The answer for it is C. when you mix it with water it fizzes
Explanation:
1) their is no formation of new substance
2) the reaction can be reverse i.e if we heat sugar solution it we give us sugar and water.
12cm cubed.
Formula is length x width x height and in this case it would be 2x3x2 which equals 23
An acid, acids have a pH less than 7
5 electrons
Boron atomic number 5 has five electrons in its ground state.
Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form.
Explanation:
The atomic number gives the number of protons. Protons which have a positive charge are balanced by an equal number of electrons in a neutral atom.
Boron number 5 has five protons and therefore as a neutral atom also has five electrons.
Boron has an electron configuration of
1s22s22p1
The most stable electron configuration for Boron is
1s2
+ 3 charges. By losing three electrons Boron can achieve the stable electron structure of Helium
