Oxygen is a gas.
The usual state of oxygen and hydrogen: they are gases at room temperature.
The usual state of oxygen and hydrogen: they are gases at room temperature.
CuO ==== One atom of copper. One atom of oxygen. ( assuming the usual 2 oxidation state of copper )
The word "usual" can be both an adjective or a noun, where the usual condition or status is unspecified (the usual).Other nouns for usual are usualness (state of normality) and the rarely-used usuality.
oxygen's physical state is gas
The usual state of oxygen and hydrogen: they are gases at room temperature.
The usual oxidation state for oxygen in a compound is -2.
The usual state of oxygen and hydrogen: they are gases at room temperature.
In most compounds oxygen will have an oxidation state of -2. The only exceptions are peroxides (-1), superoxides (-1/2), and compounds in which oxygen bonds with fluorine (+1 or +2).
Oxygen is usually found in its Gaseous state in molecular form (O2).
The usual state of oxygen and hydrogen: they are gases at room temperature.
This is the usual formula for elemental oxygen in its gaseous state. It could also be called a "diatomic oxygen molecule."
Usually the oxidation no of oxygen is -2 and the oxidation no of hydrogen is +1 in a compound.
An oxidation state is a number that is assigned to an element in a chemical combination.
the usual state of both hydrogen and nitrogen are gas.
CuO ==== One atom of copper. One atom of oxygen. ( assuming the usual 2 oxidation state of copper )
The valency of oxygen in suboxides can vary, but it is typically less than its usual valency of 2 in oxides. Suboxides contain oxygen atoms with a valency of 1 or less, resulting in a lower overall valency for oxygen in these compounds.
