What is the % yield if 12g of magnesium is dissolved in hydrochloric acid to produce 20g of magnesium chloride?
First we need to write the balanced equation for the reaction. In this case it is Mg + 2HCl -> MgCl2 + H2. Now we need to work out the maximum theoretical yield of MgCl2
Differentiate the function f(x) = 2x^3 + (cos(x))^2 + e^x
When differentiating a function that is the sum of three different parts we can differentiate each part separately:
a) 2x3 is easy to differentiate. We remember the rule d/dx[axb
