Which of the following could result from the fission of carbon?

1 answer:

3 0

In nuclear reactions, there are can be two kinds: nuclear fission and nuclear fusion. From the word itself, fusion is combination while fission is breaking. Nuclear reactions are different from chemical reactions. Whereas chemical reactions from compounds by exchanging elements, nuclear reactions add or eliminate subparticles, like protons, neutrons and electrons.

So, when carbon is split up, their protons should add up to 6, which is its atomic number. From the choices, the only obvious answer is two lithium atoms. To investigate further, lithium has an atomic number of 3. So, two lithium atoms would equal to 6.

Therefore, the answer is two lithium atoms.

Answer:

The reactant/reagent that would be most atom economical is EtI (Ethy Iodide) and KOH (potassium oxide) as base

This is because the iodo group are weak base hence they have a good leaving character (i.e they are unstable on their own ) which would increase the rate of reaction and the strong base KOH give the most atom economical

<h3>Explanation:</h3>

Step 1: Define

[Given] 7.2 × 10¹⁵ atoms Pb

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[DA] Set up: $\displaystyle 7.2 \cdot 10^{15} \ atoms \ Pb(\frac{1 \ mol \ Pb}{6.022 \cdot 10^{23} \ atoms \ Pb})$
[DA] Multiply/Divide [Cancel out units]: $\displaystyle 1.19562 \cdot 10^{-8} \ mol \ Pb$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

1.19562 × 10⁻⁸ mol Pb ≈ 1.2 × 10⁻⁸ mol Pb

Explain in a short sentence how you can tell if a reaction is a double replacement reaction.

Monica [59]

Explanation:

In a double displacement reaction, there is an actual exchange of partners to form new compounds.

The reaction is given as shown below:

AB + CD → AD + CB

One of the following conditions serves as the driving force for a double replacement reaction:

Formation of an insoluble compound or precipitate
Formation of water or any other non-ionizing compound
Liberation of a gaseous product.
