Question:

A3Sources of hydrogen?

3Action of Metals on Acids1.Place approximately 5ml of 6 N HCl in each of the five test tubes2.To the first test tube, add a small strip of magnesium ribbon3.Test the issuing gas by inverting a dry test tube over the first in order to collect the gas4.Move the inverted test tube sideward and quickly insert a burning splint5.Add to the second test tube, a small piece of aluminum; to the third, a small clean iron nail; to the fourth, a piece of mossy zinc; and to the fifth, a piece of copper wire6.Invert a clean and dry test tube to each of the reacted substances7.Test the presence of the gas with burning splint from each inverted test tubeQ1Which of the metals can displace hydrogen from hydrochloric acid?Q2What metals cannot displace hydrogen from hydrochloric acid?

Answer:

cast iron pan or glass no problem other pans would depend on handle is it plastic or wood which wood char meatballs I mix 1/2 envelope of onion soup a couple of tbsp of ketchup some seasoned breadcrumbs and an egg shape and bake on cookie sheet no need for top of stove
If your pan is completly stainless steele, meaning the handle and lid as well then it is ok to put it the ovenOtherwise I would't do it.
The pan sure is, it's stainless ; but is the lid temperedThe description doesn't say.Only that it's dishwasher safe,( which is the worst thing to do with stainless)Good pan, though.
The pan looks oven safe, it doesn't have a plastic handleHere's an easy recipe for meatballs: pound combined beef, veal, pork (must be fresh) 3 large eggs 1 cup grated Romano Locatelli Cheese 1 cup bread crumb 1 clove garlic - minced 1 teaspoon salt (All mixing is done be hand) In a large bowl mix beef/veal/pork with eggsThen add bread crumb, cheese, and saltFinally add minced garlic in stagesAdd a little then mixAdd some more, then mixThis way all the garlic does not end up in one meatballNow, it's time to roll up the ballsAverage size is roughly 2 inches in diameterI usually get around 18 to 20 meatballs per poundIMPORTANT! Do not cook meatballs in your pasta sauce! Meatballs cooked in sauce loose their flavorThe real key to a tasty meatball is cooking the them in an ovenSo, heat oven to 375Place meatballs on a rack - then on a cookie trayBake for 12 minutes on one side then 10 minutes for the other.
do the test and you will see- by burning the gas in the inverted tube, and if it burns, it is hydrogenYou invert the tube bc hydrogen is lighter than air
