Describe the relationship between speed and kinetic energy. A) A positive linear relationship
B) A negative linear relationship
C) A negative but not linear relationship
D) A positive but not linear relationship

D) A positive but not linear relationship

Explanation:

This comes from the equation Ek=1/2mv^2

Where Ek is Kinetic Energy, m is mass, and v is the speed (or velocity).

As we can see in the equation, the relation is not linear but quadratic and it is positive.

"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"

a electronegativity decreases beacuse the size of nucleus is bigger.
