Answer: 8.45 L
Explanation:
Given that,
Initial volume (V1) = 3.5L
Initial pressure (P1) = 2.5 atm
[Since final pressure is given in torr, convert 2.5 atm to torr
If 1 atm = 760 torr
2.5 atm = 2.5 x 760 = 1900 torr
Final volume (V2) = ?
Final pressure (P2) = 787 torr
Since pressure and volume are given while temperature remains the same, apply the formula for Boyle's law
P1V1 = P2V2
3.5L x 1900 torr = 787 torr x V2
6650L•torr = 787 torr•V2
Divide both sides by 787 torr
6650L•torr/787 torr = 787 torr•V2/787 torr
8.45 L = V2
Thus, the volume of the gas at 787 torr and at the same temperature is 8.45 Liters
They have 2 oxygen atoms in 02
The word elliptical refers to regular ovals.
They rarely occur at molecular levels is incorrect, actually they always occur at molecular levels
Answer:
The term "three-dimensional learning" refers to the three pillars that support each standard, now called "performance expectations." These three dimensions are: Science and Engineering Practices, Crosscutting Concepts, and Disciplinary Core Ideas. You can use this rubric to evaluate your own curriculum for NGSS.
