In terms of ion charges and chemical change, CuF ha +1 charge and CuF₂ has +2 charge. This is the difference between CuF(s) and CuF2(s).
An atom or molecule with a net electrical charge is known as an ion. Conventionally, the charge of an electron is thought to be negative; this charge is equal to and opposite to the charge of a proton, which is thought to be positive.
As stability depends on the hydration energy of the ions when they connect to the water molecules, Cu2+ is more stable than Cu+. Because the Cu2+ ion makes significantly stronger bonds and has a higher charge density than the Cu+ ion, it releases more energy.
Copper(I) ion is created when copper provides one electron to another atom; this accounts for the +1. Copper has one fewer electron than protons. Copper(II).
Thus, In terms of ion charges and chemical change, CuF ha +1 charge and CuF₂ has +2 charge.

Explanation:
The number of valence electrons or outermost electrons present in an atom determines the chemical properties of an atom.
Therefore, atoms belonging to same group have same number of valence electrons. Thus, atoms of a group have similar chemical properties.
Hence, we can conclude that the number of valence electrons in each atom of an element affects the elements chemical properties.
The number of electrons in an atom's outermost valence shell governs its chemical properties. Elements react to form a closed shell, corresponding to the electron configuration s2p6 . This tendency is called the octet rule, because the atoms have eight valence electrons.
b. Heat is transferred from the system to the surroundings in an endothermic
process.
c. The SI unit of specific heat capacity is calories per gram (cal/g).
d. Specific heat capacity is a positive value for liquids and a negative value for
solids.
e. The larger the heat capacity of an object, the more energy it takes it is to
cause a ten degree increase in temperature,

Answer: cochlea
The cochlea is responsible for turning sound waves which is what makes you hear.
b.is it a physical or chemical change .
Answer:
vinegar and baking soda when mixed forms Carbon dioxide which turns lime water milky.
Explanation:
due to properties of Co2 lime water turns milky. The Answer would be A
We are required to explain the meaning of volume and mention the instrument used to measure liquid volume.
Since, volume comprises of length, width and height, then the formula used to calculate the volume of a solid object is length multiplied by width multiplied by height.
Therefore,
Volume of a solid object = Length × Width × Height

Answer:
Volume is the amount of space that a substance occupies. A graduated cylinder is used to measure liquid volume. The formula used to calculate the volume of a solid object is = L x W x H
