The answer is C, because if the copper has a +2 charge, the fluoride must have a -2 charge in order to cancel out.
then the electrons and protons would have a even amount of negetive electric charges
Any change in which the composition of material does not change that is it retains its identity but changes its state or form is known as a physical change.
The properties of metal to draw them into wires is known as ductility. When a copper is drawn into wire the only change that occurs is change in its shape and size no change will take place into its composition that is the wires are still possessing the properties of copper metal. Thus, a physical change takes place when copper is drawn into wire.
Answer:
2.57 e-9
Explanation:
The formula is H3O=10^-Ph
10^-8.59=2.57 e-9
Acid of x bottle is highly reactive because solute is more and acid of y bottle is less reactive because solvent is more.
