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.
Hope this helps!
Answer:
=342g
Explanation:
atomic mass of C = 12g
atomic mass of H = 1g
atomic mass of O = 16g
Solution;
C12 H22 O11
= 12 (12) + 22 (1) + 11(16)
= 144+ 22 + 176
= 342g
Molecules are made up of many atoms and can only be separated by chemical means
There are many types of acid or bases. Based on the Arrhenius definition,
* An Arrhenius acid donates H⁺ in a solution (like HCl, HNO₃, H₂SO₄)* An Arrhenius base yield OH⁻ in a solution (like NaOH, KOH, Mg(OH)₂)
Other types of acids and bases are the Lewis acids/bases and the Bronsted-Lowry acids/bases.
