I believe its D.180MG
*Update* I tried following a similar example in my textbook using the Nernst equation but still got the wrong answer log(xM/0.135M) = 2(0.180V)/-0.0592 = -6.081081081 xM/0.135M = 10^-6.081 = 8.29E-7(0.135M) = 1.12E-7M = x = [Ag+]anode 1.12E-7(2) = 2.24E-7M
I tried 4.0x10^-5 with a slightly different first value (5.35E-2 vs 5.15E-2) and it was still marked as incorrect. How do i get the correct answer

not answered. Question asked: express sinx + cosx in term of a.
answers are correct. As a rule of thumb, adjectives go AFTER the noun (chico perezoso. In an enumeration (la primera persona, etc) or poetry, the adjective goes BEFORE (hyperbaton)
You can also word the question as an informal command (tu) Describe como a) eres tu b) es _______ (name)

Ok I understand...:-)
****There's something you should know though...I wrote the reaction like how you did. (CH4+ C2H6) + 2O2 ==> CO2 + H2O and my teacher said H2O is not part of the residual gases. She said H2O should be replaced with O2. (CH4+ C2H6) + 2O2 ==> CO2 + O2 ****
Lol when you explain it. Not when my teacher teaches me, I never understand a word she says. Anyways thanks alot for staying up to help me. There's something yo should know though...I wrote the reaction like how you did. CH4 + 2O2 ==> CO2 + H2O and my
Yes the answer to the first question was correct, that's what my teacher got too... but she did it like this. Either way its correct. x + y = 24cm^3 x + 2y = 32cm^3 then 32 - 2y + y = 24cm^3 32-y = 24cm^3 y= 8cm^3(volume of ethene) x + 8 = 24cm^3 x=
If yes...Here it is... 24cm^3 of a mixture of methane and ethane were exploded with 90cm^3 of oxygen. After cooling to RTP the volume of gases was noted and it decreased by 32cm^3 when treated with KOH. Calculate the composition of the mixture.
The one from last week?
ok thanks
I thought it was similar so I wrote... x + y = 30cm^3 x + 2y = 61.5cm^3 i.e 2x + 2y =60cm^3 x + 2y = 61.5cm^3 therefore x= -1.5cm^3(volume of methane) and y= {61.5-(-1.5)}/2= 31.5cm^3(volume of ethane) However my teacher said the volume i got for ethane is
Thank you DrBobb22
F= 500N , m= 10kg , t= 2.1s , a=? , v(f)=? F= (m)(a) therefore a= F/m so a= 500/10= 50ms and v= u(i) + (a)(t) so v(f)= 0 + (50)(2.1)= 105ms note=== v(f) is final velocity and v(i) is initial velocity.
Thanks for trying :)
Sorry, I haven't done grammar in years! :)

This is similar to 13 or 14, I don't remember which number, but the one with the presenters and the notes. So, I would suggest 16 a.
I think this is one is also right, but, please make sure you check all of these with your teacher.
Again, I believe this to be correct.
Yes, that is correct.
