Can't figure this one out. Here's the problem. Solid molybdenum (VI) oxide reacts with gaseous xenon difluoride to form liquid molybdenum(VI) fluoride, xenon gas, and oxygen gas. Write the Qc for this reaction. I know Qc is products over reactants and pure liquids and solids are not...

Oh. I was just looking at solubility rules in my book.

Tried but couldn't find it

MgCl2 + Cu(NO3)2 I need the full and net ionic equations for this. I know NO3 is soluble and Cl is soluble too since there's no Ag, Pb, or Hg. Not sure how to write them out though.

woops, sorry didnt know it was going to be huge.

I need to write the lewis dot structure along with the 3 resonance forms for CH3CNS. This is what I had but it was wrong. Not sure what to do. Thanks.

Seems a lot easier than I thought. Seems too easy. Thanks though.

Ok. I already used conservation of momentum in the beginning. Don't I need to show more just momentum is conserved for this.

What I'm trying to show is that when I person gets hit by a bullet in real life, they do not go flying backwards. So I guess I'd be trying to show how the force of a bullet is not enough to send a person flying backwards.

bump. So do I find the kinetic energy next? Or the force of the bullet? Something else?

Hahaha, very good point. Not quite sure to go from here though. I figured out the momentum of the bullet, the time it took for the target to hit the ground after getting hit, the distance he traveled backwards after getting hit, and the speed of the target after getting hit. The acceleration...

I did .148 m/s = x/.452 s and got x = .066896 m Seems like too low of a number though.

Ok so I guess I use v=d/t, but I first have to find the velocity after impact, right? And the time to fall. Wouldn't I use conservation of momentum to find the speed of the 104 kg target after getting shot? I tried that earlier. I did... 104kg (v) = 15.4 kg m/s and got v2 = .148...

Yes, I also got 15.4 for the momentum. And what exactly do you mean how fast does the target recoil from the shot? Yeah he does not go skidding. Just gets hit by the bullet and then flies backwards landing on his back, not skidding. Wouldn't I need to find acceleration first in order to find...

I'm proving that the force of a bullet is not actually enough to send a person flying backwards like you see in the movies. These are the variables I have so far. I'm not sure if all of them are really necessary to solve this. distance between gun and person getting shot = 2.45 m mass...
