Best ResponseYou've already chosen the best response.3Well which one are you thinking it is? I'll cross one off for you, beta emissions are unable to pass through concrete but it can pass through something like paper.

Best ResponseYou've already chosen the best response.3So it is not C

Best ResponseYou've already chosen the best response.0Its asking what it not is. So C would be the answer right?

Best ResponseYou've already chosen the best response.1Here's a hint: Beta particles are high speed electrons, travels faster, and are less heavily ionized than alpha particles.

Best ResponseYou've already chosen the best response.3C says cannot penetrate concrete so that's true the question asks what is not true

Best ResponseYou've already chosen the best response.0Thanks Zale it would be D

taramgrant0543664

Best ResponseYou've already chosen the best response.3And yes it would be D

Zale101

Best ResponseYou've already chosen the best response.1Yes it is D. because since beta particles are less heavily ionized then that makes it more penetrating than alpha particles. Alpha particles are thickly ionized and are less penetrating.

Best ResponseYou've already chosen the best response.0Given the following chemical equation, how many moles of carbon are necessary to react with 5.52 moles of SO2? 5C(s) + 2SO2 (g) arrow CS2 (l) + 4CO (g) 5.52 moles SO2 2.00 moles SO2 13.8 moles SO2 11.0 moles SO2 this one would be 13.8 right ? because the formula is 5.52molesSO2×5molesC2molesSO2=13.8

Best ResponseYou've already chosen the best response.0i just never know with this weird wording tbh

taramgrant0543664

Best ResponseYou've already chosen the best response.3That is referring to fission which is the splitting, fusion is the colliding of atoms

Best ResponseYou've already chosen the best response.0Given a solution with a pH of 2.8, what is the [H+] of the solution? 2.8 M 6.31 x 1012 M 1.58 x 103 M 11.2 M

taramgrant0543664

Best ResponseYou've already chosen the best response.3Yes it would be c [H+]=10^2.8 Which gives c

Best ResponseYou've already chosen the best response.0A solution is highly concentrated if there is: a large volume of solution a large amount of solvent and a small amount of solute a large amount of solute and a small amount of solvent a high density value for the solution

taramgrant0543664

Best ResponseYou've already chosen the best response.3Well when you think about it volume of solution doesn't matter because it could be at any volume and density value doesn't make sense for it either. Think about the difference between something dilute and something that is concentrated and that will sort out between B and C

Best ResponseYou've already chosen the best response.3dilute: a solution that contains a small proportion of solute relative to solvent concentrated: a solution that contains a large proportion of solute relative to solvent.

Best ResponseYou've already chosen the best response.0Calculate the change in freezing point when 116.8 grams of barium chloride are added to 250 grams of water. Kf = 1.86°C/m; Kb = 0.512°C/m 4.17°C 12.5°C 8.35°C 0°C last question im stuck on

taramgrant0543664

Best ResponseYou've already chosen the best response.3ΔT= Kf · m · i So ΔT is the change in temperature that you solve for Kf is given m is the molarity to find this you need to find the moles of barium chloride and you need to convert 250g of water into kg. then you do moles divided by kg of water to find m i is the van't Hoff dissociation factor so BaCl2 dissociates into Ba2+ +2Cl let me double check this i, I can't quite remember the rule but the rest is right I'll look it up quick

taramgrant0543664

Best ResponseYou've already chosen the best response.3So BaCl2 breaks into Ba2+ and 2Cl so it breaks into 3 parts so i is 3 but NaCl for example breaks into Na+ and Cl so i=2

taramgrant0543664

Best ResponseYou've already chosen the best response.3If we put it all together ΔT= Kf · m · i ΔT= (1.86)m(3) so m just needs to be found

Best ResponseYou've already chosen the best response.3116.8g/ molar mass of BaCl2 (208.233)=0.5609 0.5609/ kg of water so 250/1000 this =2.24
