<u>Answer:</u> The mass percent of lead in lead (IV) carbonate is 63.32 %
<u>Explanation:</u>
The given chemical formula of lead (IV) carbonate is ![Pb(CO_3)_2](https://tex.z-dn.net/?f=Pb%28CO_3%29_2)
To calculate the mass percentage of lead in lead (IV) carbonate, we use the equation:
![\text{Mass percent of lead}=\frac{\text{Mass of lead}}{\text{Mass of lead (IV) carbonate}}\times 100](https://tex.z-dn.net/?f=%5Ctext%7BMass%20percent%20of%20lead%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20lead%7D%7D%7B%5Ctext%7BMass%20of%20lead%20%28IV%29%20carbonate%7D%7D%5Ctimes%20100)
Mass of lead = (1 × 207.2) = 207.2 g
Mass of lead (IV) carbonate = [(1 × 207.2) + (2 × 12) + (6 × 16)] = 327.2 g
Putting values in above equation, we get:
![\text{Mass percent of lead}=\frac{207.2g}{327.2g}\times 0100=63.32\%](https://tex.z-dn.net/?f=%5Ctext%7BMass%20percent%20of%20lead%7D%3D%5Cfrac%7B207.2g%7D%7B327.2g%7D%5Ctimes%200100%3D63.32%5C%25)
Hence, the mass percent of lead in lead (IV) carbonate is 63.32 %
Answer:
The last answer would be correct because if you have ever done it before you would know that rubbing your feet (just like the rubbing of ice crystals) on the carpet will create the energy you need, then once you touch the metal it creates that spark!
Explanation:
hoped that helped-I would be thankful for brainliest ;)
Answer: Balance, multiply, find ratio
Explanation:
Balance the equation to be able to multiply correctly and accurately, multiply, and this will give you the molar ratio
Answer:
The evidence showing that there is a chemical reaction taking place is the instantaneous temperature drop once the cold pack is shaken.
Explanation:
When an athlete applies a cold pack to the injury, they shake it before, mixing the water and <em>ammonium-nitrate fertilizer</em> inside the cold pack. This mixing is an endothermic reaction, which means it absorbs heat. In turn, the temperature falls to 35 F for around 10 minutes.
