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 an Atoms identity?
The number of protons in the nucleus of the atom determine its identity.
How does changing the amount of one substance affect a mixtures identity and a compounds identity?
The compounds identity remain unchanged; but the new mixture is different.
When an atom is broken down into parts what happens to its identity?
This atom loss his identity.
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?
The molar concentration of a gas at standard temperature and pressure (STP) does not depend on the identity of the gas because at STP, all gases occupy the same volume per mole, which is 22.4 liters. This is based on Avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain the same number of molecules.
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.
Which number is known as the additive identity which number is the multiplicative identity?
Additive identity: zero. Multiplicative identity: one.
What is the plural of identity?
The plural of identity is identities.
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.
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.
