Answer:
<h2>
2Al +
3CuO ==>
3Cu + Al2O3</h2>
Explanation:
So let's break this chemical equation down into 2 parts - Reactants and Products
Reactants = Al + CuO
Products = Cu + Al2O3
So the Chemical Reaction will be
Al + CuO ==> Cu + Al2O3
So the balanced equation will be,
2Al + 3CuO ==> 3Cu + Al2O3

Answer:
Any nucleus that has an overall spin quantum number of zero (I=0) is NMR inactive
Explanation:
A wide range of nuclei are found to be NMR active. NMR is the acronym for nuclear magnetic resonance. It is a powerful spectroscopic tool which uses radio waves. The nuclear spin is described by the nuclear quantum number I and can take on values of; 0,1/2, 1, 3/2,2,5/2 etc.
Any nucleus that has an overall spin quantum number of zero (I=0) is NMR inactive e.g Carbon-12 and Oxygen-16 nuclei.
Commonly, all NMR active nuclei posses I ≥ 1/2, Hydrogen -1 , Carbon-13 and boron-11 are common examples of NMR active nuclei.
Answer:

Answer:
(a) 16500 grams
(b) 16500000 milligrams
(c) 16500000000 micrograms
This is just addition. Put 2140.56 on top, line up 9.3456 under it appropriately. Doing this will give you the answer: 2149.9056
