6. balance the following equations (3 points)a. fecl3 + naoh  fe(oh)3 + naclb. c2h2 + o2 -- co2 + h2oc. fe2o3 + h2 -- fe + h2o

The answer is

a.  FeCl3 + 3 NaOH = Fe(OH)3 + 3 NaCl

b. 2 C2H2 + 5 O2 = 4 CO2 + 2 H2O

c. Fe2O3 + 3 H2 = 2 Fe + 3 H2O

To balance equations you basically have to make sure each element has an equal amount or number on each side of the equation. If you need more help understanding this, feel free to ask.

b.

the accuracy of the data.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
