What does the average atomic mass represent
The average atomic mass represents the weighted average of the
masses of the isotopes of the element.
How do scientists design a system
They isolate their experiment from unwanted influences.
How is stoichiometry used to calculate the amount of product produced
Stoichiometry relates moles of reactant to moles of product, so
if you have the amount of reactant in the equation, you can
calculate the amount of product produced.
What best describes how forces affect matter
Forces hold matter together.
How do atoms show both unity and diversity
There are relatively few atoms, but they make many
molecules.
What happens to the anode in an electrochemical cell
What branch of chemistry studies the flow of electrons
Which electrode gets heavier in an electrolytic cell
The electrode where reduction occurs.
All life on earth is ultimately dependent on what
What would be the percent yield of the reaction be if the theoretical yield is 11.22 g but the actual yield was 8.67 g
In this case the yield is 77,27 %.
Which of the following statements describes electromagnetism
Magnetism can create electricity, and electricity can create
magnetism.
In the reaction mgcl2 plus 2koh mgoh2 mgoh2 plus 2kcl if 3 moles mgcl2 are added to 4 moles koh what determined how much mgoh2 is made
