resistor 2, which is then connected back to the battery. What can be said
about this circuit?
O
A. Charge will build up between the resistors.
B. This is not a closed circuit
C. This circuit will not permit current flow.
D. This is a series circuit.

u i forgot the answer?

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.
