According  to  octet  rule  element  has  eight  electrons  in  its valence shell.This  give it  the  same  electronic  configuration  as  a  group  18  elements.Atom  with  electronic  configuration  1s2 2s2 2p1  require  five  electrons  to  achieve  octet. This  is  because the  valence  electrons  are  3 in 2s2  and 2p1  and  hence require  5  electrons  to  be  filled.

Aluminum sulfate is added to tripotassium phosphate. What kind of chemical reaction is this?
alina1380 [7]

Answer:

Double Replacement

Explanation:

Let's consider the following balanced reaction that occurs between aluminum sulfate and tripotassium phosphate.

Al₂(SO₄)₃ + 2 K₃PO₄ ⇒ 2 AlPO₄ + 3 K₂SO₄

This is a double replacement reaction because both salts exchange their cations and anions. So, PO₄³⁻ takes the place of SO₄²⁻ in Al₂(SO₄)₃ and SO₄²⁻ takes the place of PO₄³⁻ in K₃PO₄.

What mass of CCl4 is required to prepare a 0.25 m solution using 115 g of hexane? (molar mass of ccl4 = 153.81 g/mol and molar m
natka813 [3]

4.42 g mass of CCl4 is required to prepare a 0.25 m solution using 115 g of hexane.

It's easy to find the molecular mass of a compound with these steps: Determine the molecular formula of the molecule. Use the periodic table to determine the atomic mass of each element in the molecule. Multiply each element's atomic mass by the number of atoms of that element in the molecule.

The molar mass of any compound can be found out by adding the relative atomic masses of each element present in that particular compound.

Hexane is an organic compound, a straight-chain alkane with six carbon atoms and has the molecular formula C₆H₁₄.

Therefore,

⇒ 0.115 g of Hexane x (0.25 mol CCl4/1 mol hexane) x (153.81 g of CCl4/1 mol CCl4) = 4.42g CCl4.
