A sample of nitrogen gas collected at a pressure of 1.03 atm and a temperature of 279 K is found to occupy a volume of 568 milliliters. How many moles of N2 gas are in the sample

0.025 moles of nitrogen gas are there in the sample.

Explanation:

According to ideal gas equation:

P = pressure of gas = 1.03 atm

V = Volume of gas = 568 ml = 0.568 L   (1L=1000ml)

n = number of moles  = ?

R = gas constant =

T =temperature =

0.025 moles of nitrogen gas are there in the sample.

1. they vary with a higher number because boiling is way hotter than melting

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.
