How do you know that methane and hydrogen are different gasses?
Methane and hydrogen are different gases because they have different chemical compositions and properties. Methane (CH4) is composed of carbon and hydrogen atoms, while hydrogen (H2) is composed solely of hydrogen atoms. Additionally, they have different physical properties such as boiling and melting points.
Why does water and hydrogen peroxide have different properties?
They are totally different compounds, even though they both contain hydrogen and oxygen. The ratios of the elements are not the same. The formula for water is H2O, and for hydrogen peroxide is H2O2. In a molecule of water, two hydrogen atoms are chemically bonded to one oxygen atom, whereas in one molecule of hydrogen peroxide, there are two atoms of hydrogen and two atoms of oxygen bonded together. This makes them completely different compounds with different properties.
Are the atoms the same or different in hydrogen?
All hydrogen atoms are the same but they are different from the atoms of other elements.
Is it true that all atoms of hydrogen have the same chemical and physical properties?
No it’s just like a snowflake there are all different
why air is a mixture and water is a compound?
Air is composed of many different gases that are not chemically combined and retain their individual properties. Water is a compound because it is composed of two hydrogen atoms chemically bonded to an oxygen atom, and the properties of water are different from the properties of the elements hydrogen and oxygen.
Does a compound produce a new substance with unique qualities?
Compounds are made out of atoms of different elements. The properties are different than the properties of the constituent elements.For example, Water is made out of Hydrogen and Oxygen. Both Oxygen and Hydrogen are gasses at room temperature. Water is a liquid at room temperature with very different properties.
A combination of two or more atoms that has physical and chemical properties that differ from the atoms that compose it is called?
I'm pretty sure is is a Compound. A compound is a substance that is made up of more than on element. The properties of matter mostly depend on how atoms of different elements are combined in compounds.
Are hydrogen atoms different to oxygen atoms?
no
Why is air considered a mixture and water a compound?
Air is composed of many different gases that are not chemically combined and retain their individual properties. Water is a compound because it is composed of two hydrogen atoms chemically bonded to an oxygen atom, and the properties of water are different from the properties of the elements hydrogen and oxygen.
Why one mole of hydrogen molecule and one mole of hydrogen atoms have different masses?
because there are 2 hydrogen atoms in the molecule of hydrogen atoms
What happens to the properties of atoms a when they are joined through a chemical reaction to form a compound?
When different atoms join, a new substance is formed that has properties that differ from the properties of the original atoms. Example: Hydrogen and oxygen separately are colorless, odorless gases at room temperature. When combined in a chemical reaction, they form water.
Two or more atoms of different elements form?
Two or more atoms of different elements can form a bound state where they are bonded one with the other. The resulting complex is called a molecule and has chemical and physical properties completely different from the constituting atoms. An example is water, whose molecule is formed by two hydrogen and one oxygen atoms bonded via the so called covalent bond, that forms when different atoms put an electron in common. Water, liquid at room conditions, has completely different properties from both oxygen and hydrogen, both gasses at room conditions.
