my diabetic grandma just had a double bypass. she made it through, but had to be put on the ventilator because she wasn't able to breathe on her own. i'm wondering if this is normal for patients who have just come out of this type of surgery? is it a bad sign, or will she be ok? the last i heard, she is doing better, but i just wanted to know about what's normal to experience after having just come out of surgery. thanks in advance!

I need some help with one problem, thanks in advance.

Please show the verification that the function is a solution to the differential equation.
y'-2ty=1; y=e^(t^2) ∫e^(-s^2)ds+e^(t^2)

The upper bound for the integral is t and the lower bound is 0.

How many mL of water must be added to 45.0 mL of a 1.25 M HCL (aq) to lower the concentration to 1.00 M?


Do you just set it up as 45mL/1.25 = X/1.00M and X=36?
That seems too easy to be true. How would you approach this type of question?
