How many grams of iron metal do you expect to be produced when 265 grams of an 84.5 percent by mass iron (ii) nitrate solution reacts with excess aluminum metal? show all of the work needed to solve this problem.
2 al (s) + 3 fe(no3)2 (aq) 3 fe (s) + 2 al(no3)3 (aq)

he would use the colour black

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

the awnser is group 12

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
