This passage describes a chemical reaction. read the passage. then, answer the question below.

as the cells in your body break down food, a poisonous substance called ammonia (nh3) begins to build up in your blood. to reduce the amount of ammonia in your blood, your liver combines ammonia with carbon dioxide (co2) and other substances to make urea (ch4n2o). the urea later leaves your body as waste.

in the chemical reaction described in the passage, which of the following are reactants? select all that apply.

answers: carbon dioxide (co2), urea (ch4n2o), ammonia (nh3)

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
