Homogeneous catalyst - catalyst is in the same phase as the reactants. Heterogeneous catalyst - catalyst is in a different phase as the reactants. What ...

First we start off by seeing that we are multiplying together two functions both containing x, so we want to apply the product rule. As we know the product rule is (f(x)g(x))'=f(x)g'(x)+f'(x)g(x) so we ca...

First multiply top and bottom by conjugate of denominator, (7-3√5), and expand(3 + 2√5)(7 - 3√5)/(7 + 3√5)(7 - 3√5)(21 + 14√5 - 9√5 - 30)/(49 + 3√5 - 3√5 - 45)Simplify top and botton(-9 + 5√5)/4Write in r...

The threshold frequency is the minimum frequency a photon can be and still just overcome the work function (Φ) of a particular material. The threshold frequency is directly proportional to the work functi...

Of course, allow me to read through it or walk me through it and I will aid you in it and advise on appropriate methods where possible
