Aluminium - it is an element... the rest of the substances in your list are compounds.
ammonia
methanolammonia (NH4)ammonia (NH4)
Ammonia can be decomposed by a chemical change. It is a compound made up of nitrogen and hydrogen (NH3) and can break down into its elemental components through processes such as thermal decomposition or reaction with other chemicals. In contrast, iron is an element that can undergo physical and chemical changes but cannot be decomposed into simpler substances, while argon and helium are noble gases and are also elements that cannot be chemically decomposed.
No, sweat is not a pure substance. It is a mixture of water, salts, and other substances like urea and ammonia.
compounds CAN be decomposed elements CANTThe answer would be Mercury because it is an element and can't be broken down by chemical means. but methane, ethanol and ammonia can be broken down by physical means because they are compounds.
ammonia
methanolammonia (NH4)ammonia (NH4)
Gaseous ammonia is a pure substance because it is made up of only one type of molecule, which is ammonia (NH3). It does not contain any other substances or compounds.
Ammonia (NH3) is a pure substance. It is a compound made up of nitrogen and hydrogen in a fixed ratio, and it cannot be separated into simpler substances by physical means.
No, sweat is not a pure substance. It is a mixture of water, salts, and other substances like urea and ammonia.
No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. Sodium sulfite will only act as a base, and thus it is not amphoteric.
Ammonia is a pure substance because it is a compound made of individual ammonia molecules with a consistent chemical composition (NH3).
compounds CAN be decomposed elements CANTThe answer would be Mercury because it is an element and can't be broken down by chemical means. but methane, ethanol and ammonia can be broken down by physical means because they are compounds.
A substance with a pH level of 11 is considered to be alkaline, and examples include household ammonia, oven cleaner, and some laundry detergents. These substances have a high concentration of hydroxide ions, which makes them basic on the pH scale.
Corrosive substance can be removed with contrasting pH substances. Because corrosive substances are acidic or low on the pH scale, the solution to remove them needs to be high in the pH scale, or basic. Ammonia is an example of a basic solution.
When treating water, ozone alone has no effect on ammonia. If bromine is present, ozone can oxidize bromine eventually to bromate, and bromate will convert ammonia to nitrogen gas and water. For more, search for "breakpoint bromination".
A substance with a pH level of 12 is considered to be very basic or alkaline. Examples of substances with a pH of 12 include household ammonia and sodium hydroxide (lye).
