Answer : At temperatures greater than this reaction is spontaneous under standard conditions.
Explanation : Given,
= 131.3 KJ/mole = 131300 J/mole
= 127.6 J/mole.K
Gibbs–Helmholtz equation is :
As per question the reaction is spontaneous that means the value of is negative or we can say that the value of is less than zero.
The above expression will be:
Now put all the given values in this expression, we get :
Therefore, at temperatures greater than this reaction is spontaneous under standard conditions.

Answer:</h3>
- They show the elements of make up a compound
- They show the types of atoms that make up a molecule
- They show the number of each type of atom in a molecule
<h3>
Explanation:</h3>
To answer this question we need to know what is a compound.
- A compound is a substance that is made by two or more atoms of different elements that are chemically combined.
- A chemical formula of a compound is a formula that shows the elements that make up a compound and also the types of atoms that make up the molecule.
- Additionally, the chemical formula shows the number of each type of atom in a molecule.
- In this case, the chemical formula of a molecule of H₂O shows that it is made up of one hydrogen atom and two oxygen atoms.
Because they are closer to the farther end of the periodic table. Since they are closer to the farther end they don't want to give away their electrons because it would be easier for them to just steal them from other atoms.
The concentration of the sodium hydroxide will be 0.016 M
<h3>Stoichiometric problem</h3>
First, the concentration of the diluted nitric acid needs to be found.
m1 = 2.0 M, v1 = 100 mL, v2 = 300.0 mL
m2 = 2 x 100/300 = 0.6667 M
The equation of the reaction goes thus:
The mole ratio is 1:1.
Mole of 0.6667 M, 7.05 mL HNO3 = 0.6667 x 0.00705 = 0.0047 mol
Equivalent mole of NaOH = 0.0047 mol
Molarity of 0.0047 mol, 30.0 mL NaOH = 0.0047/0.3 = 0.016 M
