I buy mayonnaise so rarely that I can't remember if it is suppose to have one of those paper seals like on ketchup bottlesI just opened a jar of Best Foods Mayonnaise and it just had the cap seal to itSo.should it have the paper seal?
Sorry, no such element exists.
u dont use reduction for extraction of highly reactive metal like aluminium still if u r stupid enough to try use an even more reactive element that has even higher affinity for oxygen (like sodium n pottasium) though my advice is dont try this
Nowadays I've never seen one without either the plastic seal on the outside, or the one that looks like paper on top/aluminium on the bottom covering the inside.
