Answer:
3 Mg + Fe2O3 = 3 MgO + 2 Fe
The reaction type is single replacement
Explanation:
The number of Valence electrons are the same number as the group the element is in. For example Carbon is in group 4 and has 4 Valence electrons.
Answer:
See explanation
Explanation:
Accidental overlap of signals are common in H-1 NMR than in C-13 NMR for the following reasons;
1) 13C has a very low natural abundance compared to H-1
2) 13C nucleus is s many times lesser in NMR sensitivity than H-1 nucleus.
3) As a result of its low abundance, 13C-13C coupling is not common.
4) Longer relaxation times do not give room for integrations.
5) Peaks in 13C spectra mainly consists of single lines.
As a result of all these, 13C-NMR spectra take longer to acquire than H-NMR. Hence, accidental overlap of signals is much more common in H-1 NMR than in C-13 NMR.
The ph 11 milk because on the ph scale(0-14) a 7 is neutral anything under a 7 is a acid anything above a 7 is a base
