Answer: The correct answer is A. 11.5 atm. The temperature is held constant at 293 K, therefore, we can use Boyle's Law to determine the initial pressure. Boyle's Law states that there is an inverse relationship between pressure and volume of gases. Therefore, as volume increases, the pressure will decrease and vice versa.
Further Explanation:
Boyle's Law can be mathematically expressed as:
In this problem, we are given the values:
P(initial) = ?
V(initial) = 80 L
P (final) = 0.46 atm
V (final) = 2000 L
Plugging in these values into the equation:
The initial pressure was 11.5 atm. Since the volume increased or expanded, the space where the gas particles move is bigger, so the frequency of collisions with the wall of the container and with other particles are effectively decreased. This, therefore, decreases the pressure from 11.5 to 0.46 atm.

Water molecules combines of two hydrogen atoms and an oxygen atom
Answer:
Explanation:
mass of copper = 200 g at temperature 100°C
mass of water = 1000 g at 20⁰C
Let the final temperature be T .
specific heat of copper = .385 J per gram
specific heat of water = 4.182 J per gram
heat lost = mass x specific heat x fall of temperature
heat lost by copper
= 200 x .385 x ( 100 - T )
heat gained by water
= 1000 x 4.182 x ( T - 20 )
heat lost by copper = heat gained by water
200 x .385 x ( 100 - T ) = 1000 x 4.182 x ( T - 20 )
7700 - 77 T = 4182 T - 83640
4259 T = 91340
T = 21.44⁰C .
TPGS-750 M conducts reaction under lower temperature then the reactions carried out in organic solvents.
<h3>What is tpgs-750m ?</h3>
It is a chemical molecule of the second generation known as an amphiphile, with both hydrophilic and lipophilic qualities.
- In contrast to any other organic solvent, water is used for transition metal catalysed cross-coupling, making TPGS-750M a second generation surfactant with physical features that encourage this process.
- The hydrophilic portion of TPGS-750M, which is utilised in medicine, is made of Poly(ethylene glycol), and the hydrophobic portion is made of the vitamin E compound alpha-tocopherol.
