A 5.00 L sample of a gas at 25.0 °C is expanded under constant pressure to 12.5 L. What is the final temperature of the gas in °C?

Explanation:

According to the Ideal Gas Law for an isobaric process (at a constant pressure):  

(1)  

Where:  

is the initial volume of the sample

is the initial temperature of the sample in Kelvin

is the final volume of the sample

is the final temperature of the sample

So, we have to find from (1):

(2)

(3)

(4)

Transforming this result to Celsius:

This is the final temperature in Celsius.

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.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
