If there is more than one path in a closed circuit for current to flow through: A. positive charge will flow in one branch, negative charge in the
other.
B. charge will accumulate in one path.
c. it is a parallel circuit.
D. no charge will flow.

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

Classify this reaction: 2al+n2-> aln.
