Most lakes have rivers flowing out of them, carrying water to the ocean. However, some lakes, including Great Salt Lake and the Dead Sea, have no outlet. Water flowing into these lakes leaves only through evaporation. Considering that the water flowing into the lakes contains many dissolved substances, how does the lack of an outlet affect the composition of these lakes? What would you expect to happen after many more years of inflow and evaporation? please right out an explained answer

sure im new too!

explanation:

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
