In the reaction $2 N a O H + H_{2} S O_{4} \to 2 H_{2} O + N a_{2} S O_{4}$ $2NaOH+H_2SO_4 -> 2H_2O+Na_2SO_4$ , how many grams of sodium sulfate will be formed if you start with 200.0 grams of sodium hydroxide and you have an excess of sulfuric acid?
Using the limit definition, how do you differentiate $f (x) = \frac{3 x}{7 x - 3}$ $f(x)=(3x)/(7x-3)$ ?
