How does evaporation lead to precipitation

1.evaperation

2.condenstation

3.precipatation

Explanation:

So I guess condenstation leads to precipatation-

Evaporation is when water/liquids changes state from a liquid to a gas. Which eventually with enough water water vapor (which is what forms when water evaporates), it turns into clouds. But when the clouds get too heavy and full of water. Rain/precipitation falls from those clouds.

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
