Con base en la siguiente reacción:

HNO3 + Sn + H2O > H2SnO3 + NO

a) Determina el estado de oxidación de todos los elementos presentes en la reacción.

b) Plantea las semirreacciones, ¿Cuál es el agente reductor y el agente oxidante?

c) Si se cuenta con una solución 1.5 M de ácido nítrico, 4 gramos de estaño y 2 gramos de

agua. Determina la cantidad de ácido estánico (H 2 SnO 3 ) que se genera.

d) ¿Cuál es el reactivo limitante?

Estoy perdido, la c y la d no tengo ni idea de por donde empezar. Si me pudieran ayudar se los agradeceria muchisimo.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

um i think it might be a car?

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