This is the number of years Mrs. Shepherd has been teaching at OHS.
What is 2?
Two isotopes of the same element differ in what subatomic particle?

What happens to electrons in an ionic bond?
What is electrons are transferred?
What type of chemical reaction is demonstrated by A + B -> AB
What is synthesis?
What is the first step in most stoichiometry problems?
What is converting to moles?
“Heavier atoms always react faster.” Why is this incorrect?
What is reaction rate depends on many factors, not just mass?
What is CC, CWU, EWU, or WGU?
An atom has 17 protons and 18 electrons. What is its charge?
What is 1−?
Which group of elements is Beryllium most likely to react with?
What type of reaction is: AB + CD → AD + CB?
What is double replacement?
If 2 moles of H₂ react completely with O₂, how many moles of H₂O form?
What is 2 moles?
“All acids are dangerous.” Why is this false?
What is acids vary in strength; many are weak or safe (like vinegar)?
Mrs. Shepherd's favorite color.
What is pink?
Why do isotopes of the same element have nearly identical chemical properties?
What is because they have the same number of electrons and electron configuration?
What is the strongest type of intermolecular force?
What is hydrogen bonding?
Why is combustion always considered an oxidation reaction?
What is because oxygen is added and electrons are transferred from fuel to oxygen?

What is 66.7%?
“Electrons orbit the nucleus like planets orbit the Sun.” Why is this model outdated?
What is electrons exist in probability clouds (orbitals), not fixed paths?

A neutral atom has a mass number of 56 and 30 neutrons. How many electrons does it have, and what element is it?
What is 26 electrons; iron (Fe)?
Why does water have a relatively high boiling point compared to similar-sized molecules?
What is due to hydrogen bonding between molecules?
Balance the equation: __Fe2(SO4)3+__KOH→__Fe(OH)3+__K2SO4
What is : Fe2(SO4)3+6KOH→2Fe(OH)3+3K2SO4
Why does a limiting reactant determine the amount of product formed?
What is because it is completely consumed first, stopping the reaction?
A student says: “If I double concentration, reaction rate always doubles.” Why is this not always true?
What is reaction order determines relationship; it may be nonlinear?
This is Mrs. Shepherd's birthday.
