When 9.8 mol fe react with 11.5 mol hcl, what is the limiting reactant and how many moles of h2 can be formed?
unbalanced equation: fe + hcl yields fecl3 + h2
hcl is the limiting reactant, and 3.83 mol h2 can be formed
fe is the limiting reactant, and 4.90 mol h2 can be formed
hcl is the limiting reactant, and 5.75 mol h2 can be formed
fe is the limiting reactant, and 14.7 mol h2 can be formed

If we compare and contrast electromagnetic waves with sound waves, all but one statement is true. that is a) sound waves require a medium to travel while electromagnetic waves do not. b) electromagnetic waves can travel through the vacuum of space while sound waves cannot. c) electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere. eliminate d) sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.
