I have some conflicts with this problem as I think my teacher did it wrong. A speeder travelling at 34m/s passes a police at rest at the side of the road. The police accelerates at 1.82m/s^2. How long does it take the policeman to catch the speeder? He ha...

If the reverse reaction is favoured and it includes a solid as a reactant, the solid concentration is not going to increase as solids and liquids stay constant right? To determine which solution is most basics given [OH-] / [H30+], you take the -log and y...

Can someone explain this to me? In the reaction: --> AgCl(s)<_______ Ag+(aq) + Cl-(aq) the shorter arrow pointing to the right shows that the qe. mixture consists mostly of ______. ---> In the reaction HC2h302 + H20<_______ H30+ + C2h302-, when the concen...

Hmm... This does not make sense. I learned that anything over 5% error, we cannot accept so we have to use the quadratic formula. Here is a question I got 5.831%. It didn't use the quadratic formula and it still said to set x=0. Ka = 6.8x10^-4 HF = 0.2-x...

I really don't get this. The calculations shown don't make sense. Demonstrate that work is not a state function by calculating the work involved in expanding a gas from an initial state of 1.00: and 10.0atm of pressure to (a) 10,0 L and 1.0 atm pressure....

NY has 560 cars for 1000 residents. The current population of NY is 12,929,000 and rate of growth of the population is 0.02%. NY license plates consists of 4 letters followed by 3 digits. What year will they need to change the way they make license plates...

Hi I was just wondering how do you do inverse functions? example: Sin^-1 (5pi/6) Sin^-1 (3pi/2) Why does most of the answers only have 1 answer and is out of "RANGE"?

also if a catalyst is present at the initial introduction of reactants, how would the graph differ ?

you have to close the spaces and remove the brackets.

Are we allowed to set x = 0 if it is like 5.83%?

Hi I got 20, 000 years... The rate is 0.02% which is 0.02/100 ? then 7240240(1.02)^t = 456976000 1.02^t = 63.116 t = log 63.116/log 1.02 = 209.3 years How did you get that? Thanks!

Thanks for your help! Much appreciated :)!

and in 20K years... Will they still even have cars xD?

Sin^-1 sqrt(3)/2 Has only 1 answer. Why is 2pi/3 out of the range?
