Answer:

The correct feedback Zoe will have from this diagrammatic report will be the option B, which is the charge of the purple circles, should be positive because they represent the nuclei.

Explanation:

Metals have fewer electrons in their outermost electron shells, which make them be good electron givers or better reducing agent, also due to their low ionization energy. Therefore, metals tend to become positively charged nucei after losing electrons to the neighboring atoms.

In the case of the metallic bond, the neighboring atoms are still metals. The big purple circles which represent the bigger metallic atoms should be marked with a positive sign, while the small circles in between the bid circles should be marked with negative signs.

What term best defines the splitting of nuclei into smaller fragments due to the bombardment of neutrons?
Andre45 [30]
Well the knowing what the answer choices mean would be most helpful for this problem:

a.  The definition of "Fusion" in general means bringing things together into one unit. In biology, Fusion sometimes refers to cellular fusion, the bringing of two or more uninuclear (cells with one nucleus) together to form multinuclear cells.
B. Fission is almost the opposite of "fusion" in that it is the action of dividing or splitting into two or more parts. This sounds like fission of a heavy nucleus to me.
c. molecular blending forms polymers. So this choice is incorrect.
d. atomic rebonding- when atoms on different molecules combine to form diatomic ions.

hope this helped!

A sample of pure NH4HS is placed in a sealed 2.0-L container and heated to 550 K at which the equilibrium constant is 3.5 x 10-3
Zolol [24]

Answer:

The mass of NH_{3} in the container is 2.074 gram

Explanation:

Given:

Volume of NH_{4} HS    V = 2 lit

Equilibrium constant k _{eq} = 3.5 \times 10^{-3}

The reaction in which NH_{3} is produced

  NH_{4} HS ⇄ NH_{3} + H_{2}S

Here equal moles of NH_{3} and H_{2}S is formed.

From the formula of equilibrium constant,

  k_{eq} = (NH_{3})(H_{2}S )

   x^{2} = 3.5 \times 10^{-3}

     x = 0.061 M

Above value shows,

   NH_{3} = 0.061 \frac{moles}{L}

So in 2 L no. moles of NH_{3} = 0.061 \times 2 = 0.122 moles.

So mass of 0.122 mole of NH_{3} is = 0.122 \times 17 = 2.074 g

Therefore, the mass of NH_{3} in the container is 2.074 gram

Ignore the answer I have selected but please help!! Ty in advance, also please explain
weeeeeb [17]

Answer:

Iodine is most reactive because it is very close to having a "full shell" which is 8 electrons so they are "eager" to gain the last electron to became balanced, so that makes it the most reactive. Hope that helps:)
