The nuclear equation that describes the alpha decay of Polonium-210 can be written like this:
210/
84Po→206/82Pb+4/2 He
Molar mass K₂SO₄ = 174.259 g/mol
![n = \frac{m}{M}](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7Bm%7D%7BM%7D%20)
![n = \frac{15.0 g}{174.259g/mol}](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7B15.0%20g%7D%7B174.259g%2Fmol%7D%20)
![n = 0.0860](https://tex.z-dn.net/?f=n%20%3D%200.0860)
moles
hope this helps!
Hey there !
<span>Balanced equation:
1 MgS +1 Na2O = 1 Na2S + 1 MgO
</span>
MgS = 1
Na2O = 1
Na2S = 1
MgO = 1
Answer D
Answer:
Chemistry is the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
They answer questions like, like "What makes up this material?," "How does this material change when heated or cooled,?" What happens when I mix this material with another material,?" and "What rules determine how materials change in different situations?" What makes up Chemical X?
