Answer:
THANKSSS YOU HAVE A GOOD DAY TOOOO
The best answer to the question would be (A) longer average life span.
Though there is a correlation between life span and education levels, where the higher your education, the higher your life span, other factors influence how long you life, most notably, of course your fitness levels, health, and diet. Thus, if you want to live longer, it is better to invest your time and effort into those three things instead of attending a postsecondary institution.
Dam building across naturally flowing rivers tend to decrease discharge of surplus water into sea, reduce nutrient concentration in estuaries and coastal waters, and diminish plankton blooms as well as fish landings.
The energy needed to break the bonds of 2 moles of O2 gas would be 968 jk/mol.
<h3>What is a chemical bond?</h3>
A bond is a term that refers to the attractive interaction between atoms and molecules.
The energy needed by moles to interact is measured in joules per mole and is represented as follows:
In the case of O2 moles, they require 494 jk/mol, therefore, if we need to separate 2 moles of O2, we need 968 jk/mol.

Answer:
x=4
Explanation:
1.5(4+x)−3=4.5(x−2)
Step 1: Simplify both sides of the equation.
1.5(4+x)−3=4.5(x−2)
(1.5)(4)+(1.5)(x)+−3=(4.5)(x)+(4.5)(−2)(Distribute)
6+1.5x+−3=4.5x+−9
(1.5x)+(6+−3)=4.5x−9(Combine Like Terms)
1.5x+3=4.5x−9
1.5x+3=4.5x−9
Step 2: Subtract 4.5x from both sides.
1.5x+3−4.5x=4.5x−9−4.5x
−3x+3=−9
Step 3: Subtract 3 from both sides.
−3x+3−3=−9−3
−3x=−12
Step 4: Divide both sides by -3.
−3x−3=−12−3
x=4
