what is the structure of XeO2F2???i know its hybridization as sp3d but cannot quite understand its diagram in free space,help an
skelet666 [1.2K]
The shape of XeO₂F₂ is Trigonal bi-pyramidal see-saw tetrahedron (see attached pictures)
- As you said the hybridization of Xe here is sp³d so its geometry has to be Trigonal bi-pyramidal in which F atom located on axial positions but for the final shape we exclude lone pair on Xe to give see-saw shape (see second picture) 
- Remember that we have 5 pairs (4 bond pairs + 1 lone pair) and we have to place lone pair at equatorial position.

10.0 ml of 1.00 M HCl neutralized 20.0 ml of a NaOH solution. What was the molarity of the NaOH?
Viefleur [7K]

Answer:

0.500 M

Explanation:

The balanced equation for the neutralization reaction is as follows

NaOH + HCl —> NaCl + H2O

Molar ratio of NaOH to HCl is 1:1

Number of moles of NaOH reacted is equal to the number of HCl moles

We can use the following equation

c1v1 = c2v2

Where c1 is concentration and v1 is volume of HCl

c2 is concentration and v2 is volume of NaOH

Substituting the values

1.00 M x 10.0 mL = c2 x 20.0 mL

c2 = 0.500 M

Concentration of NaOH is 0.500 M

Why do atoms always contain the same number of electrons and protons?
katovenus [111]

Answer:

An electron is a negatively charged subatomic particle and a proton is a positively charged subatomic particle. Positive charge(s) attract negative charge(s) and vice versa. The proton and neutron stay together and attract one another to give the atom an overall charge of zero (neutral). Which is the charge of an atom. When there is an unequal number of protons and neutrons an ion is formed. If the number of protons are more than the electron, a positively charged ion called cation is formed. On the other hand, if the number of electrons are more than the protons a negatively charged ion called anion is formed.
