What else can I help you with?
What metal burns in air but only reacts slowly in water?
It depends what you mean by slowly! Calcium burns in air and reacts fairly quietly with water, certainly much more slowly than the alkali metals do.
Do bases oxidize in the air?
Bases aren't oxidized in air.
Why do metals often lose their shine and appear dull?
Most metals lose their luster when they are exposed to water because they react with the oxygen in the water and oxidize. An example is iron that reacts with the water to produce iron oxide, or rust.
Whice metal goes rusty in water?
Only one metal can rust, so the question refers to iron.
What alkali metal's melting point is at room temperature?
Unstable in air or water, they oxidize rapidly and sometimes violently.
Name a disadvantage of ferrous metals?
They generally oxidize with exposure to the moisture in air, producing rust.
What do you mean by noble metals?
The noble metals are a group of metals that resist oxidation and corrosion in moist air. They are the opposite of the base metals, which more readily oxidize and corrode. Some of the noble metals are gold, platinum, and iridium. Aside from being corrosion resistant, they are also very expensive.
What metal burns in air but only reacts slowly in water?
It depends what you mean by slowly! Calcium burns in air and reacts fairly quietly with water, certainly much more slowly than the alkali metals do.
How metals change due to exposure to the air?
Some metals, namely iron, oxidize (that is the metal loses electrons) in the presence of air. This causes a chemical change to iron oxide, which is responsible for rusting.
What are two metals that tarnish quickley in air?
Silver and copper! both will oxidize noticably.
Which Reaction is taking place when metals reacts slowly with air or water?
corrosion?
Metals may naturally oxidize and virtually always?
Metals may naturally oxidize and virtually always have the same oxidation number. An oxidation number is assigned to an element in chemical combination that represents the number of electrons lost or gained.
Do bases oxidize in the air?
Bases aren't oxidized in air.
Metals that grow dull when exposed to air are more than metals that remain shiny?
You seem to be missing a word there. I'm going to guess that you're looking for reactive. Metals that grow dull (or are oxidized) on contact with air are more reactive than metals that don't oxidize in air (or do so very slowly).
Does coffee oxidize when exposed to air?
Yes, coffee does oxidize when exposed to air. This process can affect the flavor and freshness of the coffee over time.
Which is a material in which thermal energy moves slowly?
Air is a material in which thermal energy moves slowly because it is a poor conductor of heat. This means that it does not transfer heat efficiently and thus thermal energy moves more slowly through air compared to materials like metals which are good conductors and allow thermal energy to move quickly.
Can you use the word oxidize in a sentence?
Exposure to air caused the apple to oxidize and turn brown. He didn't want the metal to oxidize, so he applied a coat of primer.
