Answer:
a. True
Explanation:
The bonds between atoms are called chemical bonds. These bonds act as though they were a spring holding these atoms together.
When the atoms in a given bond are compressed by decreasing their distance of separation from their equilibrium position, a force provided by the bond tries to prevent these atoms from getting too close than usual. If on the other hand the atoms are stretched by increasing their distance of separation from their equilibrium position, a force provided by the bond tries to pull these atoms together again. This behaviour of the bond is what makes it to be considered as being similar to a spring.
<span>sulfur, because it's in the same group
Groups are columns of a periodic table. Both oxygen and sulfur are in the same group, and groups, such as halogens and noble gases, generally display similar properties. Periods are ordered by ascending atomic number, and don't typically display the same level of similarity. </span>
They have similar chromosomes
To develop the chemical formula of a substance or compound in this regard, one only needs to write the chemical symbol for each of the element present and write as subscript to each symbol the number of atoms of that element. For nitrobenzene, as described above, the chemical formula should be,
C₆H₅O₂N
Answer:
1.18 × 10⁷ c
Iron is the anode and zinc is the cathode.
Explanation:
Let's consider the reduction of Zn²⁺.
Zn²⁺(aq) + 2 e⁻ ⇒ Zn(s)
<em>How many coulombs of charge are needed to produce 61.2 mol of solid zinc?</em>
<em />
We can establish the following relations:
- When 2 moles of electrons circulate, 1 mol of Zn is produced.
- 1 mole of electrons have a charge of 96468 c (Faraday's constant).
Then, for 61.2 mol of Zn:
<em>Identify the anode and cathode when plating an iron nail with zinc.</em>
The anode is where the oxidation takes place and the cathode is where the reduction takes place.
Anode (oxidation): Fe(s) ⇒ Fe²⁺(aq) + 2 e⁻
Cathode (reduction): Zn²⁺(aq) + 2 e⁻ ⇒ Zn(s)
