Answer:
The physical properties of matter are any properties that can be perceived or observed without changing the chemical identity of the sample. In contrast, chemical properties are those that can only be observed and measured by performing a chemical reaction, thus changing the molecular structure of the sample. Mass (like volume) is an extensive physical property because its value depends on the quantity of the matter, unlike temperature. It is not a chemical property as its measurement includes no chemical reaction and change.

Explanation:
Write a balanced equation, ionic equation and the net ionic equation for the following:
A) Li2SO4 + Sr(NO3)3 --->
B) H2SO4 + Na2CO3 --->
You made a typo: that's Sr(NO3)2
Molecular:
Li2SO4(aq) + Sr(NO3)2(aq) ==> SrSO4(s) + 2LiNO3(aq)
ionic:
2Li^+(aq) + SO4^2-(aq) + Sr^2+(aq) + 2 NO3^-(aq) ==> SrSO4(s) + 2Li^+(aq) + 2NO3^-(aq)
NET ionic:
Just cancel the ions common to both sides to leave you with
Sr^2+(aq) + SO4^2-(aq) ==> SrSO4(s)
Ionic bond is formed by metals and non metals so copper reacts with fluorine by donating 2 electrons to two fluorine atoms so as to gain an octet structure.
Cu + Fl₂→ CuFl₂
Cu²⁺ + Fl⁻→ CuFl₂
copper atoms have metallic bonds so also hydrogen atoms. while hydrogen and oxygen atoms have covalent bonds.
