The pure nitrogen is a chemical element, gaseous at room temperature.
Sulfur is an element. Elements are pure substances made up of only one type of atom.
Ammonia (NH3) is a compound, not an element. It is a homogeneous mixture when dissolved in water, but a pure sample of ammonia gas is considered a compound.
The grain alcohol itself is a compound, Ethanol but, it is always found in a mixture with water, making it a solution.
Sodium metal is an element, not a compound or a solution. It is a pure substance that consists of sodium atoms.
24K gold is a pure element, not a compound or solution. It is made up of gold atoms only.
Aluminium is an element . it is not compound or mixture.
silver is an element because, it is a pure chemical substance composed of atoms with the same number of protons.
Sulfur is an element. Elements are pure substances made up of only one type of atom.
No, carbon is not a heterogeneous mixture. It is not a mixture because it is an element. The term heterogeneous can only be applied to mixtures.
No,bromine is not heterogenous.It is a pure element.
Heterogenous. Salt is sodium and chloride.
It's an element. Check your periodic table.
NO!!! Elements and compoounds exists as separate entities. Heterogeneous means a mixture of substances that are in different physical states. Compare to Homogeneous which means a mixture of substances that are in the SAME physical state. However, The element bromine(Br) is liquid at STP. The compound water(H2O) is also a liquid at STP. When mixed together to form bromin water, it is an homogeneous mixture.
Ammonia (NH3) is a compound, not an element. It is a homogeneous mixture when dissolved in water, but a pure sample of ammonia gas is considered a compound.
The grain alcohol itself is a compound, Ethanol but, it is always found in a mixture with water, making it a solution.
Sodium metal is an element, not a compound or a solution. It is a pure substance that consists of sodium atoms.
Sulphur is an element, shown in the Periodic Table as 'S'. It exists in numerous allotropic forms; yellow, red and white.. The ''yellow' allotrope is the commonest form of elemental sulphur. As the 'yellow' form it is sometimes and archaically known as ' 'yellow flowers of sulphur'. In this allotrope, eight(8) atoms of sulphur are combined in a 'twisted' ring, similar to cyclohexane.
