Answer: All the circuits have energy source, wires and device that needs electrical energy in common.
Explanation: Electric circuit is a path through which electrons flow from higher potential to lower potential.
A wire is required to connect Energy source and a device that needs electrical energy to run. On the other hand, voltmeter and ammeter are the devices which are used to measure voltage and current respectively and not necessarily used in all the circuits.
Hence, the common components in an electric circuit are energy source, wires and device that needs electrical energy in common.
Answer:
H = 0.800g
S = 12.8g
Explanation:
Each mole of H2S contains 2 moles of H and 1 mole of S
so .400 mole of H2S will contain .800 mole of H and .400 mole of S
Mass = mole x Mr
Mass H = .800(1) = .800g
Mass S = .400(32) = 12.8g
