B. Energy transfer would occur between the copper bars and the surroundings.
Explanation:
In an open system, energy transfer would occur between the copper bars and the surroundings.
There are three types of systems:
- Isolated system in which matter and energy is not exchange with the surrounding.
- Closed system there is no exchange of matter but energy is exchanged with the surrounding.
- Open system: there is exchange of both matter and energy.
If the copper bars were placed in an open system matter and energy will be exchanged with the surrounding.

Answer: heyyyooo
The bond polarity for each bond in a BH3 molecule is polar, due to the difference in electronegativities of the B and H atom. The molecular shape is trigonal planar, and the molecule is non-polar - because due to the symmetry of the molecule, the polarities cancel out.

Answer:
The answer to your question is: 0.25 l
Explanation:
Data
P1 = 1 atm
V1 = 0.5 l
P2 =2 atm
V2 = ?
T = constant
Formula
V1P1 = V2P2
Clear V2 from the formula
V2 = V1P1/P2
Substitution
V2 = (0.5)(1)/2 substitution
= 0.25 l result
