Is liquifying nitrogen a chemical change?
No, liquifying nitrogen is a physical change. This process involves changing the state of nitrogen from a gas to a liquid without altering its chemical composition.
Why does liquid nitrogen exposed to air is a physical change?
When liquid nitrogen is exposed to air, it rapidly evaporates and turns into nitrogen gas. This process is a physical change because only the physical state of the substance is changed from liquid to gas, without altering its chemical composition.
Bacteria in root nodules change nitrogen gas in what form?
ammonia
Is liquid nitrogen that boils AT - 196 degrees Celsius chemical or physical?
The boiling of liquid nitrogen at -196 degrees Celsius is a physical change because it is a change in state from liquid to gas without changing the chemical composition of nitrogen.
What bacteria in the soil can change nitrogen compounds into?
Some bacteria in the soil, like Rhizobium and Azotobacter, are capable of converting nitrogen gas into a form that plants can use, such as ammonium or nitrates. This process is known as nitrogen fixation and is crucial for plant growth and soil fertility.
What does respiration change?
Respiration (breathing) changes the amount of oxygen and carbon dioxide in the lungs
How does respiration change the amount of another gas in the atmosphere?
it doesnt
Is liquifying nitrogen a chemical change?
No, liquifying nitrogen is a physical change. This process involves changing the state of nitrogen from a gas to a liquid without altering its chemical composition.
What danger we have to face if the proportion of oxygen and nitrogen in the air undergo a change?
Difficult respiration if the oxygen is under 20 % followed by death.
Why does liquid nitrogen exposed to air is a physical change?
When liquid nitrogen is exposed to air, it rapidly evaporates and turns into nitrogen gas. This process is a physical change because only the physical state of the substance is changed from liquid to gas, without altering its chemical composition.
What is Certain bacteria change free nitrogen gas into a usable form in a process?
Nitrogen Cyclenitrogen fixationnitrogennitrogen fixationNitrogen-fixing bacteria
What is process is common between aerobic and anaerobic respiration?
The common process between aerobic and anaerobic respiration is glycolysis, which is the breakdown of glucose into pyruvate. This process occurs in the cytoplasm of cells and produces a small amount of ATP. From there, the pathways diverge with aerobic respiration continuing in the presence of oxygen, while anaerobic respiration proceeds without oxygen through either fermentation or anaerobic respiration.
What type of change is respiration?
Respiration is a chemical process that involves converting oxygen and glucose into energy, carbon dioxide, and water. It is a metabolic change that provides the necessary energy for cellular functions in organisms.
Why do the composition of air change when in the presence of a living organism?
Most likely because of biological respiration processes, when vertebrates and invertebrates take in oxygen (as well as air's main component: nitrogen) and expel carbon dioxide. For Plants, it is the reverse process, taking in carbon dioxide from animals and producing oxygen from the process.
Bacteria in root nodules change nitrogen gas in what form?
ammonia
Is boiling nitrogen in a laboratory a physical or chemical change?
Compression of nitrogen or any gas does not alter the chemical property...only changes involve in physical properties... On compression the gas molecules are come into more close..so it is pressurized..not change its chemical property...and whenever chances is come it s expand ..
Is respiration in animals a reversible change or irreversible change?
No, it isnt. There are chemical reactions while breathing.
