Help? 4 me? ples? Balance these equations by writing the proper coefficients in the blanks provided.
NOTE: Not all blanks will receive numbers. If the equation is already balanced, indicate that you know this in the margin by writing “AB” (already balanced) after the problem number.
6. Sn + O2 --> SnO2
7. SnO2 + C --> Sn + CO2
8. C + CuO --> CO2 + Cu
9. CuO + C --> Cu + CO¬2
10. NO + O2 --> NO2

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

*will mark you brainliest + 15 points ** why does the equilibrium of a system shift when the pressure is increased? a. to maximize the stress on the system b. to stop restoring equilibrium to the system c. to increase the total moles of gas in the system d. to decrease the total moles of gas in the system

Apump contains 0.5 l of air at 203 kpa.you draw back on the piston of the pump, expanding the volume until the pressure reads 50.8 kpa. what is the new volume of the air pump
