Final answer:
The correct IUPAC chemical names for Copper chloride, Copper bromide, Copper iodide, and Copper hydride are Copper(II) chloride, Copper(II) bromide, Copper(II) iodide, and Copper hydride respectively.
Explanation:
In accordance with International Union of Pure and Applied Chemistry (IUPAC) naming conventions, the chemical names for the given formulas are as follows:
- Copper chloride is referred to as copper(II) chloride in the IUPAC naming system as it contains the copper(II) ion, which has a +2 charge.
- Copper bromide is named copper(II) bromide, reflecting the +2 charge of the copper(II) ion.
- Copper iodide is termed copper(II) iodide to denote the +2 charge of the copper(II) ion.
- Copper hydride is an exception as it is simply named copper hydride in IUPAC nomenclature.

Molarity = 2.0 moles / 2.0 L
Molarity = 1.0 M
Answer:
1.0 M
Explanation:
Hello,
Molarity is a unit of concentration accounting for the amount of the moles of a solute per liter of solution as shown below:
In such a way, given the information on the statement, the resulting molarity turns out into:
Do not forget that mol per liters means molar units (M) as well.
Best regards.

2. the carrying capacity is around 24 since that is when they reach population equilibrium.
3. This will lower the mice population since it will introduce a predator that will lower the carrying capacity.
4. The mice population can change in the future if more predators are introduced, if predators die out/go away, if an invasive species is introduced that competes with the mice for resources, if the climate changes, and if the amount of resources available to the mice increases or decreases.

Anything that has physical or real existence is matter. Everything that exists in the known universe manifests itself as matter or energy.
Matter can be liquid, solid or gaseous. Examples of raw: paper, wood, air, water, stone.
Matter is anything that has mass and occupies space.
What is matter?
In science, matter is anything that has mass and occupies space. This means that matter has volume and mass.
Matter is made up of tiny particles called atoms. Atoms are the basic building blocks of matter. They are the smallest units of matter that can exist independently.
The properties of matter are determined by the composition of the atoms that make up the matter. For example, the boiling point of a liquid is determined by the strength of the intermolecular forces between the molecules of the liquid.
