24. Hydrogen peroxide can decompose to water and oxygen according to: 2H2O2 (l) + -----------> 2H2O(l)+ O2 (g) ^ H = -196 kJ What is the enthalpy change accompanying the reaction of 5.00 g H2O2 (l) according to the above mentioned reaction ?
Sorry I don't understand how to get the second derivative, I gsolved the first derivative already
I need help with finding first and second derivative--simplify your answer. Y=xtan(x) I solved first derivative xsec^2(x) + tan(x) I don't understand how to get the first...can someone show me the steps with explanation?
Did I do this problem right? Find the first and second derative-simplify your answer. y=xtanx y'= (x)(sec^2 x)+(tanx)(1) y'= xsec^2 x + tanx y"= (x)(2secx)(secxtanx)+sec^2 x + sec^2 x y"=2xsec^2 x tanx + 2 sec^2 x
I plug in the numbers into the formula that I used, but I don't get the same answer. Here's what I did, maybe you can tell me what I did wrong. (likely a dumb algebra mistake) f"(x) = lim-->0 f'(x+h)-f'(x)/h =(1/4(x+h)+1)^2 - (1/4x+1)^2/h =(1/16x^2+32xh...
To solve the first step I used the equation f'(x)=lim h-->0 f(x+h)-f(x)/h Can I use this same formula to solve for the second derivative?
Find the first and second derivative - simplify your answer. y=x/4x+1 I solved the first derivative and got 1/(4x+1)^2 Not sure if I did the first derivative right and not sure how to do the second derivative.
A television set is on sale for $780 cash, or 25% deposit and $85 per month for 8 months. How much can be saved by paying cash? How much is charged in interest? Calculate the annual rate of simple interest charged? Working out please:)
I solved this problem, can someone check it to make sure I did it right. There are two parts to this intrepation and estimate of the value. Let C(t) be the total value of the US currency (coins and banknotes) in circulation at time, t. The table gives values of this function f...
Hi I need help and I appreciated it. am kind of confused and dont what to write. I have to do journal where I see, read, explore, observe about Intersecionality. How can I start writing about this? Thanks
