AI Thread Summary
Grinding a mixture of powdered aluminium with potassium chlorate is dangerous due to the highly reactive nature of both substances. The process can lead to the formation of aluminium oxide and the release of toxic chlorine gas, which poses serious health risks. Additionally, the potential for explosive reactions exists when these materials are combined and ground together. The risk is heightened by the fact that aluminium can become passivated, further complicating the reaction dynamics. Understanding these dangers is crucial for safety when handling such materials.

hi all,

im wondering why it is dangerous to grind a mixture of powdered aluminium with potassium chlorate in a mortar and pestle.

any help would be great.

I'm not sure of the exact answer here but there are a couple of things i can think of. The reactive nature of potassium is dangerous but its more likely somethign to do with the aluminium reacting with the chlorate giving Aluminium oxide because aluminium in passivating and releasing chlorine gas which is highly toxic. I'm not 100% sure if that's the answer your looking for though, that's just off the top of my head.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
