Answer:

<u>Chemical Reaction</u>

Atoms are rearranged during a chemical change to create a new substance The new substance is formed during a chemical reaction cannot be changed back to its original state During a chemical reaction, the chemical bonds are broken and new chemical bonds form

<u>Nuclear Reactions</u>

Nuclear reactions are defined as the reaction in which there occurs change in the nucleus of an atom due to change in number of protons or neutrons of an atom.

Answer:

Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical changes involve only a rearrangement of electrons.

Explanation: Hope this helps

Which of the following atoms forms an ionic bond with a sulfur atom? (Points : 3)
elena-s [515]
Ionic bonds are formed when there is complete transfer of valence electrons between two atoms.

Electronegativity tells the trend of an atom to atract electrons.

You should search for the complete set of rules that indicate whether an ionic or covalent bond happens.

There are two relevant rules to state if whether an ionic bond will happen:

- When the difference of electronegativities between the two atoms is greater than 2.0, then the bond is ionic.

- When the difference is between 1.6 and 2.0, the bond is ionic if one of the elements is a metal.

You need to list the electronegativities of the five elements (there are tables with this information)

Element  electronegativity

Cu:    1.9
H:      2.2
Cl      3.16
I:        2.66
S:      2.58

Differences:

Cu / S: 2.58 - 1.9 = 0.68
H / S: 2.58 - 2.2 = 0.38
Cl / S: 3.16 - 2.58 =0.58
I / S: 2.66 -  2.58 = 0.08

 Those differences are too low to consider that the bond is ionic.

Then the answer is that none of those atoms forms an ionic bond with sulfur.

Write the balanced electrochemical reaction for when zinc reacts with a copper solution. Label what is being oxidized and what i
Fed [463]

The balanced equation would be Zn + Cu^{2+} ---- > Cu + Zn^{2+}

<h3>Electrochemical equations</h3>

Zn reacts with Cu solution according to the following equation:

Zn + Cu^{2+} ---- > Cu + Zn^{2+}

In the reaction, Cu^{2+} is reduced according to the following: Cu^{2+} + 2 e^- -- > Cu

While Zn is oxidized according to the following: Zn - 2e^- --- > Zn^{2+}

Thus, giving the overall equation of; Zn + Cu^{2+} ---- > Cu + Zn^{2+}

You have identified a substance to be solid in nature. which characteristics will justify your identification?
weeeeeb [17]
This question includes four answer choices: A. definite volume, highest molecular motion, highest kinetic energy B. indefinite volume, least molecular motion, highest kinetic energy C. definite volume, least molecular motion, lowest kinetic energy D. definite volume, no molecular motion, lowest kinetic energy Solids do not have the highest molecular motion (on the contrary they have the least molecular motion), so you can discard option A. Solids have a definite volume and the highest kinetic energy (given that they have the least molecular motion), so you discard option C. Molecules always have a vibrational motion, so you discard option D. Option C, have only characteristics that correctly describes a solid: definite volume, least molecular motion, lowest kinetic energy. Therefore, the answer is the option C. <span /><span>
