Question 18 of 254.0/ 4.0 PointsA test balloon contains 500. mL of 298.15 °K gas. If I heat the gas in the balloon to 323.15 °K with a laser,what will be the new volume of the gas in L?A.0.193 LB.1.00 LC.0.461 LD.0.542 L
Feedback:
The volume is directly proportional to the absolute temperature (K) for a fixed amount of an ideal gas atconstant pressure.
Question 19 of 254.0/ 4.0 PointsThe air that we breathe is actually a mixture of several gases. Of those involved, which is themajorcomponent of the mixture?
individual component gases.Part 4 of 4 - Part 0520.0/ 24.0 PointsQuestion 20 of 254.0/ 4.0 PointsN2is non-reactive, however, if you can get it to react with H2, it does so in a 1:3 mole ratio (N2:H2) andreleases 92.0 kJ of thermal energy. That means which if these statements are true?
Question 21 of 254.0/ 4.0 Points
Magnesium oxidizes via the reaction:2 Mg + O2→ 2 MgOThe reaction has aHrxn= -1203 kJ. How much heat (in kJ) is released when you completely react 3.000moles of O2?
