Technician A says that an oxygen sensor can have one, two, three, four, or more wires, depending on the style and design. Tec
1 answer:
Answer:
Both technicians A and B are right.
Explanation:
-The most common application is to measure the exhaust-gas concentration of oxygen.The probe typically has four wires attached to it: two for the lambda output, and two. The number of wires depends on design and style.
-An oxygen sensor will typically generate up to about 0.9 volts() when the fuel mixture is rich and there is little unburned oxygen in the exhaust. When the mixture is lean, the sensor's output voltage will drop down to about 0.1(
)volts

The amount of heat required for the sublimation of 40.0 g of solid dry ice CO₂ is <u>29.3 kJ.</u>
One mole of CO₂ has a mass of 44.0095 g.
Calculate the number of moles n in 40.0 g of CO₂ .
Heat of sublimation is the amount of heat required by 1 mole of a substance to convert itself from solid state to a vapor state at constant temperature and pressure.
1 mole of CO₂ requires 32.3 kJ of energy to sublimate.
Therefore, the heat required to sublimate 0.9089 mol of CO₂ is given by,
Thus, the heat required to sublimate 40.0 g of CO₂ is <u>29.3 kJ</u>.
