Is helium gas a pure substance?
Yes, helium gas is considered a pure substance because it is made up of only helium atoms. It is a unique element with its own distinct chemical properties and characteristics.
Is forms of gas when heated a physical or chemical property?
The formation of gas when a substance is heated is generally considered a physical change, as it often involves a change in state (like from liquid to gas) without altering the substance's chemical composition. However, if the heating causes a chemical reaction that produces gas (like combustion), it is a chemical change. Thus, whether it is a physical or chemical property depends on the context of the reaction.
What property of a substance does not change when it turns into gas?
The chemical identity of a substance remains the same when it turns into a gas. The type of atoms and their arrangement within the substance do not change during the phase transition from liquid to gas.
What is a new substance that forms as the result of a chemical reaction is a gas?
An example of a new substance that forms as a gas during a chemical reaction is carbon dioxide (CO2). This gas is often produced when carbon-containing compounds, such as glucose, burn in the presence of oxygen.
Why liquid or gas considered a physical prperty?
Liquid and gas are considered physical properties because they describe the state of matter of a substance. Physical properties are characteristics of a substance that can be observed or measured without changing the substance's composition, and whether a substance is in a liquid or gas state is one such observable property.

You tell your Airmen that the chemical used in the gas chamber was developed to be a non-lethal substance and is considered what type of agent?
incapacitating
What is a chemical substance?
A chemical substance is some form of liquid or solid (or gas!) made out of chemicals or elements.
What are the chemical property's of gas?
Gas is a sate of matter, not any specific substance
What property of a substance does not change when it turns into gas?
The chemical identity of a substance remains the same when it turns into a gas. The type of atoms and their arrangement within the substance do not change during the phase transition from liquid to gas.
Why is ammonia gas a single substance?
Ammonia gas is considered a single substance because it is made up of only one type of molecule, which is NH3. It is a pure compound with a specific chemical formula and structure, consisting of a fixed ratio of nitrogen and hydrogen atoms.
Is ability to react with other substance a physical or chemical?
Chemical. If vinegar reacts with baking soda, a new substance is produced. If something new is produced, it is chemical. In chemical reactions, things change what they are. Water splitting into hydrogen gas and oxygen is chemical, because hydrogen gas and oxygen gas is different from water.

Is substance and chemical the same?
Frequently these words are considered as synonyms.
Is bicarbonate considered a basic substance?
Yes, bicarbonate is considered a basic substance because it can act as a weak base in chemical reactions.
