Arrange: Click Next element to select carbon. Add a second electron to the first 2p orbital. (not the second or the third 2p orbital)
Click Check. What feedback is given?
Electrons are properly arranged in shells.
Electrons not properly arranged in consecutive shells.
Electrons are properly arranged in energy levels.
O, Electrons not properly arranged in energy levels.

explanation:

i did this but i forgot how to do it

the dependant variable is spilled water

the independent is the heat

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.
