Compounds are classified as binary or ternary based on the number of elements present in the compound. The chemical formulas for the given compounds include nickel(III)oxide, copper(II)iodide, tin(IV)nitride, chloro minimium(II)bromide, and iron(III)phosphide.
In order to identify whether a compound is binary or ternary, we need to analyze its chemical formula. Binary compounds consist of two elements, while ternary compounds consist of three or more elements. The chemical formula for each compound is as follows:

Explanation:
The IUPAC name for the compound ZnO is zinc oxide.
The International Union of Pure and Applied Chemistry (IUPAC) is responsible for standardizing the naming of chemical compounds to ensure uniformity and clarity in chemical nomenclature. In the IUPAC system, chemical names are based on the elements present in the compound and their respective oxidation states.
In the compound ZnO, "Zn" represents the element zinc, and "O" represents the element oxygen. The oxidation state of zinc in this compound is +2, and the oxidation state of oxygen is -2. To form a neutral compound, one zinc ion (Zn²⁺) combines with one oxide ion (O²⁻) in a 1:1 ratio. Therefore, the IUPAC name for the compound ZnO is "zinc oxide."
Zinc oxide is a white powder that is commonly used in various applications, such as in the production of rubber, ceramics, and cosmetics. It is also used as a pigment in paints and as an additive in food products. The IUPAC naming system ensures that scientists and chemists worldwide can communicate effectively about chemical compounds and their properties.

In order to calculate the volume of 0.0023 moles of CO2, we use the ideal gas law and understand that one mole of an ideal gas at standard temperature and pressure occupies a volume of 22.4 liters. The volume for 0.0023 moles of CO2 is found to be approximately 0.05152 liters.
To solve for the volume of the 0.0023 moles of CO2, we need to use the ideal gas law, PV=nRT, where P depicts the pressure, V signifies the volume we need to find, n equals the number of moles, R denotes the universal gas constant, and T denotes the temperature. Assuming the relationship takes place at standard temperature and pressure (STP, 0 degrees Celsius, 1 atm), we can solve for V.
At STP, 1 mole of any ideal gas occupies a volume of 22.4 liters. Therefore, V = n * (Volume of 1 mole at STP), which equals 0.0023 moles * 22.4 L/mole = 0.05152 liters.
