Answer:
2.3 atm
Explanation:
-7.50°C = 265.5 K
38°C = 315 K
(2.72)(265.5)=(pressure)(315)
pressure = 2.3 atm
Hydrogen peroxide mixed with vinegar makes peracetic acid, which is a toxic gas that irritates the skin and respiratory system

The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.
In order to calculate the final temperature of the gas, we may apply Charles's law, which states that the pressure and temperature of a fixed amount of gas at constant volume are directly proportional. Mathematically:
P/T = constant
(absolute temperature is used, so T = 672 + 273 = 945 K)
Thus,
3.9 / 945 = 12.2 / T
T = 2,956 K or 2,683 °C
