PLS HELP ME W THIS Directions : Consider the following balanced reaction and answer the corresponding questions : C 3 H 8 + 5O 2 ... > 3 O 2 + 4 H 2 O 23 , If you have 25 grams of propane calculations ) (C 3 H 8 ) how much H 2 O can be produced in ? ( Show all a . moles ? b . grams of H2O ? c . molecules of H20 ? 24. If you conduct this same reaction in the lab with the same amount ( 25 grams propane ) and obtain 31.6 grams of what is the percent yield of ? ( Show calculation ) H 2 O; H 2 O

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.

What three things does a balanced equation show you?
