From my research and understanding of roller coasters, their speed is mainly impacted by the force of gravity and it works on the basis of potential energy build up into kinetic energy. Therefore, my question surrounds the idea of safe speeds on coasters. Because a roller coaster car is only...
I am writing a paragraph on astrophysicists. I want to incorporate a connection between the physics that we are learning and an astrophysicist's use of the same principles in their studies. Unfortunately, there is not much information about this on the internet.
What I have found is that...
Because in part A of the question I determined the moles of ZrCl4 using this formula: n = PV / RT and then used the mole ratio to convert to Cl2.
n = (50) (0.200) / (8.3145) (623.15) * 2mols Cl2 / 1mol ZrCl4 = 0.003860124
Hi all,
While studying for my exam (and doing review questions) I came across a problem that I couldn't solve:
5. Zirconium metal and chlorine gas react to form zirconium (IV) chloride
Zr + 2Cl2 = ZrCl4
a) What volume of chlorine gas must be used at 350 degrees Celsius and 50 kPa to produce...
Here is the question: If 75.0 g of potassium alum is obtained from 5.00 g of aluminum, what is the percent yield?
This is what I've done so far, but I'm not sure if it is fully correct:
5.00g Al x (1/26.98156) x (1/1) x 258.207 = 47.84882537g potassium alum
Wouldn't this then be the...
