Answer:
Another view could be from this definition: (Electron Sea Model) : The metallic bond consists of a series of metals atoms that have all donated their valence electrons to an electron cloud that permeates the structure. This electron cloud is frequently referred to as an electron sea. It might help to visualize the electron sea model as if it were a box of marbles that are surrounded by water. The marbles represent the metal atoms and the water represents the electron sea.

Answer:
The reducing agent is Zn.
Explanation:
Let's consider the reaction between zinc and hydrochloric acid.
Zn(s) + 2 HCl(aq) ⇄ ZnCl₂(aq) + H₂(g)
This is a redox reaction, which can be divided in 2 half-reactions: reduction and oxidation.
In the reduction, H⁺ gains electrons and it is considered the oxidizing agent.
2H⁺ + 2 e⁻ ⇒ H₂
In the oxidation, Zn loses electrons and it is considered the reducing agent.
Zn ⇒ Zn²⁺ + 2 e⁻
Answer:
E. 1.18x10^4nm/ms^2
Explanation:
The aceleration of the train is given in m/s². We need to conver, first, the meters to nm and then, the seconds to ms as follows:
11.8m/s² * (1x10⁹nm / 1m) = 1.18x10¹⁰nm / s²
Now, as 1s is equal to 1000ms:
1.18x10¹⁰nm / s² * ((1s)² / (1000ms)²)) =
1.18x10⁴nm / ms²
Thus, right option is:
<h3>E. 1.18x10^4nm/ms^2</h3>
