Answer:
C. Symbol
Explanation:
The letters CU is a chemical symbol used to identify the said metal.
Elements are distinct substances that cannot be split up into simpler substances. Such substances consists of only one kind of atom. The numbers of elements know till date exceeds hundred. Every matter is a combination these various elements.
In the world of science, each of the element is symbolized by a capital letter or capital letter followed by a small letter usually derived from their Greek, Latin or English names.
For copper, it is derived from a latin word Cuprum and its symbol is Cu.
A substance that has a molecular structure consisting entirely of a large number of similar units bonded together
Answer:
<em>Scheme attached</em>
Explanation:
<em>Trans</em> effect is involved in this synthesis. As in the reactions of planer metal complexes, trans effect dominates the stereo-chemistry of the product.
<em>Trans</em> effect
The role of the element present in trans position to the element to be substituted is called the trans effect. The nature of the ligand in trans position effects the substitution, if it has high <em>trans</em> effect it make the substitution difficult.
So when we attach NH₃ first to the ligand it make the trans substitution difficult, hence <em>cis</em> product will be formed.
As NO₂ has very low <em>trans</em> effect, so it doesn't effect the substitution and the <em>trans</em> product will be formed as usual.
Answer:
B carbon
Explanation
Lewis structure or dot structure is an easy way to get the bonding details of atoms in a molecule. If we talk about methane molecule carbon is central atom with four electrons that are bonded to four hydrogen atoms and each bond is single covalent bond.
Please see attached figure,
Hope it helps!
That's a ionic compound because it has a metal and polyatomic parts within the chemical formula.
