Jun 17, 2024 · hii guys, i need explanation about M1V1=M2V2 concept? This is used for titrations, for example: In HCl + NaOH --> NaCl + H 2 O, equivalent moles of HCl and NaOH are needed …

May 23, 2025 · Oh that's quite annoying but i'll tell you what i did (even though it's probably wrong) So we know that the final KE of the proton if 4/9 of the initial KE so we can say …

First of all I wrote down m1u1 + m2u2 = m1v1 + m2v2 and e=(v2-v1)/(u2-u1) because thats what we know. I have tried simultaneous equations, rearranging, and all sorts to get rid of v2 and v1 …

Nov 27, 2020 · Have you used m1v1 = m2v2? I didn’t use that but I just saw it online I didn't do it that way but I using that equation just now I get the same answer as I did, and it's not 50cm3

Apr 21, 2021 · m1u1 + m2u2 = m1v1 + m2v2 take 1 to be player A and 2 to be player B for final momentum (v) their masses will be combined so add them.. (169v) should be on the r.h.side …

M1V1 = M2V2 a b EXPERIMENT 4 Appendix A REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE STUDENT’S ...

Jun 17, 2024 · Calculate the Concentration of the Sodium Hydroxide Solution in a) Moles/Litre (molarity) b) grams/Litre" And I'm really struggling trying to figure out how:/ Apparently I'm …

As far as I can remember from when i did M1...the main ones you need are v = u + at s = 1/2 (u+v)t s = ut + 1/2 at^2 v^2 = u^2 + 2as F = mu.R when sliding F <or= mu.R generally F = ma …

CLM: m1u1 + m2u2 = m1v1 + m2v2 v2 = (m1u1 + m2u2-m1v1)/m2 Taking A's velocity as positive: u1 = 3, m1 = 0. ...

Jun 6, 2025 · In the collision, the particles join to form a single particle C. Find the speed of C immediately before the collision. m1u1+m1v1=m2u2+m2v2 3(4)+2(1.5)=3v+2v 15=5v v=3ms^-1 …
