Acircuit contains two light bulbs connected in parallel. what would happen to the brightness of each light bulb if two more light bulbs were added in parallel to the first ones?

the brightness of each bulb would decrease because the total resistance of the circuit would decrease.

the brightness of each bulb would increase because the total resistance of the circuit would increase.

the brightness of each bulb would remain the same even though the total resistance of the circuit would decrease.

the brightness of each bulb would remain the

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?
