Many plants are poisonous because their stems and leaves contain oxalic acid, or sodium oxalate, when ingested, these substances cause swelling of the respiratory tract and suffocation. A standard analysis for determining the amount of oxalate ion, in a sample is to precipitate this species as calcium oxalate, which is insoluble in water. Choose the right net ionic equation for the reaction between sodium oxalate and calcium chloride, in an aqueous solution.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

girl imma just put my comment here because i need a couple point okurrttt
