The formula for molariy is nomber of moles/volume
0.5=n/1=>n=0.5 moles
one mole contains 6.023*10^23 molecules
so 0.5 contain 3.0115*10^23 molecules
Answer: TWO WITH LIGHT PINK PRECIPITATE IS
BaCI2 and AI2(SO4)3 AND BaCI2 and NaOH
Ferric hydroxide and aluminium hydroxide are the precipitate u can form by any major reaction.
Explanation: Chemical Reaction: BaCl2 and AgNO3
Ba+2= Barium= Metal
Cl-1= Chlorine = Non-metal
Ag+1 = Silver= Transition Metal
NO3 - = Nitrate= Polyatomic Ion
BaCl2 = Barium chloride
Ag(NO3) = Silver (I) Nitrate
Answer: 2.0 grams per cubic centimeter
Explanation: i had this
Answer:
14. (C) -3; 16. B. 0, 3
Explanation:
14. Ionic charge
X: ns²np³.
The element is three electrons short of having a complete octet.
It is likely to react chemically to add those three electrons and form an X³⁻ ion.
16. Orbitals in subshells
The n = 1 shell contains no p orbitals. All the other shells contain three p orbitals.
The n = 1 shell contains only one s orbital. Every higher shell contains a p subshell, and each p subshell contains three p orbitals.
