Answer:
What is the charge on the barium ion and what is the charge of the hydroxide ion.
Explanation:
To get the correct formula they have to add to zero over all.
Answer:
Sulfate = tetrahedral
Explanation:
N° Geometry Formula
2 linear AX2
3 trigonal-planar AX3 or AX2E
4 tetrahedral AX4/AX3E/AX2E2
a) Nitrate = NO3-
⇒ AX3
⇒ bond angles = 120°
⇒ Coordination number = 3
⇒ Trigonal planar
b) Sulfate = SO42-
The central S
-atom has four electron domains. It has no lone pairs, so the electron geometry and the molecular geometry are tetrahedral.
⇒AX4
⇒ bond angles = 190.5°
⇒Coordination number = 4
⇒Tetrahedral
c) Chlorate = ClO3-
In ClO3-, the central atom is a Chlorine.
It has 7 valence electrons. The three oxygen form a double bond giving three bond pairs. The remaining two electrons make a lone pair. The total of 4 electron pairs shows that the molecule is sp3 hybridised.
The shape of sp3 hybrid molecule is a tetrahedral. But there is a lone pair. So, the geometry is <u>pyramidal</u>.
⇒AX4
⇒ bond angles = 190.5°
⇒Coordination number = 3
⇒pyramidal
Diffference between tetrahedral and pyramidal is that tetrahedral no has a lone pair, and has 4 atoms bonded to the central atom, while pyramidal has 1 lone pair and 3 atoms bonded to the central atom.
Sulfate has a tetrahedral geometry, which is a pyramidal structure
Answer:
Aqueous sodium ions, Aqueous chloride ions
Explanation:
Sodium chloride dissociates into Na+ and Cl- ions in water
Sodium chloride crystals may also be present in case of saturated solution
6.07 grams is the theoretical yield of calcium phosphate (Ca₃(PO₄)₂).
<h3>How we calculate mass from moles?</h3>
Mass of any substance can be calculated by using moles as:
n = W/M, where
W = required mass
M= molar mass
Given chemical reaction is:
3Ca(NO₃)₂ + 2Na₃PO₄ → 6NaNO₃ + Ca₃(PO₄)₂
From the stoichiometry it is clear that:
3 moles of Ca(NO₃)₂ = produce 1 mole of Ca₃(PO₄)₂
Given mass of Ca(NO₃)₂ = 96.1g
Mole of Ca(NO₃)₂ = 96.1g/164g/mol = 0.5859moles
So, 0.5859 moles of Ca(NO₃)₂ = produce 0.5859×1/3 = 0.0196 moles of Ca₃(PO₄)₂
Required mass of Ca₃(PO₄)₂ will be calculated by using moles as:
W = 0.0196mole × 310g/mole = 6.07 grams
Hence, 6.07 grams is the theoretical yield of calcium phosphate.
