Let's write the balanced chemical reaction for this:

K₂CrO₄ + Pb(CH₃COO)₂ --> PbCrO₄ + 2 CH₃COOK

The products are lead(ii) chromate and potassium acetate. As you can notice, there is an exchange of ions involved for both reactants. This type ofreaction is called the <em>double-replacement reaction or also called metathesis</em>.

What is the difference between Nuclear Fission and Nuclear Fusion? Also any examples of them
stealth61 [152]

Answer:

Hiya there!

Explanation:

Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

For example, uranium can fission to yield strontium and krypton. Fusion joins atomic nuclei together. The element formed has more neutrons or more protons than that of the starting material. For example, hydrogen and hydrogen can fuse to form helium.

<em><u>Hope this helped!</u></em> :D

Calculate how many grams of oxygen form when 2.72 g of KCIOg reacts completely given the
34kurt

1.06g

Please refer to the image attached.

You first find the number of moles (n) for KClO3 as you have been given the mass. So n = mass/Mr gives you the moles that is 0.022 mol

Next you use the ratio 2:3 as per the equation where it's 2KClO3 ---> 3O2 so you just cross multiply and get the moles for oxygen.

Now that you know the number of moles for oxygen, you can use the same moles equation that you used earlier to find the mass. mass=n×Mr and so you get the answer as 1.06g of oxygen.
