A chemical reaction is occurring inside a beaker and the temperature of the beaker is monitored. What would the contents of the
beaker be referred to as? the system the surroundings the boundary the universe
1 answer:
<u>Answer:</u>
<em>The system is the Answer </em>
<em></em>
<u>Explanation:</u>
System is the region which is taken into consideration.
While we perform a chemical reaction the system is the substance taken in the container.
So, A thermodynamic system is the amount of matter or the region in universe which is under the study.
The region outside the beaker are called as surroundings.
The beaker (the surface which separates the system from its surroundings) is said to be the boundary
System + surroundings = universe

The distribution of electrons in an element's atomic orbitals is described by the element's electron configuration. Atomic electron configurations adhere to a standard nomenclature in which all atomic subshells that contain electrons are arranged in a sequence with the count of electrons they each hold expressed in superscript.
The atomic number Cr is 24. it has 24 electrons so the electronic configuration of
