A 20.00 mL sample of HCl with unknown concentration is titrated with 0.50 M NaOH. a) Write out the balanced equation

b) Write out total ionic equation

c) Write out net ionic equation

d) If 15.0 mL of NaOH was required to reach the equivalence point (point where phenolphthalein turns pink) what is the concentration of the HCl solution. Please include some of your work as best as you can in the answer for full marks.

Nitrogen dioxide reacts with water to form nitric acid and nitrogen monoxide according to the equation: 3no2(g)+h2o(l)→2hno3(l)+no(g) part a suppose that 4.2 mol no2 and 0.50 mol h2o combine and react completely. which reactant is in excess? express your answer as a chemical formula. nothing

The following reaction shows the products when sulfuric acid and aluminum hydroxide react. al(oh)3 + h2so4 → al2(so4)3 + h2o the table shows the calculated amounts of reactants and products when the reaction was conducted in a laboratory. sulfuric acid aluminum hydroxide initial amount of reactant 40 g 15 g theoretical yield of water from reactant 14.69 g 10.38 g what is the approximate amount of the leftover reactant? 11.73 g of sulfuric acid 10.33 g of sulfuric acid 11.12 g of aluminum hydroxide 13.67 g of aluminum hydroxide

How does concentration affect reaction rate
