Candi uses wires to connect a battery to a light bulb. She knows she has made a complete circuit because the light bulb lights up. Candi's teacher gives her a wire that has a lot more resistance than the wires she used at first. Candi removes one of the original wires from her circuit and puts the high-resistance wire in its place. What effect will this most likely have on the circuit?
A.
Less current will flow, so the light bulb will be dimmer.
B.
More current will flow, so the light bulb will be brighter.
C.
The battery will have more voltage, so the light bulb will be brighter.
D.
The battery will have less voltage, so the light bulb will be dimmer.

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.
