When sodium metal in water produces hydrogen gas is it a physical property or a chemical property?
The reaction of sodium metal with water to produce hydrogen gas is a chemical property. This is because a new substance (hydrogen gas) is formed as a result of a chemical reaction between sodium and water.
What element is produced when sodium is mixed with water?
When sodium is mixed with water, it produces sodium hydroxide (NaOH) and hydrogen gas (H2). This reaction is highly exothermic and produces enough heat to ignite the hydrogen gas.
Hydrochloric acid reacts with magnesium to produce hydrogen gas is chemical change?
Yes, the reaction between hydrochloric acid and magnesium to produce hydrogen gas is a chemical change. This is because chemical bonds are broken and new bonds are formed, leading to the formation of a new substance (hydrogen gas) with different properties than the original reactants.
When placed in H2O a sodium pellet catches on fire as hydrogen gas is liberated and sodium hydroxide forms chemical or physical change?
This is a chemical change. When sodium reacts with water, it undergoes a chemical reaction to produce hydrogen gas and sodium hydroxide. The formation of new substances (sodium hydroxide) and the evolution of gas (hydrogen) indicate a chemical change rather than a physical one.
What is a reaction where free element element takes the place f an element in a compound?
A single displacement reaction is a type of chemical reaction where a free element replaces another element in a compound. This occurs when a more reactive element displaces a less reactive element in a compound, forming a new compound and releasing the displaced element.
How an element produce heat?
A chemical reaction took place creating a new element.
What structure is most necessary for a mitochondrion to produce new?
hydrogen pump
What is most necessary for a mitochondrion to produce new molecules?
hydrogen pump
Is formation of water from its element physical change?
No, the formation of water from its elements (hydrogen and oxygen) is a chemical change because new substances with different properties are formed. In this case, a chemical reaction occurs between hydrogen and oxygen molecules to produce water molecules.
Which structure is most necessary for mitochondria to produce new molecules?
Hydrogen pump.
A mitochondrion cannot produce new molecules. Which structures is most likely not functioning property?
Hydrogen pump
What is the new substances that are formed from the chemical reactions called?
These are called compounds unless an element, such as hydrogen, has been formed.
What is the most common element in a young star?
The most common element in a young star is hydrogen. During the star formation process, vast amounts of hydrogen gas collapse under gravity to form a new star. This hydrogen fuel is what powers nuclear fusion reactions in the star's core, creating energy and sustaining the star's brightness.
Do Hydrogen fuel cell have impact on society?
Yes, of course. It takes raw materials and engergy to produce a hydrogen fuel cell. It then takes raw materials and energy to produce the hydrogen fuel. However, the result of the hydrogen fuel cell combustion is water - this is a significant improvement over regular internal combustion engines which produce all kinds of exhaust fumes.Assuming hydrogren fuel cells become wide spread then society will change in many ways from new jobs and new fuel refineries/distribution to new language/slang for the HFCs etc...
How does a nuclear plant work?
A nuclear energy plant produces electricity by either nuclear fusion or fission. Fusion is the combining of two atoms of the same element (such as hydrogen) to produce a new element (helium). Fission is the process of breaking down a large unstable atom of one element into two different elements. Both fusion and fission produce enormous amounts of energy and heat. The heat produced is used to heat water into steam which is then used to rotate the blades of a turbine which produces electricity.
2003 Subaru Forester after replacing a blown fuse for lighter with two new fuses the lighters still don't work any suggestions?
replace socket and element
What is the longest stage in the life cycle of a star?
The longest stage in the life cycle of a star is the main sequence stage, where a star fuses hydrogen into helium in its core. This stage can last for billions of years, depending on the mass of the star.
