One kilogram of water (v = 1003 cm kg-1) in a piston/cylinder device at 25°c and 1 bar is compressed in a mechanically reversible, isothermal process to 1500 bar. determine q. w. au, ah, and as given that f = 250 x 10-6 k and x = 45 x 10-bar-. a satisfactory assumption is that is constant at its arithmetic average value.

answer; i do believe the correct answer is (river); /// good luck

no statements shown

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl

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
