Um try B? i think that would be correct. either B or C
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: It would be paint.
Explanation: it would be paint because it doesn't come completely together. another example of a heterogeneous mixture could be cereal and milk.
Answer: CaCO3 + 2HNO3 -> Ca(NO3)2 + H2O + CO2
Explanation:
Explanation:
Electron affinity is the energy released in adding an electron to a neutral atom in the gas phase. This is a measure of the readiness of an atom to gain an electron. When an atom gains an electron readily, it has a high electron affinity.
- The electronegativity is a property that combines the ability of its atom to lose and gain electrons.
- It is expressed as a number that describes the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.
Therefore , we see that an atom with a high electronegativity will have a very high affinity to gain electrons. It will want to attract electrons by all means to itself.
