Is the formula of oxide a chemical or physical property?
Reacting with oxygen to form an oxide is a chemical property.
You make water by reacting hydrogen and oxygen gases is this water same to drink?
yes
Will sodium and calcium form an ionic bond?
Yes when reacting with a nonmetal like oxygen or chlorine No when reacting with each other or other metals and hydrogen
What volume of oxygen will remain after reacting 8cm3 of hydrogen with 20cm3 of oxygen?
Where 2H2 + O2 --> 2H2O, you will have 16 cm3 oxygen remaining after the reaction.
Is combining hydrogen and oxygen to make water is a physical?
No.
Is the formula of oxide a chemical or physical property?
Reacting with oxygen to form an oxide is a chemical property.
Is being composed of hydrogen and oxygen a physical property of water?
Yes, being composed of hydrogen and oxygen is a physical property of water. Physical properties refer to characteristics that can be observed or measured without changing the composition or identity of a substance, and the specific arrangement of hydrogen and oxygen atoms in water molecules is a defining physical property of water.
Which of these is not a gas hydrogen gravity helium oxygen?
Hydrogen, helium and oxygen are gases. Gravity is a physical property of any substance.
What is the difference between property and change?
A property is an aspect of a sustenance, such as its color, density, (physical properties) and what it will and won't react with (chemical properties). A change is just what it sounds like, something changing. Examples include ice melting, or glass shattering (physical changes) or oxygen reacting with hydrogen to form water (a chemical change).
Is water a physical properties?
Evaporation is a physical process.
Why does water not have the same physical and chemical property then hydrogen and oxygen?
Because molecules have other chemical and physical properties than the containing atoms !
What is the result of hydrogen reacting with oxygen?
H2 + 1/2 O2 ---------> H2O
You make water by reacting hydrogen and oxygen gases is this water same to drink?
yes
Why water is regarded as a compound although it can be separated into hydrogen and oxygen by passing an electric current?
The property of copounds is that they can be seperated only by hemical means and not by physical means. Water is a compound since it cannot be seperated by physical means. Seperation into hydrogen and oxygen is a chemical mean.
Will sodium and calcium form an ionic bond?
Yes when reacting with a nonmetal like oxygen or chlorine No when reacting with each other or other metals and hydrogen
Why doesn't Saturn catch fire when it lightnings?
Although the atmosphere of Saturn is mostly hydrogen, that hydrogen cannot burn as Saturn's atmosphere has little or no oxygen. When hydrogen burns it is reacting with oxygen to form water.
What volume of oxygen will remain after reacting 8cm3 of hydrogen with 20cm3 of oxygen?
Where 2H2 + O2 --> 2H2O, you will have 16 cm3 oxygen remaining after the reaction.
