A team of engineers is working together to design a new airplane. The team members each live in different cities. For which purpose is the Internet most useful to the team?
at least two complete sentences.

The internet is useful to this team because then they can keep in contact with eachother, as well as know what the weather will be like in their cities (weather monitoring). This way they can see which flights are closed down in their airportm and if any of those flights would've went to their airport (Mitigating Flight Delays). So the two reasons the internet would be useful is for weather monitoring and mitiagating flight delays, for example, one million flight delays equals 64 million minutes in added wait time for passengers, so it's best to know ahead of time to give passengers alternatives.

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
