if the volume of a chamber of CH4 increases from 7.00 L to 8.20 L how many moles of CH4 were added? Assume temperature and pressure stayed constant. moles

the answer is minerals.

girl imma just put my comment here because i need a couple point okurrttt

it's c (engineer's do their work with mechanical stuff not on any living being)

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
