El número de microorganismos presentes en el agua no afecta el proceso de desinfección. Quiere decir que para acabar una gran cantidad de estos se requiere la misma concentración y tiempo de contacto del desinfectante que para eliminar una cantidad pequeña, siempre y cuando la temperatura y pH del agua sean los mismos. - Fake
- True
Why?

PLEASE HELP I WILL GOVE BRAINLIEST

Which act would represent an example of “civil disobedience?

Explanation:

de contacto del desinfectante

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

50.23 i believe is correct but don't quote me on that.
