Refer to the following balanced equation in which ammonia reacts with nitrogen monoxide to produce nitrogen and water.
4NH3(g) + 6NO(g) → 5N2(g) + 6H2O(1)
How many moles of NO are required to completely react with 2.45
mol NH3?
mol NO

201cm/s÷5: 18

explanation:

there is no explanation

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
