If 13 grams of CH 20. are reacted with 25 grams of Oy, what is the limiting reactant if the goal is to make water? What mass of water is produced by the
limiting reactant?

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
