Distillation is a widely used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points , into the gas phase .
<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.
<span>No. Zn can only have oxidation states of 1+ or 2+. For this compound to be able to exist, the Zn would have to have an oxidation state of 2- to counteract the 2+ from the 2 sodium ions. Sodium ions each have a +1 charge, so the 2 sodium ions would carry a +2 charge. In order for the compound to exist, the net charge between the 2 sodium and 1 zinc atoms would need to be 0.</span>
I really wish I could help hun but I really don’t know the answers
Without the atmosphere, the greenhouse effect would not be possible.
