CaCl2 + H2O are produced when HCl react with Ca(OH)2
Explanation
equation for reaction is as follows
Ca(OH)2 + 2HCl → CaCl2 +2H2O
1 mole of calcium hydroxide (Ca(OH)2 reacted with 2 moles of hydrochroric acid (HCl) to form 1 moles of calcium chloride CaCl2 and water H2O. This type of reaction is known as neutralization reaction since it between an acid (HCl) and a base (Ca(OH)2
3. The Chemical property of an unknown element is the number of valence electrons
4. The number of protons in one atom of an element
Hope I helped :))
8 valence electrons means that the element is stable. When we hear stable, we know the group to look at! Noble gases all have 8 valence electrons making them stable and have a full octet.
Here are some:-
Krypton
Argon
Neon
