If two gases with pressures of 2 atm and 3 atm are mixed at constant temperature, the total pressure will be the sum of the two pressures. Therefore the answer is D. 2 atm + 3 atm or 5 atm will be the total pressure of the gas mixture.
Explanation:
2KCLO3 (s) = 2KCl (s) + 3O2 (g)
Answer:
Heat flows from the lower-temperaturesubstance to the higher-temperaturesubstance. Heat does not flowbecause both substances are at the same temperature. ... Heat is the energy that flows between twosubstances of different temperatures.Heat is the energy that flows between two substances of different temperatures.
To calculate the average atomic mass, Multiply the fraction by the mass number for each isotope, then add them together. Hope this helps. :)
Answer:
It will take 19.044 sec for 0.15 mol of Cl2 to effuse under the same conditions
Explanation:
From Graham's law of effusion, R1/R2 = √(M2/M1)
Since the number of moles is the same,
t2/t1 = √((M2/M1)
t1 (time taken for I2 to effuse) = 36 sec, M2 (molecular weight of Cl2)= 2×35.5 = 71, M1 (Molecular weight of I2) = 2×126.9 = 253.8
t2/36 = √(71/253.8)
t2/36 = 0.529
t2 = 36 × 0.529 = 19.044 sec
