Answer:
It would be compound.
Explanation:
It is this way because if it adds another proton it becomes more positive that nuetral, and if you add an electron it just makes the atom more dense. That is why the answer is compound. Hope this helped :)
Answer:
it goes to a solid to a liquid
Explanation:
When something is a solid the molecules are impact together and have a small sense of vibration. But as the solid melts away for example ice, the molecules become more loose forming into a liquid
Answer:
To interpret a 13C-NMR spectrum we will use some standards very simple. A 13C-NMR spectrum gives us the following information:
1. Indicates the number of non-equivalent carbons in the molecule.
2. Measuring the chemical shift we can intuit the environment
electronic and determine the next functional groups.
3. In this case we cannot count on integration since the different
carbons have different relaxation times.
The number of peaks in the spectrum indicates the number of types of carbon present in the analyzed substance.
The factors that influence the chemical shift of the signals in the 13C NMR are:
- electronegativity of carbon bound groups
-
carbon hybridization
Explanation:
The nuclear magnetic resonance of C13 is complementary to that of H1. This technique is used to determine the magnetic environment of carbon atoms.
Answer:
Option b, The change in free energy of the reaction (ΔG)
Explanation:
Gibbs free energy is a measure of amount of usable energy in the system.
It is related with enthalpy (H), entropy (S) and temprature (T) as:
G = H - TS
The Gibbs free energy change (ΔG) provide spontaneity of a chemical reaction.
If ΔG is negative, then reaction is spontaneous that means reaction is moving towards forward direction.
If ΔG is positive, then reaction is non-spontaneous that means reaction is moving in backward direction.
If ΔG is zero, then reaction is at equilibrium.
Change in enthalpy only gives informtion about heat involed in a chemical reaction, it does not give information about direction of the reaction.
So, among the given options, option b is correct.
