@prof_vicki_w #ChemsGr8 #SolutionSquad Multiple resonance structures in the Lewis dot structure system can represent the same molecule and, when put together, represent the full structure of that molecule.

@prof_vicki_w #Solutionsquad #ChemsGr8 A limiting reagent is a reactant in a chemical formula that limits the amount of product that can be made due to there not being enough of it.

@prof_vicki_w #SolutionSquad #ChemsGr8 The subscripts represent the amount of each element there is that is present in the substance while the coefficient tells you how many molecules there are of that substance.

@prof_vicki_w #SolutionSquad #ChemsGr8 When an atom does not have a full outer shell, it may pair up with other another atom, pairing their electrons together to form a covalent bond so that both atoms can have a full outer shell with 8 valence electrons.

@prof_vicki_w Accuracy is how close the objects are to the intended target, such as darts on a dartboard. Accuracy would be how close the darts are to the middle. Precision is how close the darts are to each other.

@prof_vicki_w I wake up every day and make a cup of coffee! The coffee beans themselves are roasted, causing a chemical change in the beans. When I buy them, they are already ground up which, along with brewing my cup of coffee, is a physical change.
