Gas is a state of matter characterized by low density, high compressibility, and the ability to expand to fill a container. It consists of individual atoms or molecules that move freely and independently of each other. Some common examples of gases include oxygen, nitrogen, and carbon dioxide.

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.
How could you test the gas released in reaction 6 to confirm its indentity?
To confirm the identity of the gas released in reaction 6, you could perform tests such as the pop test (putting a lit splint near the gas to see if it ignites with a pop), the limewater test (passing the gas through limewater to see if it turns milky, indicating the presence of carbon dioxide), or using a gas sensor to analyze the chemical composition of the gas.
What is observed without changing identity and has mass and volume?
The substance that is observed without changing its identity while possessing mass and volume is called a "pure substance." This includes elements and compounds that maintain their chemical properties during measurement or observation. For instance, a sample of water retains its identity as H₂O, regardless of its state (solid, liquid, or gas) while being measured for mass and volume.
Given 1.00 mole of each what gases at STP which gas would have the greatest volume?
At STP (standard temperature and pressure), all gases have the same volume of 22.4 liters per mole regardless of their identity. Therefore, 1.00 mole of each gas would occupy the same volume of 22.4 liters.
What can happen to an ideal gas and what can not happen to an ideal gas?
The ideal gas laws describe the relationship of temperature, pressure, and volume for an ideal gas; these three factors are all directly related to each other. Other than that, the behavior of a gas depends upon its chemical identity. They have different boiling points and freezing points, different density, different types of chemical reactions that they undergo, etc., depending upon which specific gas we are talking about.
How does the molar volume at standard temperature and pressure depend upon the identity of the gas?
The molar volume doesn't depend on the identity of the gas. One mole of any ideal gas at STP will occupy 22.4 liters.
How does the molar concentration at Standard temperature and pressure depend upon the identity of the gas?
Molar concentration is defined as the amount of a gas divided by the volume of gas. According to the gas identity, at standard temperature and pressure, even if the amount of the gas is constant, the volume of gas changes. Thus, the molar concentration changes depending on the gas identity.
When would a gas at room temperature change to a liquid?
It depends on the identity of the gas. Different compounds have different melting points.
A 22.0 gram sample of an unknown gas occupies 11.2 liters at STP What is the identity of the gas?
Based on the ideal gas law, we can calculate the molar mass of the gas to determine its identity. Using the formula PV = nRT and knowing that at STP, the pressure is 1 atm and the temperature is 273 K, we can find the number of moles of gas. Then, dividing the mass of the gas by the number of moles will give us the molar mass, allowing us to identify the gas.
If you have 27 g of an unknown substance A and 75 g of chlorine gas Substance A contains 1.5 times as many molecules as the chlorine gas what is the identity of A?

A characteristic of matter that is exhibited without a change in identity?
the volume or mass of the matter. it can change states such as solid liquid or gas, which would be deemed to be the same chemical identity, but a different state of matter
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 does the glowing split test suggest about the identity of the gas evolved in manganese oxide?
The glowing split test suggests that the gas evolved in manganese oxide is likely oxygen. This is because manganese oxide can decompose to release oxygen gas, which would support the glowing splint test result.
How could you test the gas released in reaction 6 to confirm its indentity?
To confirm the identity of the gas released in reaction 6, you could perform tests such as the pop test (putting a lit splint near the gas to see if it ignites with a pop), the limewater test (passing the gas through limewater to see if it turns milky, indicating the presence of carbon dioxide), or using a gas sensor to analyze the chemical composition of the gas.
Is neon gay?
Neon, as a chemical element, does not possess sexual orientation or identity, as it is an inert gas with no biological or social characteristics. The concept of "gay" pertains to human sexual orientation and identity. If you meant something else by "neon," please clarify for a more accurate response.
Why is photsynthesis a chemical change?
Photosynthesis is a chemical change because the identity of the substances involved changes. Water and carbon dioxide are converted into oxygen gas and sugars.
Which number is known as the additive identity which number is the multiplicative identity?
Additive identity: zero. Multiplicative identity: one.
