shown in the table.
Molar Mass
Comparison
Gas Molar Mass
A 4.00 g/mol
B 2.01 g/mol
Which statement describes the density and effusion of both gases at STP? (4 points)

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

it's c (engineer's do their work with mechanical stuff not on any living being)
