Identify the correct statements associated with titration.

Titration requires a buret to accurately measure the volume of a solution.
Titration can determine the concentration of one reactant in an aqueous reactioln.
Endpoints in acid-base titration can be determined by a color indicator or a pH meter
a. 1,2, and 3 are correct
b. 1 and 2 are correct
c. 2 and 3 are correct
d. only 1 is correct

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?

In a heat of an engine, if 700 j enters the system, and the piston does 400 j of work what is the final internal (thermal) energy of the system if the initial energy is 1,500 j
