Why can the charge of the nucleus never be +8​

it could destroy the nucleus

Explanation:

due too much power going into it

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
