Answer: First Choice

Explanation:

It is the first choice because molecules tend to decrease motion when they are being converted into a solid but when in liquid or vapor they are increased by the moving atoms grouped and separated from each other.

Which set of changes does not involve breaking or forming chemilcal bonds
sineoko [7]
<h2><u>Answer:</u></h2>

It wasn't an adjustment in the condition of issue on the grounds that the vitality in the can did not change. Additionally, since this was a physical change, the atoms in the can are as yet similar particles. No synthetic bonds were made or broken.  You added enough vitality to make a stage change from strong to fluid.  

The main changes recorded which don't include framing or breaking substance bonds would bubble and liquefying. Bubbling and liquefying are physical changes as opposed to synthetic changes, so no new items are shaped.

Use the equation 2cu+o2=2cuo to find how many miles of copper react to form 3.64 mil cuo
Firlakuza [10]
<h3><u>Answer;</u></h3>

3.64 moles

<h3><u>Explanation;</u></h3>

From the equation;

2Cu + O2 → 2CuO

Mole ratio of Cu : CuO = 2: 2 equivalent to 1: 1

Moles of CuO = 3.64 Moles

Therefore;

moles of Cu will be ;

3.64 × 1 = 3.64 moles

Moles of Cu = <u>3.64 moles </u>

Which equation demonstrates that nuclear fusion forms elements that are heavier than helium
GrogVix [38]

Answer: The correct option is 2.

Explanation: There are two types of nuclear reactions:

1) Nuclear fission: These reactions are defined as the reactions in which a heavier unstable nuclei breaks into two or more smaller stable nuclei.

2) Nuclear fusion: These reactions are the ones where two smaller nuclei fuse together or combine together to form a larger nuclei.

In the question, we need to find the fusion reaction which forms elements heavier than helium.

Option 1: In this fusion reaction occurs but the nuclei is Helium itself.

Option 2: In this also fusion reaction occurs and the nuclei is heavier than Helium which is Neon.

_8^{16}\textrm{O}+_2^4\textrm{He}\rightarrow _{10}^{20}\textrm{Ne}

Option 3 and Option 4: These two reactions are nuclear fission reactions of Uranium-235 because one heavier element is breaking into more than 2 products.

Hence, the correct option is 2.
