Answer:
D
Explanation:
Solar panels are not toxic, so option A goes out the window.
Aesthetics don't really matter, so option B follows it out.
Option C makes a little sense, but less so than Option D. They aren't nearly as heavy as some of our current energy production methods.
Solar panels are expensive, hard to store properly, and most are between 15 and 20 percent efficiency, compared with a diesel motor's 40 percent.
Matter and energy, and both these things are made up of atoms
Answer : The value of of the reaction is, -369.2 KJ
Explanation :
Formula used :
where,
= internal energy of the reaction = ?
= enthalpy of the reaction = -184.6 KJ/mole = -184600 J/mole
The balanced chemical reaction is,
when the moles of are 2 moles then the reaction will be,
From the given balanced chemical reaction we conclude that,
= change in the moles of the reaction = Moles of product - Moles of reactant = 4 - 4 = 0 mole
R = gas constant = 8.314 J/mole.K
T = temperature =
Now put all the given values in the above formula, we get:
Therefore, the value of of the reaction is, -369.2 KJ
Answer:
C
Explanation:
As C would be the wisest choice as being able to remember and use more words than the average human not only opens up your vocabulary but also your chances of writing a better essay using said words.
