Methane (ch4), ammonia (nh3), and oxygen (o2) can react to form hydrogen cyanide (hcn) and water according to this equation: ch4 + nh3 + o2  hcn + h2o you have 10 g of methane and 12 g of ammonia in excess oxygen. answer the following questions: what is the balanced equation for this reaction? which reagent is limiting? explain why. how many grams of hydrogen cyanide will be formed? show your work.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
