1. iron forms a series of compounds of the type fe (co)y. if you heat any of these
compounds in air, they decompose to fe2o3 and co2 gas. after heating a 0.166 g sample
of fex(co)y, you isolate the co2 in a 2.50 l flask at 27.00 °c. the pressure of the gas is
33.42 mm hg. what is the formula of fex( show all calculations.

the dependant variable is spilled water

the independent is the heat

answer; capital earns interest; entrepreneurship receives a profit or incurs a loss;

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
