Answer:
no. of moles of PbI₂ = 14 moles
Explanation:
Data Given:
no. of moles of HI = 28 moles
no. of moles of Pbl₂ = ?
Reaction Given
Pb + 2HI -------→ Pbl₂ + H₂
Solution:
To solve this problem we have to look at the reaction
Reaction:
Pb + 2HI -------→ Pbl₂ + H₂
2 mol 1 mol
So if we look at the reaction 2 mole of hydrogen iodide (HI) gives 1 moles of Lead iodide (PbI₂), then how many moles of Lead iodide (PbI₂) will be produced by 28 moles of hydrogen iodide (HI)
For this apply unity formula
2 mole of HI ≅ 1 moles of PbI₂
28 mole of HI ≅ X moles of PbI₂
By Doing cross multiplication
moles of PbI₂ = 28 moles x 1 moles / 2 mole
moles of PbI₂ = 14 mole
28 mole of HI will produce 14 moles of PbI₂
Answer:
They all vibrate, but they all move differently.
Explanation:
Similarities: They all consist of particles and vibrate, just at different frequencies.
Differences: The particles in solids move slowly and vibrate. In liquids, they move a bit quicker and slide past one another. They will also take the shape of the container they're in. In gases, they move freely at high speeds and also taking the shape of the container.
Hope this helped! :)
Answer:
White school glue is liquid because its long polymers can slide over and along one another. It does not flow easily, though; it is quite viscous. The addition of some chemicals—such as a borax solution (or sodium tetraborate decahydrate dissolved in water)—can cause cross-links to form between the polymers.
Explanation:
3. Atoms change into other atoms in chemical reactions.
The idea that you can transform one element into another was called alchemy, and was proven untrue a long time ago.
