Answer:
The energy should be high.
Explanation:
Bonds do store energy and release it depending if it's endothermic or exothermic. The energy should be low because when a bond forms (endothermic) it releases heat, which helps form bonds. Having a high energy means the bond is absorbing energy, which helps break bonds (endothermic). How this helps!
soluble substances dissolves in solvents
Answer:
3.75 atm
Explanation:
Volume remains constant, so we can use <em>Gay-Lussac’s Law</em>.
<em>p</em>₁/<em>T</em>₁ = <em>p</em>₂/<em>T</em>₂ Multiply both sides by <em>T</em>₁
<em>p</em>₁ = <em>p</em>₂ × <em>T</em>₁/<em>T</em>₂
<em>p</em>₁ = ?; <em>T</em>₁ = 299 K
<em>p</em>₂ = 7.77 atm; <em>T</em>₂ = 620 K Insert the values
<em>p</em>₁ = 7.77 × 299/620 Do the operations
<em>p</em>₁ = 3.75 atm
A general exponential expression is something like:
A^n
This means that we need to multiply the number A by itself n times.
Using that we will get (-2)^6 = 64
With that definition, we can rewrite:
(-2)^6 = (-2)*(-2)*(-2)*(-2)*(-2)*(-2)
So we just need to solve the above expression.
Also, remember the rule of signs:
(-)*(-) = (+)
We will get:
(-2)*(-2)*(-2)*(-2)*(-2)*(-2) = [(-2)*(-2)]*[(-2)*(-2)]*[(-2)*(-2)]
= 4*4*4 = 16*4 = 64
Then we got:
(-2)^6 = 64

Usually, a model is a depiction of a certain entity, never the real thing. In times
past, many, many models look great on paper but are way off!
