Answer:
d. magnesium sulfide, mgs
Explanation:
Ionic bonds or also called eletrovalent bond is one of the chemical bonds that forms between the atoms of molecules or compounds. It is the kind of bond that forms between a positively charged atom and a negatively charged atom. The positive atom transfers electrons to the negative atom.
In this question, Magnesium Sulfide, MgS is a compound whose atoms are held together by ionic bonds. The magnesium ion (cation) transfers its two valence electrons to the sulfur ion (anion) to form the stable MgS.
The answer of the given question above would be option C. Based on the example of a Hertzsprung-Russell diagram that is shown, what can we say about white dwarfs is that, they are <span>relatively dim or faint, but very hot. Hope this answers your question. Have a great day ahead!</span>
<span>The net ionic equation for the reaction of alum (KAl(SO4)2.12H2O.) and KOH is </span>the solid AlOH3 formed.
<span>The total number of nodes = n-1.
a) In your case for the 5 d orbital 5 - 1 = 4 nodes.
b) The l quantum number for a d orbital is 2. Therefore you will have 2 angular (planar) nodes.
c) You have 4 nodes, 2 of which are angular. Therefore, you will also have 2 radial nodes.</span>
Answer:
A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. ... In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
