Please i beg you, please help me and try your best. i'm getting graded for this and its easy and simple. thank you it means alot to me. A geyser shoots water and steam out of the ground. The hottest geysers heat steam to temperatures of 200°C or higher.

Volcanoes, geysers, and hot springs all provide clues about Earth's interior. They also show one of the ways that Earth's layers interact with each other.
1. What do you predict Earth's interior is like? How do its rocks compare to rocks on the surface? Cite evidence that supports your prediction.

just say you don't know and that you don't wanna find out because its hot

Explanation:

that's what i did and my teacher said i did good

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
