Answer:
7.71x10^23 molecules
Explanation:
Avogadro's # = 6.022x10^23
1.28 mol SiO2 x 6.022x10^23/ 1 mol SiO2 = 7.71x10^23 molecules
From the Law of Boyle for gases you know that the pressure and the volume of gases are inversely related. That, means that you can state PV = constant. And that implies that if P has a linear relation with the number of particles (which is what the straight line means), then V has the same kind of relation.<span> So, the relationship of volume and number of partilces will have a similar graph.</span>
A. Chemical energy can be in many forms including in the chemicals found in food
In health our body pH is between 7.35 and 7.45, so minimally alkaline.
Hope this helps!!!
