Answer: where’s the picture
Explanation:
Answer:
5.90 moles of ethane, C₂H₆, is burned in an excess of oxygen to produce 11.8 moles of CO₂.
Explanation:
To answer the question, we examine the chemical reaction as follows
2C₂H₆ ( g ) + 7O₂ ( g ) ⟶ 4CO₂ ( g ) + 6H₂O ( g )
From the chemical reaction it is seen that 2 moles of ethane, C₂H₆, is required to produce 4 moles of CO₂
This means that 1 mole of C₂H₆, is required to produce 2 moles of CO₂
Since we are asked to find out how many moles of CO 2 are produced when 5.90 moles of ethane is burned in an excess of oxygen and we already know that 1 mole of C₂H₆, is required to produce 2 moles of CO₂, we multiply both the 1 mole of C₂H₆ and the 2 moles of CO₂ by 5.90 to obtain;
(5.90 × 1 mole) of C₂H₆ is required to produce (5.90× 2 moles) of CO₂ or
5.90 moles of C₂H₆ is required to produce 11.8 moles of CO₂.
Answer:between 25 and 40 degrees Fahrenheit
Explanation:
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
Ways to increase reaction rate:
*increase the total surface area per volume ratio
*increase the temperature
*increase the pressure
*decrease the size of particles
