CH3COOH + H2O = CH3COO- + H3O+ Acid acetic is a weak acid so not all of it will dissociate. The constant for acid acetic is 1.8 . 10^-5 therefore 1.8x10^-5=(x^2)/(0.2-x) x is the amount that disociated solve the equation and x is 1.88x10^-3 pH=-log(pH)=-l...

first find the common denominator of 6 so you get 2/6 + 5/6 then you add straight across to get 7/6 over 2/5. when you divide the fractions, take the denominator and flip it to then multiply straight across so, you have 7/6 * 5/2 = 35/12

so I was supposed to do Fres. X distance for 1 J = 1N*m. I had mixed the previous formulas up, I had the W for watts instead of Work. So my final answer for the work of the air resistance is actually 26N*500m = 13,000 J or 13 kJ. is that correct?

13 years ago

For finding Power, that's where I'll use 13kJ / 37,83 sec. right? = 343.64 watts.

The above answer is incorrect.. everything is right except v=9pi(h) differentiate both sides. gives you... dv/dt=9pi dh/dt 9/9pi= dh/dt. dh/dt= 1/pi

Say x is the number of boxes sold in week 1, then: Boxes in week 1: x Boxes in week 2: x + 5 Boxes in week 3: 2x + 10 Total boxes = 4x + 15 4x + 15 = 431 x = 104 So in week 1 there was sold x = 104 in week 2: x + 5 = 109 in week 3: 2x + 10 = 218
