What are analog and digital information? how are they similar? how are they different? give at least two common examples of each. how are analog and digital information transmitted? what kind of information does each transmit best? which type easily loses part of its signal to noise, and which does not? how are analog and digital information stored? what kinds of benefits and drawbacks come from each storage method? discuss stability and security. i will give brainliest!

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
