<u>Answer:</u>
Erlenmeyer flask can be heated up with a Bunsen burner.
<u>Explanation:</u>
A bunsen burner is a lab equipment that is used to heat things that aren't made up of anything flammable. The things that are to be heated with a bunsen burner are instruments of material like borosilicate like pyrex.
An Erlenmeyer flask that also goes by the names conical flask or even a titration flask can withstand a large amount of heat from the bunsen burner as it's made up of very thick and resistant glass. A graduated cylinder will not be able to withstand that amount of heat and a plastic pipette is sure to melt.
This is the equation balanced:
<span>BaCl2(aq) + Na2CO3(aq) = BaCO3(s) + 2 NaCl(aq)
Then the coefficient in front of Na Cl is 2.
