Answer:

CHO2- ion

Explanation:

We have the lewis structure of a formate-ion here

This is CHO2-.

The carbon atom is the central atom in the structure. It's the least electronegative atom (C). Carbon has 4 valence electrons. Oxygen has 6 valence electrons.

The carbon will bind with 1 hydrogen atom, this will form 1 single bond, because hydrogen has 1 valence electron.

The carbon will bind with oxygen via a double bond.

Since carbon has only 4 valence electrons, it can only form 1 bond with the other oxygen atom.

There will formed 1 double bond between C and O and 1 single bond between C and O resulting in a negative charged O-atom.

This means there are two resonance structures. for the CHO2-  ion

How big is an electron compared to a proton?
Romashka [77]
A proton has about 1836 times the mass of an electron. The best estimate of physicists is that the radius of a proton is about 8×10-16m and the radius of an electron is about 10-16m . If they are correct, then a proton has about ten times the diameter of an electron

The _____ is the organelle that recycles unneeded molecules
Aneli [31]

Answer: Lysosomes

Explanation: The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.

Many ionic compounds form crystal structures. How and why does this happen?
lesantik [10]
Ions bound together by electrostatic attraction form ionic crystals. ... A simple cubic crystal lattice has ions equally spaced in 3D at 90° angles. Stability of ionic solids depends on lattice energy, which is released in the form of heat when two ions are brought together to form a solid.

What would be the change in pressure in a sealed 10.0 l vessel due to the formation of n2 gas when the ammonium nitrite in 2.40
larisa86 [58]

The  change  in pressure in a sealed 10.0L vessel  is 5.28 atm

<u><em>calculation</em></u>

The pressure is calculated using the ideal gas equation

That is   P=n RT

where;

P (pressure)= ?

v( volume) = 10.0 L

n( number of moles)  which is calculated as below

<em>write the equation  for  decomposition  of   NH₄NO₂</em>

NH₄NO₂  →  N₂  +2H₂O

<em>Find the moles of NH₄NO₂</em>

 moles = molarity x volume in liters

= 2.40 l x 0.900 M =2.16 moles

<em>Use the mole ratio to determine the  moles of N₂</em>

that is from equation above  NH₄NO₂:N₂ is 1:1 therefore the moles of N₂ is also =2.16 moles

R(gas constant) =0.0821 l.atm/mol.K

T(temperature)  = 25° c  into kelvin = 25 +273 =298 K

make p the  subject of the formula  by diving both side  by  V

P = nRT/V

p ={ (2.16 moles x 0.0821 L.atm/mol.K  x 298 K) /10.0 L} = 5.28  atm.
