At 25 °c the solubility product constant, ksp, for mns in 5 x 10−15 and the acid dissociation constants k1 and k2 for h2s are 1 x 10−7 and 1 x 10−13, respectively. what is the equilibrium constant for the reaction represented by the equation above at 25 °c?

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

idk i’m struggling too

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

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.
