Hen 20 g of Al (s) at 98 degrees Celsius is placed in 50 g of H2O , the final temperature is 26.5 degrees Celcius. What was the initial temperature of H2O ? Given: CspAl(s) = 0.903 J/g C and CspH20(l) = 4.18 J/g C

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants

wher is the rest of the question

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

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.
