For the reaction below, the instantaneous reaction rate of O2 consumption is measured at 2.4 × 10−3 mol/L•s. What is the rate of production of CO2 at the time of the measurement? CH4(g) + 2O2(g) → CO2 + 2H2O (g)
(a) 2.4 × 10−2 mol/L•s (c) 2.4 × 10−3 mol/L•s
(b) 1.2 × 10−3 mol/L•s (d) 4.8 × 10−3 mol/L•s

City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8â° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was â’3â° c. what was the temperature of city a and city b on that day? city a was 5â° c, and city b was 4â° c. city a was 3â° c, and city b was â’1â° c. city a was 8â° c, and city b was â’3â° c. city a was 5â° c, and city b was â’5â° c.
