First, let's remember the concepts of spontaneous and nonspontaneous reaction:
A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. This would be called an exothermic reaction, it releases energy.
A nonspontaneous reaction is a reaction that does not favor the formation of products at the given set of conditions. In order for a reaction to be nonspontaneous, it must be endothermic, accompanied by a decrease in entropy, or both.
In this case, when the reaction takes place, the temperature of the system increases which means that heat is released and heat is a form of energy. Energy is released.
The answer based on this logic would be D.
The answer is 1.26 Mol
n = PV/RT= (1.2 atm)(31 L) / (0.0821 )(360K) = 1.26 mol H2
Correct Answer: Option C
Reason:
<span>The </span>Pauli Exclusion Principle<span> states as '<em>in an atom or molecule, no two electrons can have the same four electronic quantum numbers. Further, an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.</em>'
</span>
Thus, it can be seen that in option C, electrons in last 2 subshell have electrons with same spin, which is a violation of Pauli Exclusion Principle .
Answer:
Glucose = C6H12O6
molecular mass = 6(12) + 12(1) + 6(16)
= 72 + 12 + 96
= 180 g
Explanation:
Glucose has a chemical formula of: C6H12O6 That means glucose is made of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. ... Glucose is produced during photosynthesis and acts as the fuel for many organisms.
