Element that is a yellow solid found as an impurity in coal?
An element that is a yellow solid and found as an impurity in coal is sulfur. Sulfur is one reason why burning coal creates pollution. When impure coal is burned, sulfur dioxide is created and contributes to phenomena such as acid rain.
What is the constituent element of leavening agents?
The constituent element of leavening agents is typically a chemical compound that produces carbon dioxide gas when combined with an acidic ingredient, such as baking powder or yeast. This gas helps dough or batter rise and become light and airy during baking.
Which element produces a blue precipitate?
Copper produces a blue precipitate when it reacts with ammonia.
Compounds combined with the element sulfur is what kind of mineral?
Compounds combined with the element sulfur form sulfide minerals, which are a type of mineral that commonly includes minerals such as pyrite, galena, and chalcopyrite.
Is argon an element compound or a mixture?
Argon is an element. It is a noble gas that exists as individual atoms and is not chemically combined with other elements.
What element when combined with oxygen produces a compound essential to life?
Hydrogen
How conductvity of semiconductors changes with the presence of impurities?
If the impurity is of type "n" - an element (the impurity) that has 5 electrons in its outer shell - conduction will be mainly via electrons. If the impurity is of type "p" - the atoms of the impurity has 3 electrons in its outer shell - the conduction will be mainly via holes.
What element is the donor impurity in silicon?
Silicon has 4 valence electrons. When a penta-valent impurity like phosphorus is added, conduction takes place through the excess electron, the donor. Arsenic is another good example of a donor impurity
Oxygen combined with one other element is an?
Oxygen combined with one other element is an oxide.
What is the name of the element that is combined with alumiium in al2o3?
The element combined with aluminum in Al2O3 is oxygen.
Element that is a yellow solid found as an impurity in coal?

What happens when divalent impurity is doped with trivalent element?
will there be any structural changes when divalent is doped with trivalent
Which element produces a red flame when it reacts with water?
Lithium is the element that produces a red flame when it reacts with water.
What element is two or more elements or compounds phisically combined?
If there are two or more elements or compounds physically combined, then it can no longer be an element.
What element can be combined with chlorine to make salt?
This element is sodium (Na).
What element produces thorium?
Thorium is a natural chemical element.
What element is combined with neon to form an exotic compound?
