Which question correctly describes how light is produced * electrons jump to higher energy level, and then fall back down again very quickly releasing energy

electrons start in the excited state and then lose energy after a long period of time

electrons absorb energy to go to the ground state and then release energy

electrons jump to a lower energy level and then fall to the excited state and release energy

How many rings would you draw in a Bohr Diagram for an atom with an atomic number of 56 and an electron configuration in the ground state

five rings because that atom has five electrons

six rings because that atom has six energy levels

four rings because that atom has four valence electrons

six rings because that atom had two valence electrons jump to a higher energy level.

Both 2 and 4

atom

Explanation:

it would be  an atom because they would jump higher then any of the electrons.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
