What else can I help you with?
You are a noble gas with a mass no of 19?
The element with a mass number of 19 could be fluorine, which is a halogen and a gas, but not a noble gas.
How could you use a balloon and a balance to show that gases really do have a gas?
To demonstrate that gases have mass using a balloon and a balance, first inflate the balloon and then weigh it on the balance. Next, deflate the balloon and weigh it again. The difference in weight before and after deflation shows that the gas inside the balloon (air) has mass, confirming that gases indeed possess weight.
How can demonstrate that a piece of chalk mass has mass?
Put it on a balance and determine its mass.
What is the atomic mass 20 gas?
The atomic mass of an element is the average mass of an atom of that element. For a gas with an atomic mass of 20, it could be calcium (Ca). Calcium has an atomic number of 20 and an atomic mass of approximately 40.08 grams per mole.
Why is it hard to prove the law of conservation of mass when a gas is produced?
Proving the law of conservation of mass is challenging when a gas is produced because gases can easily escape from a closed system, leading to a loss of mass that isn't accounted for in the reaction. In open systems, the gas may diffuse into the environment, making it difficult to measure the total mass before and after the reaction accurately. Additionally, gases can be difficult to capture or contain, which complicates the experimental setup needed to demonstrate that mass is conserved.
Does gas have definite mass?
Yes, gas has mass. The mass of a gas is determined by the number of gas particles present and the type of gas molecules. The mass of gas can be measured using a balance or by determining the mass of the container before and after the gas is added.
How could a chemist find out how much mass is given off as gas during a chemical change?
How could a chemist find out how much mass is given off as gas during a chemical reaction
How can you demonstrate that a piece of chalk has mass?
You can demonstrate that a piece of chalk has mass by weighing it on a scale. Place the chalk on the scale and observe the reading, which indicates the gravitational force acting on the chalk due to its mass. A non-zero reading confirms that the chalk has mass.
Molecular mass equals 2vapour density?
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
Why would an experiment not demonstrate the law of conservation of mass?
An experiment may not demonstrate the law of conservation of mass if there are sources of error, such as incomplete data collection or unaccounted-for mass changes (e.g., evaporation, chemical reactions) during the experiment. Additionally, equipment malfunctions or improper experimental design could also lead to inaccurate results that do not align with the law of conservation of mass.
How does breathing demonstrate gases are fluids?
Your breath is a gas
Balanced chemical equations demonstrate?
