The causes of the 1914-1918 First World War can be categorised into militaristic factors, alliances, imperialism and nationalism. The competition between nations to develop superior militaries between Bri...

n(HCl) = 0.05 dm^3 x 2 mol dm^-3 = 0.1 mol 

Ratio HCl : NaOH = 1 : 1 = 0.1 mol : 0.1 mol 

c(NaOH) = 0.1 mol / 0.025 dm^3 = 0.4 mol dm^-3

First of all, we have to use the product rule, since two things are multiplied together.  The product rule states that d/dx (u*v) = vu' + uv'

Let u = (4x+3)⁵  v = sin(2x)

Now, to ...
