DownloadWhat is the electron configuration of a neutral chlorine atom?
Omdraaien
The electron configuration of a neutral chlorine atom is 1s² 2s² 2p⁶ 3s² 3p⁵.
How many moles of oxygen gas are needed to completely react with 4 moles of hydrogen gas to form water?
Omdraaien
2 moles of oxygen gas are needed to completely react with 4 moles of hydrogen gas to form water.
Define the term isotope.
Omdraaien
An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in the nucleus, resulting in a different atomic mass.
What is the principle behind the Aufbau principle in electron configuration?
Omdraaien
The Aufbau principle states that electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
What is the molecular geometry of a water molecule?
Omdraaien
The molecular geometry of a water molecule is bent or V-shaped.
Explain the concept of electronegativity.
Omdraaien
Electronegativity is the measure of an atoms ability to attract and hold onto electrons within a chemical bond.
What is the standard enthalpy change of formation for an element in its standard state?
Omdraaien
The standard enthalpy change of formation for an element in its standard state is zero.
Describe what a catalyst does in a chemical reaction.
Omdraaien
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to proceed without being consumed in the process.
