Disjoint means they have no elements in common. The union is the set of elements containing all elements from both sets. Since there is no overlap, the union will have 5+7 elements.
Therefore the answer is 12.
Aluminium Hydroxide contains elements of Aluimium, Hydrogen and Oxygen.
Magnesium sulfide contains two elements: magnesium and sulfur.
it contains nitrogen and oxygen. N2O4
Calcium carbonate contains three elements: calcium, carbon, and oxygen.
All matter contains elements that are contained in the periodic table. For example: food contains carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, and many other elements as minerals and vitamins; the water you drink contains hydrogen and oxygen; the air you breathe contains oxygen, nitrogen, carbon dioxide, hydrogen, and many other gases that contain elements; the clothing you wear, the paper you write on, the computer that you use are all made up of elements. Most of the elements found in matter are in the form of compounds, which are composed of two or more elements chemically combined.
If they are disjoint faces, then 6*4 = 24 vertices.If they are disjoint faces, then 6*4 = 24 vertices.If they are disjoint faces, then 6*4 = 24 vertices.If they are disjoint faces, then 6*4 = 24 vertices.
S orbital contains only 2 electrons and not elements.
The body contains 27 elements
