Are hydrogen and oxygen a change of state?
If water is being split into hydrogen and oxygen then a change of state (phase change) will occur if the water is in liquid form and the hydrogen and oxygen are evolved as gases. If water vapor is being split, then obviously no change of state occurs. Conversely, solid water in the form of ice could be split into hydrogen and oxygen gas, also undergoing a phase change.
Is water being split to form two new substances hydrogen and oxygen a change of state?
No, the process of water being split into hydrogen and oxygen is a chemical change, not a change of state. During this process, new substances are formed through a chemical reaction, rather than a change in the physical state of the water molecules.
What is needed to change the state or form of H20?
Electrolysis can be used to separate H2O into hydrogen and oxygen.
What state of matter is oxygen and hydrogen?
oxygen and hydrogen are a type of matter called gas
What is usual state of oxygen and hydrogen?
The usual state of oxygen and hydrogen: they are gases at room temperature.
What is the usual of oxygen and hydrogen?
The usual state of oxygen and hydrogen: they are gases at room temperature.
Oxygen and hydrogen are in what state?
Gas
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
What is the oxidation state of hydrogen in hydrogen peroxide?
it is +1 because hydrogen loses an electron to oxygen, while that of oxygen is -1 because oxygen gains an electron from hydrogen; thus making the overall charge distribution:+1 (H)-1(O)-1(O)-+1(H)=0.
State one way in which a molecule of hydrogen and a molecule of oxygen differ?
One way in which a molecule of hydrogen and a molecule of oxygen differ is in their chemical formula. A molecule of hydrogen consists of two hydrogen atoms (H2), whereas a molecule of oxygen consists of two oxygen atoms (O2).
What are the oxidation numbers of hydroxide?
The oxidation number of oxygen in hydroxide (OH-) is -2 since oxygen typically has an oxidation number of -2 in compounds. The oxidation number of hydrogen in hydroxide is +1 since hydrogen usually has an oxidation number of +1 when bonded to nonmetals like oxygen.
What is the oxidation number of H2O?
For the hydrogen atoms the oxidation state is 1+, for the oxygen it is 2-
