Why is aluminum metal used to be remove tarnish from silver?
Aluminum metal is used to remove tarnish from silver due to a chemical reaction known as the "aluminum-silver" reaction. When aluminum is placed in contact with tarnished silver in the presence of an electrolyte, such as baking soda and water, the aluminum reduces silver sulfide (the tarnish) back to silver while itself being oxidized. This process effectively cleans the silver without damaging it, making aluminum a convenient and effective choice for tarnish removal.
What chemical compound is aluminum chloride?
Al4Cl The compound name is Aluminum Chloride. Al=3- Cl=1+ Chlorine has 7 valence electrons and gains one to become stable making it a positive one charged ion. Aluminum has 3 valence electrons and loses three to become stable making it negative three charged ion.
Is aluminum a renewable recourse?
Aluminum is recyclable by humans but not renewable in the sense of making it. We acquire aluminum by mining and smelting ore containing aluminum.

Making The Most of Leftovers?
When there is leftover food it usually gets stored and placed in the refrigerator to be eaten at another time. Sometimes we forget about it and it’s never touched again until it has gone bad and needs to be thrown out.Feed OthersWhen you’ve cooked a big meal and have leftovers, don’t let it just sit in the back of the refrigerator to never be heard from again. If you feel like that pot roast you only ate half of isn’t going to see the light of day again, try taking it to a local homeless shelter or food kitchen. There are also churches and organizations looking to feed people that will gladly accept your prepared meals to distribute to the hungry.Pack MealsAnother good way to get rid of your leftovers is to pack meals. You can use your leftovers as meals to be eaten later by your spouse or children. You should prepare lunches for your kids to take to school. Just because something isn’t eaten that day doesn’t mean it can’t be eaten the following day.New DishesDon’t assume that last night’s chicken or pork chop can’t be eaten with something else the next day. Having leftovers simply means you’ve saved yourself time in preparing certain food items for dinner tomorrow. Just take leftover food in conjunction with another prepared meal to create a new dish for your family to enjoy.PreserveIf you have leftover vegetables or fruits, you can store them in jars of water and preserve them to be used later. You can even use leftover fruits to create your own jams to be used on sandwiches or for biscuits during breakfast in the morning.DehydrationJust as you can preserve your leftover food items, there are some that can be dehydrated and used afterwards. These items includes meats and fruits that can be turned into jerkies and dried fruit chips. They make for great snacks that can be consumed between meals and during the day.
What physical property does making aluminum foil demonstrate?
Making aluminum foil demonstrates the physical property of malleability, which is the ability of a material to be hammered or rolled into thin sheets without breaking. Aluminum foil is created by rolling aluminum ingots through a series of rollers to achieve the desired thickness.
How many potassium are needed to balance the charge of on sulfide ion?
Normally, 2 K+ ions are required for making a stable ionic bond with one S 2- anion. The compound formed would be Potassium Sulfide (K2S).
What is the ore that goes into the process of making aluminum?

What is the stoichiometry behind making aluminum oxide?
The stoichiometry for making aluminum oxide (Al2O3) involves the reaction between aluminum metal and oxygen gas. The balanced chemical equation is 4Al + 3O2 -> 2Al2O3, which means that 4 moles of aluminum react with 3 moles of oxygen gas to produce 2 moles of aluminum oxide.
